Prepared For Remote DX
New radio, new antenna. Connected to the PC by wire; the speed was as advertised, 2000/500 kbps. Tried to put up a wireless router. No connection. Being rather inexperienced with configuring routers (all previous routers I've had were plug and play), I spent quite a few hours trying to set things right.
This afternoon, a day and a half from going away, I got it working. At the time of writing I am remote controlling my Scaleo PC where two SDR-IQs and one Perseus are demodulating with no problems. A "pro" licence from Logmein has enabled me to have audio from the Scaleo to whatever PC I choose to work from. So, unless we have a power-down or the broadband goes down I should be able to listen to Kongsfjord from my Christmas location in the Lofoten islands.
The Scaleo has 3 GB RAM and a 6400 AMD processor; CPU usage is typically 75-85% with peaks around 90% when all three SDRs are demodulating.

More Perseus Sensitivity Measurements
But I got my measurements, didn't I? Indeed I did and they show a uniform -102 to -103 dBm sensitivity in AM, 6 kHz bw, 30% modulation with AGC off. Preselector, Preamp and Dither were all on. When I switched Preselector off, sensitivity increased a couple of dB, typically -103 to -105 dBm. While the Perseus (or the SDR-IQs) doesn't match my Icoms which have levels around -111 to -113 dBm, it should cope well even when DX-ing at very low signal levels once a high-quality preamplifier has been set in front of it.
I tried to remove the Loran C notch filter to see how the Perseus coped with it. Same result as with the IQs: Severe overloading on MW. But I hadn't expected otherwise.
Anyone Looking For An Eton E1XM?
With three SDRs in my radio room (2 x SDR-IQ + 1 Perseus), I just need to cut down on the number of conventional receivers. I sold my Icom IC-7000 a few months ago, and I have decided to sell my E1. That would leave me with 2 x IC-746Pro and one IC-703, all three specially modified for MW DX by Dallas Lankford. It is not likely that any of them will ever go.
My E1 is of the "refurbished" stock - Eton did a recall because of a missing trace in the circuit which could cause battery heat-up if the user was using both an AC adapter and batteries. The issue was dealt with by Drake according to web sources. I bought it from a US dealer who filed for bankruptcy the following day. Hopefully there is no connection there... I believe there is a tag or sticker inside confirming that it has been repaired.
The E1 is a very fine receiver indeed and very sensitive (0.5uV in AM, 7 kHz, 30% mod) and with very good selectivity and the possibility of using AM Synchronous Detection with the Lower, Upper or both sidebands.
My E1 has been exceptionally well kept even if it has many hours in the "On"-position. There has never been a battery in it. Original box. I was thinking EUR 300 or equivalent + shipping. The price would probably exclude North Americans because of the poor USD-EUR exchange rate, but the E1 is much higher priced in Europe so this should be a bargain for most European DX-ers! I'll throw in the correct AM antenna connector. Electronic bank transfer to my IBAN is the only option for payment.
For another EUR 50 I'll throw in an iriver flash-based MP3 recorder/player with a dedicated line-in (very few have these days). These are excellent recorders with a recording level adjustment, and using 64 kbps gives you 32 hours of DX which can be dragged and dropped to your PC's hard drive (full UMS compliance). Powered by one AA-battery. 1 GB.

Another interesting facet of using SDRs like the IQ, SDR-14, Perseus etc: The spectrum you record can not only be DX-ed, but actually enjoyed, during playback. You never have time to do that in a DX session.

SDR Sensitivity Measurements
Who knows. Very few people find it interesting or worthwhile to measure a radio's sensitivity. But then very few people own a signal generator which is what you need to do the job. Neither RF Space (SDR-IQ) nor Microtelecom (Perseus) have officially available AM sensitivity data. Instead they have MDS numbers for CW and SSB. The Perseus claims an MDS of -131 dBm in CW, 500 Hz bandwidth, and -124 dBm in SSB, 2.4 kHz bandwidth. Similar data for the SDR-IQ is -127 dBm in CW, 500 Hz bandwidth (no data given for SSB). So in theory (because I think these are calculated figures, not measured), 4 dB advantage Perseus.
There is no substitute for measurements though. I know of two AM sensitivity measurements on the SDR-IQ, mine and Dallas Lankford's. We both got -102 dBm or 1.8uV. Nico Palermo calculated the Perseus AM sensitivity for me to -102 dBm. A measurement will probably end up in that range, possibly 1-3 dB lower if my ears heard correctly. I believe that a correct Perseus sensitivity measurement will soon be done by Dallas Lankford.
Still, numbers, be they calculated or measured, will never replace real-world experience. I have yet to compare the two SDRs enough to declare a winner, and I'm not sure I want to put one ahead of the other anyway. It is highly unlikely that I will be able to hear a station on one radio that I can't hear on the other. That said, the Perseus appears to have AM bandwidth configuration options available that will dwarf most if not all other radios.

