Hi Jim, Sorry, I couldn't be QRV last night. Regarding power levels : On a second thought it is OK for me if you run high power for the TA test. I can reduce your SRN by receiving on a short piece of
Congrats to John and Jim on this accomplishment. I'd like to also point out that this successful reception took place on what, the first or second night of transmissions ? And in the middle of March!
CFH has been on fairly reliably during the week and is often visible in daytime. This seems to be the result of some disturbance and there are signs of what I think is multipath fading during the nig
I wasn't aware of Jim's BPSK tests on saturday, but as I heard a 'suspicious signal' in the digtal mode segment I decided to record a 1 minute WAV file and let WOLF have a try on it. Result : a 100%
Hello Mike, So far I didn't get any similar error reports of 'mixing up' characters. Any chance that you selected DFCW mode instead of QRSS ? If you select DFCW and transmit without applying a freque
Hello Jim, I just downloaded the WOLF software. I'll try to get it running during the weekend, I will let you know when I can receive WOLF. You're 599+ with 1 Watt ERP so I'd prefer something in the
Hi Andy, A pity, I threw away some old VMP4 devices only a few weeks ago in a clear out of ancient and obsolete semiconductors as part of teh shack rebuild, they would have been quite good for an act

Hello Jim & group, Excellent paper from Jim, it seems a good starting point for an open discussion. One of the point that Jim mentions is the duration of a QSO. While making the recent changes on QRS
CW (by ear) -18db below the noise QRSS (3 sec dots) -27db below the noise QRSS(S) (60 sec dots) -31db below the noise WOLF -40db below the noise ... The above figures seem a bit strange to me : QRSS
Hello all, I have a new version of QRS available that is adapted to the recent needs for longer dotlengths with more accurate timing. New features : - dotlengths up to 1 hour (OK, very long ... but I

Have heard OK1DTN for the last 2 weeks several times with good signals, from 559 up to 589. But so far I always called him in vain. Most of the time he has a fair amount of QSB on his signal (compare

Hi David, did you test the MAV11 on 136kHz ? Mini-Circuits gives a frequency range of 50-1000MHz (while the MAR, ERA, RAM series start at DC), so it may have a internal C that limits the lowest frequ

Hello Laurie, In most circumstances SNR will be determined by the 'band noise' (QRM - QRN), so the noise figure of a pre-amp won't matter too much (anything below 10dB should be fine). But, unless yo
