As usual, I cannot resist the temptation to write about the receivers I have. Some initial impressions have been posted earlier in this blog. You will find a more detailed report in the Links section, or here. Comments are appreciated.
Anything of interest heard last night/morning? I was checking the band at 02:30 and 04:30 UTC here in Vardø this morning, but it was remarkably quiet...
Hi Bjarne, What about stability? I use a Perseus and that SDR takes at least 20-25 minutes to get warm and stable. To maintain high resolution you need to recalibrate quite often. Dare I ask for a small comparison of + and - for the SDRs used? 73 Thomas Nilsson
I have the same problem with Excalibur G31DDC. Frequency stability is not very good. It takes half an hour minimum until the frequency stops drifting away. This is nasty when receiving AM synchronous or SSB etc. as you have to retune continuously. G33DDC according to specs should be better. But is this worth double the price?
I haven't had any stability problems with neither the G31 nor the G33. But then the receivers are on more or less 24/7. To Hector's question: I don't know what other changes/improvements will be in a future software update, but my main concern was that the DDC spectrum moved during recording if I was tuning. It will now be possible to keep the DDC spectrum in fixed position for those who want that. Thomas: I tried to do that in the G31 post a year or so ago. It's a difficult undertaking because my preferences may be different from other people's preferences.

Hi Bjarne and gang!

73!
Only the most common stations, Hans.

Hi Bjarne,
What improvements between 161 and 166?