Some More Perseus Impressions
RF recording should be easier with the Perseus than with the SDR-IQ but isn't. The problem is that you have to name a file before it starts recording, so there is a dialogue box to pass just like with the SDR-IQ. Playback is also more cumbersome than with the IQ since you can't start playback in a specific point in the file. You don't know where you are until you've selected the point. And you can't jump back and forth in the file; you need to highlight a period of your own choice (except you don't know how long it is and when it starts) and play that period. It automatically loops though and that's a good thing. When playing though, the program keeps track of the time.
Also I miss the option to tune via the up/down keys and left/right keys. And when you use the mouse, scrolling forward in Perseus means decreasing frequency while in the IQ it means increasing frequency. So operating the IQ and the Perseus at the same time can be a bit confusing.
I also experienced a couple of crashes; one resulted in the need of a reboot before I could start the software again. Maybe it's a Vista issue. I also hoped that the AVG settings chosen at one session were saved and used again in the new session; apparently they are not.
The AGC settings (there are four; Fast, Med, Slow and Off) seem well chosen, but I would have preferred to have the option of determining the values of each setting.
And horisontal lines on the display with dBm values would have been great.
The above might indicate that I'm not satisfied with the Perseus. That is not the case. As stated earlier, the audio quality excels, and the bandwidth option is exceptional. And some of my issues could be because I haven't explored all possibilities yet.
Oh, and one last thing, and an important one: The switching PSU. It is not as quiet as I thought. It actually produced tones every 8 kHz, not in the Perseus, but in the IQ! I had it placed in a 4-way mains socket which also sent current to the splitter they were connected to. When I placed the PSU in a different socket the noise seemed to go away, or at least be greatly reduced. But I really want a stabilised PSU for my Perseus.

The Perseus Has Landed
Sent from ssb.de on Dec. 4, arrived today. Yes I agree, the picture is NOT good... but the radio is. I tested it only briefly in Kongsfjord this afternoon. Compared to the SDR-IQ it appears to have better audio recovery, especially in AM mode. Tuning takes a bit getting used to, accustomed as I am with the IQ and Spectravue. The driver and the XP software installed without problems on my Vista PC.
For some reason I was unable to make a sensitivity measurement of it. Don't know what I did wrong. There is no reason to believe that it is less sensitive than the IQ. I didn't find any threshold signals where I could compare the two properly. But the Perseus appears, from the 30 minutes I played with it, to be an excellent receiver. And surprisingly enough very immune to the Loran C noise I usually hear in the 550-590 kHz area. And as many have pointed out: The adjustable bandwidth control is superb. Very slick.

Logs From October 24
I've tried to put log tables on the blog before, with modest success as it seems that blogger.com does not display tables very well whether they come from word processors or spreadsheets. So I've decided to use Google Docs, which means that when you click the link, you will be redirected to a look-only version of a spreadsheet. Initial tries indicate that this should work well.
All ID'ed stations are listed (so the list is quite long, with many stations of little interest). Some frequencies were not checked out much, like 670, 680, 770 and others.
It is interesting to note however, that at a different location in Northern Norway (Andøya), the AND1 crew were having great signals from the New England states while westerly located stations dominated here.

KVOL Lafayette LA 1330 Verification
Coolest catch from North America on my part so far this season is KVOL, a 1000-watt station with a very modest lobe to the north. It just suddenly popped up at 0731 on October 24 with "We are the voice of Lafayette, 1330 AM KVOL"; faded down and was never heard again. Operations Manager Charles Sagona emailed me a verie this evening, informing me that mine was the second of two reports this year; the other came from Finland.
I'd never have caught it without the SDR-IQ.

Strange Conditions Pt. II
4QD 1548 had a super signal later on and we thought we might have another good Aussie opening, but only found traces of audio on 630 and 1512. The most common Pacific stations like Tonga 1017 and Marshall Islands 1098 were also present but not with impressive strengths.
On Monday evening I was called up by Chris Walker at CBC British Columbia, and we had a five-minute chat which was aired on CBC Daybreak North which originates from Prince Rupert (860) and Prince George (FM). The interview ended with Chris giving me an official verification of my reception of CFPR Prince Rupert BC 860, on the air! My first!

