Dear Alan, LF Group, Loran A while ago, I had a problem with a weak FSK signal around 137.4kHz - it turned out to be a 3rd order intermod between the "DCF" stations on 138.83 and 128.93, and DDH47 o
QRN is just wiping the band out completely but did manage to hear PA3DZ something could not stay around any longer to get the last letter. Testing on normal hand speed CW but on visual completely wip
System now complete and working with both QRSS and hand speed Morse. Antenna current around 1.5A with coil in shack. Should be better when I get it into its own Box outside but in the meantime is an
Thanks to all that responded with info about the QQZ06-40 tube. The tube does have gold plated pins as opposed to the QQV06-40 with normal pins. It looks like the heater voltage is 2.1 volts and not
Hi All Does anyone have tech info for tube Mullard QZ06-40A, similar to the QV06-40A but does the Z indicate a different heater voltage? 73 de Mal/G3KEV
Hello group, I am about to put up a transmitting loop antenna. Dimensions will be 23m long and 15m high. Thanks to Dick (PA0SE) I could achieve a wheel of 7mm litz wire, so wire losses should be min
I got a weird error message when trying to install it on my P166 laptop with Win95 OSR2. V.128 works fine on it. Its my P166 laptop that seems to give most trouble with Argo. The computer is a Compa
HI All Reference feedback about the new release. I find it runs using win95 and win 98 on 166 mhz machines with 32 kb mem but suffers from the same problems as before, after a varying time from about
Hi All My argument is that a vertical antenna has the advantage over a loop at the same height out in the open ie the middle of a field. Some others are discussing environmental issues like verticals
Peter, reasonably reasonable the same site to a That was also the 'collective wisdom' amongst Lowfers in the US, until 3 years ago. The Wisdom was based on 'cut and try' and "how am I coming in?" ty
is Dear Mike, LF group, What frequency is it for? Surely not LF - at 185kHz, the voltage rating might be a problem - about 340kV with 40A! This is what I have been saying all along about loops and p
Hi All One stn heard this morning, G3AQC on 73.76 khz 559 at 0908 utc. Using a 90 metre vertical loop resonant on 73 khz but not optimum for his direction, broadside to the signal. No other signals h
This is an automatic response to confirm receipt of your e-mail. Hi Merv You would need to sort your auto responder out because there are more messages from it than anything else on this reflector!!
Hi Bob Nothing of importance seen this morning. At 0708 z a couple of dits and a dash, maybe you were tuning up, most likely some qrm on the freq.Will look again around 1700 z 73 and gl de Mal/G3KEV
Hi Bob /ZL2CA I have sent you a shot of acty taken on your freq, direct because its too big for the reflector. See what you make of it. The freq is correct and the shift looks right and the time is a
HI Bob I was able to copy a fsk signal about 1712 utc with a shift of around 0.5 hz were you transmitting at that time. I had the signal some 15 minutes before that time. I had to go out and when I c
