Hello friends, I've been using my tiny KX3 with a KPA500 and KAT500 for many months now. The KX3 only puts out 12 watts, but the KPA500 translates it successfully into about 200W. The KPA500 and KAT500 have been connected via the official DB15 cable sold by Elecraft, and the KX3 triggers the amp via RCA cable into the amp's PA-key connector.
Fast-forward to today: I just received a K3, and I'm really excited to see the K3, KPA500, and KAT500 all just "work together" magically. Except they're not. I've connected everything exactly as shown in the KAT500 manual: - K3's ACC port is connected to the tuner's XCVR port, via the official KPAK3AUX cable. - The tuner's AMP port is connected to the amp's AUX port, via the official E850463 cable. I'm definitely able to use the K3 and tuner together when the amp is off. But when I turn on the amp, there appears to be no communication between amp and K3. - The amp doesn't notice when I change bands on the K3. - The amp won't let me change bands at all, even when I push its band buttons! - When I put the amp into OPER and transmit 15 or 20W from the K3, the amp doesn't appear to "key" and amplify. It just shows the exact 20W as passing through (on it's 'power' display.) I've verified that the amp's RADIO option is set to 'K3'. Does anyone have any ideas? 73 de Ben NN9S ______________________________________________________________ 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 Message delivered to [email protected]
