Chrome Remote Desktop - An Alternative to Costly Remote Control Programs?

I was advised by Swedish DX-er Stefan Wikander that Chrome Remote Desktop worked very well with his remote Perseus location. Now really, I thought, I tested Chrome's remote solution several years ago and it was a complete disaster at the time.

Over the years I have used LogMeIn (became very expensive), Teamviewer (kicked me out of my free, Personal account) and Splashtop (present choice, excellent tool, USD 100/year). And tested many more. Anyway, I know Stefan as a sensible man, so I decided to test CRD. It has in fact come a long way.

CRD is a "free" extension in Chrome (you pay with your user data), so obviously you need the Chrome browser, and you need a Google account. Chrome needs to be synchronized over the PC or PCs you want to control. Setup is relatively straightforward. I set up one PC to access two other PCs, and when I opened the extension, I was met with this "welcome" page:

When I clicked on the "Smøla 290" PC on top, it opened as a new tab in Chrome, and the PC displayed like this:

It actually loads very quickly, faster than Splashtop. Audio quality is on par, video quality a bit better than Splashtop. What really surprised me was there was no noticeable lag, much better than both Teamviewer and Splashtop.

CRD doesn't have many features, so for a professional user CRD may not be the optimal solution. For the DX-er however: Good video, good audio, file transfer (to and from the unit), copy & paste. Windowed and full screen. Not much more to ask for!

QSL: 4KZ Innisfail, QLD 5055

The 4KZ 1620 kHz 400-watt relay is quite easy to hear at my location, despite the 12,800 km distance.

Not so with their 1.3 kW station on 5055 kHz! After a few futile (albeit random) attempts, I decided in February to monitor and record three top of the hours every day. I also wanted to do an A-B comparison between the Airspy HF+ and the SDRPlay RSP1A. So both were connected to the same antenna, two different PCs with HDSDR running on both. After quite a number of days, the signal was finally readable.

The HF+ is known to be a very sensitive SDR, while the RSP1A is more average when microvolts are measured. So, there "should" be a difference in audio recovery, at least on threshold signals. There was. When signals are very weak and the noise floor is low, better sensitivity is indeed audible. Here is how 4KZ was heard at the time. Headphones recommended.

The 4KZ General Manger Al Kirton is a DX-friendy guy, and sent off a proper QSL card with a sticker and info in the mail.

Airspy HF+ Discovery: Sensitivity Measurements

Time to find out how sensitive the HF+ Discovery is! Since it is basically the same receiver as the HF+, with preselectors, I expected sensitivity on MW to be roughly the same. Which turned out to be true.
On 500 kHz, I measured -110 dBm, on 1000 kHz -111, and on 1500 kHz -110 dBm. Using SDR#, v.1708, 6 kHz bandwidth with AM mode, and a 30 % modulated, 400 Hz signal from the signal generator.

The "Receiver Sensitivity Measurements" table has been updated accordingly. Excellent numbers.

Airspy HF+ Discovery Has Landed

Well admittedly, the Norway transport was on road, taking twice as long as from Shanghai to Oslo. But it arrived! Just fired it up at my home in Tana, no antennas available, so only to get a feel of it (feels warm to touch) and do the latest firmware update. Sensitivity measurements will be done on Friday.

My kitchen weight says 32 grams. By a good margin the lightest SDR I've had so far.

Antenna Test: The NTi MegaDipol MD300DX

Not much is happening DX-wise during the light Arctic summer, but I had the opportunity to check out a dipole antenna sold by, the NTi MegaDipol MD300DX.
For the time being, you can check it out yourself on my KiwiSDR, see link on the right hand side.

Beverage antennas are the norm at my KONG (Kongsfjord, Arctic Norway) location, because I and my co-users are exclusively MW DX-ers. For general listening, especially on SW, other antenna designs may be better, and for some time I have had a 70-metre longwire up as an all-purpose antenna for use with my KiwiSDR. Many years ago I tested a Mini-Whip antenna, and also the venerable Clifton Labs Z1501 active whip. Two years ago I bought a Wellbrook ALA1530LF for noise detection, and made a comparison with the longwire.
There is no doubt that a properly installed longwire antenna is very efficient on a broad frequency spectrum and may be the preferred alternative if space is not a limiting factor. But often space is restricted, necessitating more compact antenna designs.