Strange Conditions
Night: Nada
Late night: Nada
Morning: Getting better
Late morning: Better!! Stations like KRTA-610 and KPDQ-800 visited us along with many WA and OR stations. Kinda saved the day. Nothing exciting from Asia or the Pacific, and excessive noise on the easterly directed beverages.
It was sort of depressing to sit here during the night and have SMS after SMS from the Andøya gang reporting excellent DX. While there are always local differences that can vary over hours and days, I think it is quite obvious that the western, coastal locations of the Vesterålen (in the case of Andøya) and Lofoten islands are superb locations for trans-atlantic DX. About time they are tested.
I had a bit of time to do other things than DX as well. Olav Skår from Stavanger, who visited us a few days ago, left an Icom IC-R1500 receiver for me to test. I did some measurement tests, and tried to find out how it could work as a MW DX receiver. A quick conclusion on the latter issue is that it won't. The user interface may be good for scanning, but not for MW DX. It is simply too cumbersome to operate, whether you use the software interface or the remote control. I thought that it was very unsensitive on MW - well it is but not as bad as I had thought with sensitivity figures in the -96dBm range or around 4 uV. On shortwave sensitivity is around 1 uV. I assume that it has a 10 dB attenuation pad built in, which probably can be removed, if the receiver could work well otherwise. I'll spend more time with it though and make a write-up.
Weather: Still mild with 5C, and still windy, SW winds at around 40 km/h.

Things To Do When Conditions Should Be Improving
2. Check antenna connections
3. Re-check antenna connections
4. Shake heads
5. Twist the dials
etc....
Seriously though: According to SWPC, conditions should be good now. But as is often the case in northern locations, the signals take time to recover. Not that it seemed to play much difference at Andøya, where our friends Jan, Ole, Geir and Tore had superb conditions towards Latin America last night. Only few, and mostly weak, signals here. Maybe someone fired off a rocket from the Andøya Rocket Range and put a hole in the ionosphere so that the signals leaked down through that hole?
Nothing much from North America either, very quiet on the band. But then the ionosphere again acts in mysterious ways as KSMA Santa Maria CA suddenly appeared on 1240 with a good signal! Just about alone! But followed by the more common KTIX Pendleton OR seconds later. Again and again we see that even when conditions appear totally useless, excellent DX can be heard.
Here is the latest weather update: Very mild and calm during the night, increased wind and a little rain at the time of writing, but still very mild with around 5C.

Things To Do When Conditions Are Poor
2. Jog. With 60 km/h winds only OJ is brave enough to try, and he will surely break the Veines Lighthouse world record - on the way out. He will surely crawl the way in.
3. Write reception logs and reports. We will try to use Google Docs as a mean to coordinate our efforts.
4. Listen to KBRW. Now and then they put a volunteer behind the mic who is more interested in playing a heavy-metal/death-metal mix than put his voice on the air for any talent hunters to hear. Maybe just as well. But we do like the music!
5. Make up for lost sleep. Arnstein slept 12 hours during the last 15 hours, roughly the same as during the first week.
6. Wait for Kongsfjord Gjestehus to open their doors for us.

Friendly email from Chris Walker today confirmed my reception, making it my first KONG17 verification.
Otherwise, conditions have been very much on-off today, though mostly off due to the coronal hole. See the kongsfjord.no update for details.
Very strong winds today didn't prevent me and OJ from making a 7 km jog out to the Veines lighthouse. During the evening and the king crab meal it calmed to around 37 km/h and weather will improve further during the night although the temperature is around 0C.

KONG17 Update, Wednesday
The kongsfjord.no updates should speak for themselves so I need not make the same listing here. Yesterday was the best New Zealand day that far. Today topped that with a good margin. With 900 watt stations and both islands being heard, we now know that even for such an elusive target there really is no limit.
Conditions towards Asia are still quite good but after such an ordeal it is difficult to find motivation for DX-ing more common countries and stations. Preparing tonight's dinner: Reindeer cirloins with cloudberries and cream for dessert. We're hoping for at least another night and another morning with good NZ conditions before the effects of the Coronal Hole hit us.
Weather update: Dead calm today after a windy evening and night; very light drizzle and still around 6C.

