Dear all. I had a phone call from an amateur who is convinced that he heard a high-speed machine-sent morse transmission on March 19th. The message was "WBF WX" repeated, and the frequency was betwee
Dear all. My TS850 has broken. There is something wrong with the synth. It has gone extremely deaf and, when tuning into a strong AM signal it has a strong tone superimposed upon it. The tone will be
Dear all. I will be in GM again from Sunday evening for a couple of days (without the TS850....). I will try some QRS in the evenings. Usual frequency 137.72kHz. 73, Dave G3YXM.
Dear all. GI3PDN and MI0AYZ (who has a NOV for 73k) intend to operate from a disused Decca site Friday and Saturday. Skeds welcome on both bands. Ray's mobile phone number is 07787 153 137. There wil
Dear all. I have fixed the TS850 so should be able to hear the DX again.... noise permitting! The fault was one of the DDS chips on the "CAR" unit, the one that produces the mix frequency from 8.8MHz
The only thing worse than a poor cw operator is someone fumbling on a keyboard with 2 fingers!!!!!!!!!! Bother! That's me stuffed on both counts...... Dave G3YXM.
John. What about telling us how to do it - I refer to 64 pin Surface Mount Devices? I had the advantage of a quick "course" on surface-mount installation by a sales rep for a soldering-iron company!
Marc. Very bad static here also. Sorry, no signals heard. 73. Dave G3YXM. Hi all, More QRN this week. (59+20) Sunday morning I can't receive any station. I'll repeat this test with more power and a 1
Rik et al Some weeks ago someone (G3YXM ?) reported hearing CW arround 80kHz. It was actually reported to me as approx 91kHz, possibly sending "WBF WX" repeatedly, so maybe not the same station. 73.
Dick and all. Very puzzling! I worked Jim straight after you and found exactly the opposite..... 4dB better on the "small" antenna. We tried the test twice and I continued to listen, each time it was
Dear all. Jim M0BMU/P is at Puckeridge Decca station this weekend and will be calling on 71.7kHz normal CW with 1W erp tomorow morning (Sunday) between 0900 and 1000 utc. He will listen on the 136kHz
Dear all. Being a topband mobileer for many years I am used to using antennas that are a tiny fraction of a wavelength. From an experiment I once did to try to improve \"sky-wave\" from the whip, I c
Yes I noticed that... Looks like sawteeth on Spectrogram but in little steps rather than smooth drift. About S7 here. Dave G3YXM Tune to 137.60kHz and use Spectran set at Resolution 0.125Hz and speed
Andy et al. Some screenshots are at http://www.picks.f9.co.uk/newspic22.htm I left the bandwidth at 0.12 and slowed down the scan for the 5Hz version and it still looks cleaner than the 10Hz. Dave G3
Andy. I did run Spectran at 0.086? setting and could plainly see the signal but far too stretched out due to my speed setting being too fast. As it had taken about an hour to build it up I didn't try
Dear all. Finbar EI0CF will be running his QRP beacon on 137.760 (now crystal controlled so no drifting!) over the next few days. Very useful if you're doing RX tests over the holiday. I don't know w
Dear all. From Dave G3YXM. I pass this message from Richard to the group..... I was on my LF site during this saturday, but I burn all my mosfets. Something is wrong with my power amplifier. After a
Towers transistor selector has it as: NPN, Si, TO3, 300V Vce, 15A max, 175W dis, Hfe of 8 at 10A, Ft of 15MHz. Made by RCA originally. Sounds a useful device. FETs are better though! 73. Dave G3YXM.
Larry, Bill etc. I have been on since 1930 on 135.9236 ( Black Star accuracy!), just about 1 Hz HF of Jim M0BMU. I cant see any other signals from this side at present. Will stay on until about 2200.