Enter the NTi MegaDipol MD300DX. The MegaDipol, priced at EUR 400, comprises of an external antenna unit with two detachable 2.5-metre PVC-coated steel wire elements, and an internal power inserter which powers the external unit via the coaxial cable. The inserter can be powered from a 10-15 VDC supply, or from a 5 VDC supply such as a USB port with slightly less IP values. It is worth noting that the MegaDipol is an E-field antenna, so it should be placed in an electrically quiet environment. For omnidirectional reception, the elements should be placed vertically.

My first test of the MegaDipol was done well away from any potential noise sources, 170 meters away in fact. It was fed from a DX-Engineering coaxial cable. I later added a ground connection to the external unit. At my location, the added grounding did not change the noise floor or signal levels, but the general recommendation is to ground the antenna.
Later, I moved the antenna to a pole much closer to the house. The move from 170 meters away to 30 meters away did not change the noise floor or signal levels.

During the comparison, both antennas were connected to DX-Engineering 75-ohm coaxial cables. The longwire in addition had a matching transformer from DX-Engineering and was grounded on both ends. The MegaDipol was also grounded. The antennas were connected to two KiwiSDRs to facilitate accurate comparisons with identical hardware. Both feedlines had RF isolators inserted; The NTi GI 1000 galvanic isolator for the dipole, and the Wellbrook AFI-5030 for the longwire.
So, how does the MegaDipol compare to the longwire?


I was surprised to see the exceptional performance of the MegaDipol on Longwave. The lower down, the better. On my semi-local NRK 153 kHz, gain was typically 20 dB or more higher than the longwire, and the noise floor was a bit lower. So, all in all up to 25 dB better SNR. The difference decreased with higher frequency as my semi-local NDB “BV” on 399 kHz noted “only” a 10-12 dB difference in SNR.


While I had groundwave signals on LW for the comparison, summer daylight limited my comparisons to late evening skywave signals from the south – in the longwire’s lobe. Generally, the longwire does seem to have stronger signals, but the noise floor on the MegaDipol was lower. So, in effect, the difference was only slightly in favour of the longwire.

Shortwave, up to 7 MHz:

A bit like MW performance. The noise floor on the MegaDipol is lower, but so are signal levels. The net result isn’t very different, and one should note that the longwire’s length of 70 meters is very well matched with this part of the spectrum. A shorter longwire would likely not perform as well.

Shortwave, above 7 MHz:

The MegaDipol’s performance compared to the longwire increases with frequency. On a 31-metre band signal, the MegaDipol and the longwire were practically identical in SNR values. From there and up to 30 MHz, the MegaDipol performed increasingly better than the longwire. Skip on 27 MHz was mostly undetected on the longwire. A shorter longwire would probably fare a bit better than the long one, though.


The MegaDipol claims to hear up to 300 MHz. I compared the MegaDipol with a 3-element FM antenna on the FM and DAB frequency ranges. On FM, I only had one rather weak Finnish station to compare. It was fair on the FM antenna, not heard on the MegaDipol. On a 225 MHz DAB channel, both antennas heard the signal, although the FM antenna had a 10-dB better signal level. Noise levels were identical.


By mounting the two elements horizontally instead of vertically, it is possible to add directionality to enhance or reduce signals from chosen directions. Late in the test, NTi supplied me of 5-metre elements, one of which was placed semi-horizontally (sloping from 2.5 to 1.6 meters) off the direction of a wind park a few km away. The signature RFI of the Siemens wind turbines, increased noise levels from around 750 to 500 kHz, was reduced into general noise level when I pointed the horizontal element in its direction. The signals from 153 kHz and 399 kHz were also reduced a few dB, although a deeper null might have been possible if I had placed the direction of the horizontal element more precisely.


It’s a shame that I don’t have the Z1501 active whip anymore. It would have made a very interesting comparison. Since the Z1501 is out of the equation and considering previous comparisons I did with the ALA1530LF, the longwire and the Mini-Whip, I can safely say that the MegaDipol is an excellent overall performer, and the number one compact antenna I have tested so far.  The price tag may be discouraging for some. However, the Wellbrook loop checks in at GBP 225, and even the cheap longwire’s matching transformer is USD 60. So, small, active antennas usually come at a price. Longwires are cheap – if you have the property to fit one.

QSL: PJZ86 R. Curom, Willemstad, Curaçao, 860

"Z86" was heard with quite a good signal on my Perseus SDR at the Smøla island location in mid-February. My first-time logging of a station from Curaçao. I sent off a Facebook report at the time, and received a confirmation today.

Rare Arctic E-skip on FM

A 30-minute, but strong Es opening yesterday brought 70 loggings from Denmark and Sweden. The opening was extremely narrow, comprising all heard stations within an 11 degrees bearing. Distances varied between 1065 and 1872 km.

