RC, Maybe. If you get a very old amp you may have difficulties with the keying circuit. More knowledgable people then I am will need to help you with that. You'll only know that when you investigate the specific amp. Not all older amps are an issue; I have a 30 year old Alpha 77SX and run directly from the K3 key out to the Alpha's "Relay in" and it works great. (I'd asked here regarding any specific interface problems before buying this specific amp)
If you use CW and like QSK, you'll want that to be a factor in your amp and get an amp with QSK. If not, it won't much matter except a QSK relaying system will always be quieter than the non-QSK versions. You might not like a loud click when you transmit or it may not bother you in the least, that's your call. 73, Gary KA1J > I wish to purchase an Amp either new (or new to me ) to use with my K3/100. > Are there any that I should avoid and will I need interfacing circuitry > Thanks RC kc5wa > > -- > "ETERNAL VIGILANCE" is the price of FREEDOM.....Thomas Jefferson > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[email protected] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
