This is certainly theoretically possible, but only if 'ground-wave' is being used. If you are using sky-wave - as all intercontinental QSOs have so far - you are limited by the length of time that t
10 K/watts is a nice starting power to start a fire with a small broomstick antenna, be daring and go for 20 K/watts for more spectacular results like the Northern Lights G3KEV -- Original Message --
Stefan, yes, I meant the BW of each Argo pixel. Unless there is QRM strong enough to cause overload, or intermodulation in badly designed audio circuits, there is no need to use a narrow filter in th
Rik, LF, Tnx for your detailed explanations! I will not forget it any more! :-) CU tmw or Sunday! Stefan / DK7FC PS: I just bought my new and biggest kite ever: 8,1m^2, that needs a 500kg braid and j
Well, if I apply 1kW to a bad antenna and get 100mW ERP, then 10kW will get 1W ERP and this is thus not nonsens of the legal limit regs but rather a gain of 10 dB. The same when you increase from 100
Dear LF, I have done some further thoughts/questions about the "gain" between the qrss modes. If the "gain" or better said SNR between qrss30 and qrss3 is 10dB, so can I do a QSO to VK with 1W TX Pow
Thanks Johan for the qualified answer! With the receiver bandwidth, do you mean the bandwidth of e.g. the argo programm or of the real receiver, say the ic706? I use a K2 with a bandwidth of 50Hz (no
Hi Johan some off air tests done between Dave G3YXM and myself seemed to confirm those theoretical figures quite nicely. Posibly still on Dave's web site. I believe others have found the same too. Ly
700Watts (or more) direct from Eu mains voltage http://www.g4jnt.com/137tx.pdf With a bit less safety margin, 1kW is quite feasible Andy www.g4jnt.com This email has been scanned for damaging side-ef
Hello Stefan, If the "gain" or better said SNR between qrss30 and qrss3 is 10dB, so can I do a QSO to VK with 1W TX Power and an antenna efficiency of 1/1000 if I choose QRSS10000000000? That?s a lit