I used a very modest 3-element FM antenna placed in the attic, connected to an SDRPlay RSP1A running at 8 MHz (6 MHz or so effective). I used SDR Console to decode and record IQ files to an external SSD for later playback.
Very narrow signal path. Log program:

Aerial View of my Radio Location

While enroute to Tromsø on a Wideroe DHC-8 200, we passed Kongsfjord at a perfect angle for taking a photo of my radio location. The arrowhead-like peninsula is named Veines, popular with birdwatchers and hikers. During WWII, the occupants set up a coast defence battery there as a part of Festung Norwegen.

My house is in the black circle. This summer I have an NTi MegaDipol set up in the red circle. The antenna is currently available on the ArcticSDR.

SDRs - Does the Enclosure Matter?

Traditional receivers, and most SDRs, have been encased in aluminium. Conventional wisdom says this is because they need to be protected from RFI. In later years though, some of the SDRPlay SDRs have had plastic enclosures, and the new Airspy HF+ Discovery is also said to be encased in plastic. It's been said that the RSP1A enclosure has an inner metal paint. That could be, but it looks like plastic, and it feels like plastic.

Anyway - aluminium enclosures are offered as a third-party solution to those who prefer metal, and I ordered one. When it arrived, I naturally had to remove the plastic enclosure, so I thought why not test the device with real signals, and without signals, in its original enclosure, the new metal enclosure, and bare? Just to find out how efficient they would be.

So I ran tests on FM and SW with 8 MHz bandwidths and compared spectra and waterfalls in SDR Console.

The results were...interesting. As a matter of fact, there was no difference whatsoever, even when the RSP1A board lay bare on the floor.

So, is conventional wisdom wrong? Not necessarily, my test is circumstantial evidence only. That said, my radio room has four PCs running, 5-6 SDRs and even a couple of rather dirty switching PSUs. So, lots of potential RFI. But the RSP1A was as immune bare as it was enclosed.

I'll keep the metal enclosure though, it's a bit smaller than the original plastic one, and looks much better. And there are other hazards to electrical equipment than RFI. Especially when they're on the floor!

Some Candidates for the MW SDR DX-er

I’ve been a MW DX-er since my teens. Any other part of the radio spectrum is mostly tuned casually. Hence, I tend to evaluate my SDRs only by their MW performance.

A dedicated MW DX-er has some prerequisites for his or her receivers:
  • Sensitive enough to pull in signals in a low signal level environment.
  •  Robust enough to not overload easily when signal levels are high.
  • Access to software which can record and play back the entire MW band as efficiently as possible.

With the SDR being a “software defined radio”, it is true that software does define the radio experience. Software for the MW DX-er is worth a study of its own. However, at this stage, I thought it might be interesting to have a look at hardware that I have either tested myself, or that I think I know enough about to evaluate for MW DX-ing.

I even thought out a rather complex system for ranking the SDRs since they come in a large variety of price and performance levels. But the system relied on too many subjective factors, so for the time I settled for making an “Editor’s Choice” at the end of this article.

Software supplied with the hardware are listed in bold. Only Windows software versions are listed. Links to the SDR's home page and review pages where available.

In the pipeline
Not much, as per May 2019:
Elad FDM-S3 seems to be in its final stage before launch. EUR 950. Two software-selectable antenna ports?
Airspy HF+ Discovery is just around the corner. USD 100. One antenna port. Same sampling bandwidth as today’s HF+
RFSpace CloudSDR – ETA at Q4/18 has been changed to Q4/19. USD 900? Will we see it?

My Picks:

Low price range/entry level: The SDRPlay RSP1A. It is quite sensitive on MW, less so on LW, and may require some attenuation if the signal level is high. 2 MHz low pass filter helps. Several software options. Can double as a sensitive FM and DAB receiver with 6-8 MHz effective bandwidth, depending on PC. All for only USD 109. A steal.

Middle price range: Microtelecom Perseus. It is sensitive on MW and LW, good dynamic range and several third-party options including the bespoke Jaguar Pro/Jaguar Lite software which lifts the Perseus to the top of the sky. EUR 800 but limited stock, occasionally shows up on auction sites. A bit fiddly installation procedure. Others: Elad FDM-S2 (available, EUR 525), RFSpace CloudIQ (out of stock, maybe discontinued, USD 630). The Winradio G31DDC (available, GBP 700) will be a very good alternative if it gets full HDSDR support.

