Mal, If you would spend half of the time you take each day writing nerving mails, you could at least transmit your full callsign each day in DFCW-600! Roger/G3XBM has once written a comment that hits

LF, I can read "BHZ" in QRSS-3 (given in QRSS-10 but 10 Hz to low for my QRSS-10 window). Is it SM6BHZ? I remember this call of last year :-) *happy* 73, Stefan
Roger, I can make a grabber window, just for you, if you want. At the desired QRSS mode and at a desired frequency... 73, Stefan Am 30.09.2010 19:50, schrieb Roger Lapthorn: Mal/Michel, Thanks for th
Hello Roger, Maybe you can send us a circuit with its values. I have built class E PA for 2200/160/80/40/30/17/10m and have some experience. If you are using a IRF510 and stay in the QRP range (< 10
Wow, can i take a part of this interest? ;-) Stefan/DK7FC Am 29.09.2010 07:50, schrieb Mike McAlevey: Congratulations to Scott and Kuni. We look forward to seeing your signals in ZL. Mike ZL4OL
Hi Alberto, Indeed. Most (USB) soundcards for < 5 EUR can easily handle 48ks/s. Additionally it would be fine to receive even above 11050 Hz since e.g. the ALPHA transmitters starts to TX at 11904 Hz

Hello Jim, Of course i could give you some numbers of calculations. Your described station should not radiate too much power ;-) But maybe Jim/M0BMU is the one who can not only do it better but also
Dear LF, I am back in Germany, after a very fine und friendly weekend in France. First i want to thank all those for the support, the activity and the reports here in the reflector. Special thanks to
Mal, LF, It is a wire, 4 m above ground. It is grounded at the far end, using 20 * 0,4 m loong copper rods, about 1m spaced. The same ground electrode array is near the other end of the antenna. The
Tnx Roger, Yes, my earth antenna is near field. Thus i am optimistic to see my signal there which might give first impressions about the performance of the antenna and so. Since i am > 30 dB above no

Mal, I can read my letters but very weak. You have the dots up and the dashes down. No idea how this antenna radiates in your direction. Maybe it is rather S/N oriented. This can be proved by more rp

Hi Daniele, I would assume it is independent of the distance. It is rather defined by the type of noise, which means the Spherics here. But i am not an expert on this. You can apply a test signal in
