Hi Guys, I moved my loading coil yesterday and the ground loss dropped from 103 ohms to 91 ohms. That is 12 ohms removed at a stroke! Previously it had stood in a corner of the patio by a wooden open
Hi Rich, If you publish a schedule especially for QRSS (with params) with times and exact frequencies for next weekend, I will certainly listen and who knows we might even make a QSO. 73, John, G4CNN
Hi John, 60kHz is probably US WWV transmission. 65.8 MSK heard here. 68 Rugby 72.5 not heard here 73.6 RTTY heard here 75 HBG, Frangins, Swiss 77.5 DCF77, Mainflingen 81 GYN2, London In this range, w
Hi Tom, Steve, I heard the tail-end of that, though Steve was only just audible here. Would be interested to know what you were running Steve? 73, John _______________________________________________
Hi All, Congrats to Bob (G8RW) and Jeff (F6BWO) on finally completing a QSO this morning. Jeff persisted in calling Bob, although Bob couldn't hear for a long time and finally they made it first with
Hi John, I have often heard the RTTY mark 73.56, space 73.64kHz, but it is not there this morning 010601 at 09.28, only the Rugby RTTY at 73.4, which is good clean RTTY at present. John, G4CNN ______
Hi Andy, I guess the line: So EIRP of Tx = (Watts / m^2)* 4.PI.R^2 = E^2 / 4 * PI * R^2 should read:(?) So EIRP of Tx = (Watts / m^2)* 4.PI.R^2 = E^2 /377* 4 * PI * R^2 John, G4CNN __________________
Hi Alberto, I too noticed the frequency was not spot on and it increased a little at start-up, but this is perhaps not surprising when you bear in mind the means of generation and its age. In fact I
Sorry Fabian, I had planned to listen, but some urgent QRL came up and I was unable to. So no report today. Please continue with your transmissions. Next week I expect to be able to listen regularly.
Hi Walter again, If you class it as data, you can use frequencies above 137.1 to keep in with the INFORMAL band plan. 73, John, G4CNN _______________________________________________________ http://in
Hi Walter, I thought it was some new type of data transmission, which I always find intriguing. My ERP calculated from reports and the formula Dick, PA0SE, gave some time ago is at most a few milliwa
Hi John, That is it! Your picture shows exactly what I see on 73.3kHz. It is not RTTY but 100Hz wide FSK centred on 73.25. You evidently have a very good antenna for this direction. I would very much
This is really one for the record books! It certainly justifies the retention of 73kHz and even the professionals are probably learning something from it. The chances of making it from ZL to EU havin
Hi Everyone, I have heard OK1DTN regularly during this week. Is this a consequence of improved conditions or is Ruda running high power or perhaps has a better antenna than most? Otherwise the band h
Hi Peter, There is a Litz Wire Guide on the site of WireTronic Inc. at http://www.wiretron.com, which describes the notation used and lists standard types. 73, John, G4CNN ___________________________
Hi Marco, It's called Chaika (or as you would probably spell it Chajka) Seagull. John, G4CNN _______________________________________________________ http://inbox.excite.com
Hi Wolf, The observation that noise from a loop increases in the presence of another antenna such as a vertical increases has been discussed before on the reflector, (presumably coupling of noise pic
Hi All, Do we need to stick with this bandplan? When it was devised it reflected interests at that time among a rather small group. Things have moved on since then. Most activity is in the miniscule
Hi Dick, Since most replies to your query were somewhat inaccurate, I thought I would set the record straight. See: http://physics.nist.gov/cuu/Units/checklist.html 73, John, G4CNN
Thanks to Bob, Markus and Alan for their helpful comments. On the question of multistrand wire, it occurs to me that the problem might be even worse with Litz which has not been adequately cleaned. I
