I have a pair of 30S-1s, and I always thought that the ALC circuit was like shutting the gate after the horses had already run through..... gotta make grid current to prevent grid current... but neve
ORIGINAL MESSAGE: REPLY: More like shutting the gate after the first horse has gone through and preventing the rest of the herd from escaping. Having said that however, I am not a believer in the use
Zero is an absolute value which really doesnt exist in the 4CX1000A. There is enough overhead to do what Gary mentioned. Carl KM1H _______________________________________________ Amps mailing list Am
One gets away / some get stopped / one gets away / some get stopped ( repeat-repeat-repeat ). I would prefer an ALC with a variable conntrol that could be adjusted to limit the exciter *JUST BEFORE*
Amplifing the rectified RF is an easy way to increase the ALC sensitivity. The NCL-2000 used a voltage doubler that was quite effective. Ive also seen more elaborate circuits. Carl KM1H _____________
That should be do-able by using a hot carrier or amplified RF level sensor at the input of the tube/s to develop the ALC signal. -- Ron KA4INM - I'm proud to be Chuck's pop! ________________________
ORIGINAL MESSAGE: REPLY: By using only the ALC in the transceiver, this is what you accomplish. That's how I do it. 73, Bill W6WRT _______________________________________________ Amps mailing list Am
