Re: [Elecraft] KPA1500

I believe Alpha warns not even to try to move the amp with its transformer installed. It is connectorized so you can remove the transformer in a few minutes and then transport it and the chassis separately. Otherwise, you risk bending the chassis under the weight of the transformer, assuming you

I’ve been experiencing an issue with my K3, and I’m wondering how to troubleshoot it. Here’s the symptom. Often, when I’m trying to work a weak DX station, I’ll switch the sub receiver off and on, so I can better hear the DX station, then to try and hunt for the station he’s working.

Re: [Elecraft] Advice needed: Remote Station Enhancement

John and all, This is a problem caused by the "way things work". The original K3 did not have pullup resistors on the band data lines (correct by engineering practices, the pullup resistors should be in the receiving device). BUT as a concession to those band decoders did not implement pullup

The UM decoders don’t put 12V on the input side. They have optoisolators on the input side that can be driven directly from the K3 without interfering with the KPA/KAT setups. I’ve got several in my setup and they work great. The outputs are active low, so if you have high side driven relays

Interesting idea, but I would talk to N6TV before going too far down this path. The reason is the introduction of +12V on the Band lines will cause issues in the KPA500 and KAT500. There is a series-connected 220 ohm protection resistor in the K3’s Band signals. When +12V is placed on the band

For a band decoder, I like the Unified Microsystems device: http://www.unifiedmicro.com/decoder.html To use this device, you would put +12 VDC on all the relay coils, and the decoder would ground the appropriate relay to pull it in. I would use cat 6 cable for the run out to the relays, with
