So I guess a TX power no greater than 4W would be sufficient to meet the 1W ERP limit? A super efficient, optimally tuned Class-E single-FET amplifier capable of the necessary power would indeed fit
Mike Local coverage over here is around 500 miles daytime. I can qso at this distance daily on both 137 and 500 and a fraction of the power that you guys run. I can work OH1TN and the Italian stns at
Typo error may be ..... ''Like I said you could put my PA (transistor) in your pocket'' Or could have a coat like Fagin's ? G :) On Mon, 15 Dec 2008 21:40:48 +0100 Rik Strobbe <[email protected]
John, The radiation resistance of this antenna must be about 5 Ohm, with a loss resistance of 20 Ohm the efficiency is 25%. So I guess a TX power no greater than 4W would be sufficient to meet the 1W
Tnx Rik Like I said you could put my PA in your pocket. My ability to RX is a big benefit I could copy RU6LA just gone dark at solid O copy. Lazy mans cw is correct but not my choice. You forget to m

1/4 wave inv L at over 100 ft high. Hello Mal, a great antenna, congrats again. I (and maybe some others) can only dream of such an antenna. The radiation resistance of this antenna must be about 5 O
Hello Mal, last night I could copy your QRSS signal (or should I say lazy man's CW) 599+. Congrats on the nice signal, your were beating SM6BZH (who was claiming 3 W ERP) by about 10dB. 73, Rik ON7YD
