..................... One such candidate could be the Steve Onley's FDK. I know that, theoretically, PSK can have an advantage over non-coherent FSK, but this doesn't take into account phase distorti
You may not need to. There's hope for us low ERP guys yet, it seems that one just needs to go slower and slower. What about 300 second dots or 1000 second dots for VK and ZL? 73, John, G4CNN There's
I think I got some signals when monitoring 135.920. I set up Argo to watch from 800Hz (135920) to 806Hz (135926), 60 second dot, slow. I'm not shure but is there any freq alocation table (who's where
On Sunday I increased the inductance at the top of my mast. I replaced 3mH of Litz wire with 7mH of ordinary wire. This made the antenna almost self-resonant. In fact, I needed a 6800pF capacitor (ve
I have been giving some thought to whether I personally regard the recent G3LDO/VE1ZJ/VE1ZZ QSO to be a two-way. My initial reaction was to say that because there was a relay station that did more th

About QSO format. I have been operating EME for 11 years now . The criterion for a qso has always been the TMO system plus appropriate RRRs plus complete exchange of calls. I feel we should use the s
.......................I suggest the time has come to make this a requirement for all of us experimenting on LF. Comments etc. Larry VA3LK I am sure you meant to say recommendation. As soon as we mak
It has been pointed out, quite correctly, that the ARRL story about LF operating has errors in it. In defense of my fellow journalists, I will say that given limited resources it is inevitable that s
Hello everyone. A simple query to give us all a rest from the hi-tech stuff. I've been listening on 137 for a year or so and in that time I have NEVER seen any Loran lines. People tell me that if I
Mike, If you were on 135.92375 I may not see you due to a continuous signal I have there close to .9237. Several times I have suspected there was a QRSS signal maybe .05 hz above this line. I will up
A second signal on 135.9226 was showing up occasionally, with best copy also around 0300 UT. Anyone want to own up to this signal? Dex, I made Jim's signal exactly 135.923 and I transmitted 'XDV' all
So far QRS allows up to 65 seconds 'element length'. Reason for this is that the dotlength is calculated in multiples of 0.1 second and are handled as WORD values (2 byte). At the time I released thi
As much as I hate to say it, that probably was not the AMRAD beacon. It is really at about 136.745 (we are assigned 136.750 but the tolerance specified allows us a few HZ either side). Also I watched
I cannot measure the frequency with a accuracy more than +-1Hz, so any report about it is welcome. '73 IK5ZPV, JN53KX Valerio Valerio, Are you using Argo? If so, you can measure your frequency much b
The signal was visible from about 22.00 last night (010205) until 06.00 this morning when it died out. I saw no clear "Dawn effect" on the QRN in these images, but the QRN is low throughout, which mi
Absolutely, we can transmit at any speed we want The only limitation would be the ON7YD QRS program: does it allow us to go slower? (I cannot remember its parameters, and the actual software is at th
For more than one year now, we have had a QRS beacon on the air 24/7 (at least, weather permitting) but our presnt "Part 5" license only allows us to transmit on 136.750 +/- 5 Hz. Our beacon is being
Thanks to Markus, DF6NM, and John, VE1ZJ, for their spectrograms of last Saturday night's transatlantic tests. I am particularly grateful as it appears from careful analysis of the pics that my signa