High price range: Winradio G33DDC. Very sensitive, and very good dynamic range. But a hefty price for the performance (GBP 1600), and proprietary software which some may like and some (like me) will not. Others: RFSpace NetSDR, only available on the used market (USD 1450 new). Good sensitivity and dynamic range, several software options.

If IQ recording of the entire MW band is not important, consider the ethernet based KiwiSDR. No IQ recordings, but up to 8 simultaneous channels (USD 300). Audio recordings are possible from all channels. Or the USB based Airspy HF+ with excellent sensitivity and dynamic range. Several software options, 660 kHz alias-free IQ recording (USD 200).

But you will likely discover that IQ recording of the entire MW band is important.

A Second Look at the ColibriNANO SDR

I tested this SDR briefly back in 2017. I never got round to measure its sensitivity back then, and I also hoped that the manufacturer had addressed the many software issues I had. So almost two years after, I did another test. The original write-up (see links to the right) has been updated.

Spoiler: No, it's not worth €300.

A New Look at the Winradio G31DDC

I bought the G31DDC when it was brand new, thinking that this would be an excellent competitor to the Perseus SDR. Actually, it was an excellent receiver, installation goes in a breeze and it uses 12VDC external power, which is a lot easier to find in no-noise versions than 5VDC PSUs. Sensitivity is around -105 dBm, a tad better than the Perseus. But there were "issues"...

First, the Winradio GUI. It is, at least in my opinion, by no means optimised for efficient MW DX. And at the time there were no software alternatives. Second, and by far more important, the IQ files it recorded were not date- and timestamped! Absolutely disastrous, if you record a lot. And to top it all, no scheduler was available. What on earth were they thinking? Later, the G33DDC came along, with the recording issues solved, but still the old inefficient interface. And with the price doubled.

So, after a short while, my Winradio adventure ended.

I did notice later on that dynamic link libraries (dlls) were developed for use with HDSDR, but at that time I had parted with my G31 and G33.

Recently, related to a project I'm working on, I decided to take a new look at the G31DDC. So, I borrowed a unit (thanks TJ!) downloaded the HDSDR dll and tested the unit. Lo and behold, it is a good receiver!  The only downside is that the current dll only supports 1000 kHz sampling (800 kHz alias-free). So, the requirements for a good MW performer are still not met. But I believe that the dll could be revised to allow 1600 kHz alias-free sampling.

Because, with HDSDR, time- and datestamped files and scheduling is no problem at all.

Sensitivity Measurements - Update

I had the opportunity to measure the LW and MW sensitivity of the Elad FDM-S2 today. Hence, the Sensitivity Figures on Some Receivers doc has been updated. Spoiler: It's a sensitive radio. Thanks TJ Bråtveit for lending me the device.

QSL: WXME Monticello ME 780

WXME was heard with a fair signal, actually better than WBBM, at Smøla island in early November 2018. What prompted me to send a report was actually a BBC World Service feature about pirate radio in New York City - in fact a very interesting program in which WXME owner Allan Weiner was interviewed. WXME is co-located with SW broadcaster WBCQ, also owned by Allan. He sent a very prompt response to my report.

Lacking a WXME logo, here is the SW antenna as displayed on the WBCQ home page. US station #1100 (excluding Hawaii).

Power Your SDR From a USB-C Port

It has become common to power SDRs that need separate 5V power from a PC USB port. However, there are limits to how much current a USB port can deliver. The RFSpace Cloud-IQ can - barely - cope with a USB 2.0 port. It is best served with a USB 3.0 port, because USB 3.0 can deliver almost 1A of current while the USB 2.0 is limited to around 0.5A. The Perseus definitely needs USB 3.0.

But other SDRs need more! The RFSpace NetSDR and the KiwiSDR need more than 1A. Enter USB 3.1 with type-C connector. New laptops are usually equipped with one USB-C port, hence it should be possible to power these devices from a laptop. Next on the list was finding a USB-C to 2.5mm pigtail. Finally I found some on eBay and ordered from two different sellers.

I was quite surprised when I got the first batch and tested them via a DVM from a USB-C port on my Latitude laptop. No voltage! Long story cut short: Check if the PC actually delivers current through the USB-C port! So what to do next? Last year I bought a 20A/75Wh Li-Ion battery, also known as "Power bank", with two USB-A and one USB-C outputs. Capacity is 2.4A. I'm mostly charging my mobile phone and headphones with it. But why not power an SDR from a battery?