Still Waiting
From around 0500 mostly prairie-type conditions with strong Canadians from Manitoba and westwards, some Mexico and signals on every channel but mostly heard before. So: Still waiting. But as I write this, CJRJ Victoria BC 1200 is entertaining us with Indian music at excellent strength. Hopefully we will enjoy better conditions towards the Pacific today.
IBOC noise: As reported from the Lemmenjoki expeditions, the IBOC noise is very much noticeable, and obscures reception on several frequencies.
Weather: Cloudy but dry, 35 km/h wind from the south and the temperature is at the freezing point.
Will upload some pictures later today.

The Kongsfjord Spider Web
Here are my beverage antennas:
1: 30 degrees, 610 meters. Aimed mainly at eastern Pacific (from NZ eastwards), very good for Hawaii, Alaska too.
2: 58 degrees, 550 meters. Aimed mainly at Japan, eastern Australia, Guam
3: 85 degrees, 600 meters. Aimed mainly at SE Asia; Australia. The back lobe hears Brazil and Argentina well.
4: 315 degrees, 220 meters (old). Aimed mainly at eastern North America, also good towards Mexico and northern South America.
5: 315 degrees, 470 meters (new). This is a back lobe beverage. Otherwise same as 4 but more gain. Also more EU interference so sometimes the old 315 provides better SNR.
6: 340 degrees, 350 meters. New; replaces the old 333 degrees, 290 meters beverage. Aimed mainly at western North America.
Average height above ground is 2.5 meters.
Beverages 4 and 6 start roughly at the same spot. You will note from the map that beverages 2 and 3 go quite high in elevation and have some steep climbs. Apparently without compromising directivity too much (or at all). Altitude displayed in meters.
Luckily my neighbours have a very laid back attitude towards my antenna farm...

Good Afternoon For Australia
1161 5AN ABC Naracoorte, SA
1233 2NC ABC Newcastle, NSW
1503 2BS Bathurst, NSW
1512 2RN ABC Newcastle, NSW
1548 4QD ABC Emerald, QLD
Some hefty signals later on x-band too, especially 1638. I also heard Japanese on 1650 which puzzled me a bit since all the Japanese low-power coastal stations are listed on 1670.

Recent Developments (And The 475-meter Was Not A Dud)
Fair conditions towards North America although I haven't had too much time to listen, and the IQ-recorded material hasn't been checked yet. Interesting though that the 475-metre beverage antenna which was said to be a dud in a previous post, certainly isn't! Yes, interference levels from Europe and the Middle East was hard to beat, but after dawn when the signal levels dropped the antenna proved to be an excellent performer. North America signal levels at least 10dB better than the old beverage. The picture shows the first 150 meter run; you can see where it climbs up on the cliff and continues at a higher altitude.
I will keep the old, short one though since it enables DX at nighttime with its excellent rejection of EU/ME signals.
The 5th beverage is now up, a 330-meter directed at 333 degrees or western North America. Only one waiting, the 600-meter directed at 30 degrees (Pacific).
Finally, I finished an AELPAF (see description), and connected it to my audio distribution and a large Tandberg vintage speaker. Excellent audio and rejection of selective fading distortion!

A 475-metre Dud
Erecting it was an ordeal... through difficult terrain. But after many hours outdoor I had managed to get a very straight, no-sagging beverage. Time for testing. The "old" beverage was up so with the help of my two SDR-IQs I could make direct comparisons.
Well, the new one did bring increased signal levels on North American carriers. 4-6dB, which is not bad, but I had hoped for more. However, signals from the other end just about exploded with 15 to 25dB higher levels! So, instead of an improvement I got a 10 to 20dB worse SNR!! One notable example is my North America indicator station NRK Longyearbyen, Svalbard 1485. On the old antenna I had a strong, clean signal. On the new one the signal was stronger, but audio was distorted from several interfering stations.
Sooo.... longer is not always better.

Aussie Season Begins!
Nothing noteworthy on Australia x-band.
I have set the two SDR-IQs to record an hour each tomorrow from 1830 UTC onwards, covering 531 to 918 kHz.

Summer At The KONG DX Site
Not much to report these days, except I still test out the SDR-IQs with my ALA-100 large circumference loop. Above a picture of my DX location taken on July 1 at 2100 local; the view is due East. Lots of meadow buttercups and green grass form a nice colour balance with the blue house. Still snow on the distant plains, altitude 300-400 meters. To the right you see part of the house of the nearest neighbour. Not much RF noise to worry about from that end...