So, moment of truth: Would the USB-C port on my power bank power up the NetSDR? Indeed it did! And noise-free at that. The powerbank allows pass-through charging, so a noise-free 5V power supply on the charging end should enable continous powering of three SDRs with this battery. Well, at least in theory, as long as the drain isn't larger than the charge.

The coming summer I will receive a much larger powerbank and a high-capacity charger. Potentially capable of powering six SDRs.

But the real novelty is if your laptop's USB-C output can deliver the necessary current.
But always, always, always remember to check polarity when you buy no-name cables or adapters from unknown eBay sellers. And others for that matter. A fried SDR is not a pretty sight.

QSL: WION Ionia MI 1430

I noted in a Facebook post last week that the Chief Engineer at WION would be running equipment tests on daytime power after Midnight EST on Sunday. Testing included a 1000 Hz tone at different levels and lengths.

So! Propagation was good, and from 05:35Z onwards I noted the 1000 Hz tone as it was switched on an off, and at low and high levels. The details were sent off together with a video link to the station. Today, the CE emailed a confirmation of my reception.

I heard and recorded the station with Perseus and Jaguar software, but used HDSDR to get a better view of the 1000 Hz tone. The illustration below shows the tone at peak levels right after being switched  on.

Please note: This was NOT a DX Test, hence not widely announced.

Verie #20 from North America on 1430.

QSL: KPHI Honolulu HI 1130

Several years ago, KPHI was heard with a decent signal at my Kongsfjord location. No replies though. A recent response to Patrik Willför prompted me to send another report to the station, which replied within hours. Thanks PW for v/s info! They are listed at 1 kW, but current power level is 800 watts.

31 out of 31 heard Hawaii stations now confirmed.

QSL: WURN Miami FL 1040

Actualidad 1040 AM (Un idioma, Todos los acentos, Una sola señal) was heard with a fair signal on Dec 28 at the Smøla location. It took a while before the reply came, but a very friendly email arrived today.

WURN is a little high in frequency, so quite easy to detect with the Jaguar software: 1040.022.

QSL: WAMC Albany NY 1400

The second part of December was good for MW DX-ers, and on the 23rd I heard a fair signal from WAMC, mixing with CBC Newfoundland, at the Smøla location. It took a while to get the report sent off but I received a very swift and very friendly response.

Friday, January 18, 2019

QSL: KFPT Clovis CA 790

KFPT "The Deuce" was one of several interesting stations heard on Jan 14, although it was also heard last October. A friendly email response came yesterday. KFPT belongs to One Putt Broadcasting, which also owns KFIG Fresno 940 and KYNO Fresno 1430. 940 is heard at regular intervals, 1430 not so since their main lobe points away from us. But one day!

Thursday, January 17, 2019

QSL: WCMP Pine City MN 1350

Like with KAWL below, WCMP was heard on January 14 quite late in the day, but it was also heard last October. A short email today confirmed my reception.

QSL: KAWL York NE 1370

We had some very interesting conditions on January 14, both before noon and after. KAWL came in very late in the day. As always, the Director of Engineering at Nebraska Rural Radio Assn. sent an exemplary response in the form of a pdf QSL.

Monday, January 14, 2019

QSL: KNSP Staples MN 1430

Today provided some very interesting spot conditions, one period favoured the Minnesota area with several rarely heard stations with excellent signal strengths. And KNSP, which was new to me. Swift email response this evening. The verie signer has previously confirmed KWAD-920 and KKIN-930 for me.

Wednesday, January 09, 2019

QSLs: KROE 930 and KWYO 1410, Sheridan WY

Last weekend these stations were heard at the same time, KWYO quite good, KROE somewhat weak but legible. Friendly email this evening confirmed both. From what I understand, they share the same tower in Sheridan, and are co-owned by Sheridan Media. KWYO was my 20th verie on 1410.

QSL: CFSX Stephenville NL 870

I've been wanting this last, unheard VOCM network station for quite some time. With only 500 watts, and strong competition from WWL and Cuba's Reloj, it's not been easy. On Jan 3 it was audible for a couple of minutes, mostly music, but a reference to VOCM news at the end solved it. Since it was running in parallel to VOCM 590 I sent off a video recording to VOCM to prove I was not cheating, and got a very friendly response: "It took some tweaking using our Adobe Audition sound editing program to clean up the audio, but I could actually hear the female voice and the reference to Kento."

QSL: WNWC Sun Prairie WI 1190

I heard WNWC with a weak signal back in 2012, but the response I got wasn't conclusive. However, in late December it was heard with a very good signal during a daytime opening (thanks, OJ), and I sent off another report. Friendly response from the local Sun Prairie engineer today.
