[Elecraft] For Sale: KPA100/KAT100 Combo in EC2 enclosure

I've decided to revert my K2 back to a QRP radio to free up some funds for another radio. For sale: my Elecraft KPA100/KAT100 combo. It's built in an EC2 enclosure. If you have a QRP K2, all you need to install in your K2 is the KIO2 module. The KIO2 will talk to the amp/tuner combo via the

[Elecraft] K2 - 40m transmit problems

I'm getting HiCurr messages when I transmit on 40m, the bargraph shows multiple bars lit, and I can hear a very faint squealing sound coming from the K2 when I transmit. I've built the RF probe and I'm going through the signal tracing steps in the manual. On the PLL Reference Oscillator

[Elecraft] KDSP2 Recordings

I am considering purchasing the KDSP2 and was wondering if someone who has this option installed could post some recordings made while using it. I've listened to the two recordings on the KDSP2 page and would like to hear a few more, with different settings, etc ... I am particularly

I made a few recordings of some noise that I hear on 40m tonight. The .wav files can be downloaded at the address below. I have no idea what's causing this noise, or how to filter it out. Is this the type of noise that the KDSP2 or KNB2 could remove? Thanks, Zac KD5IEF

[Elecraft] K2 Headphone Jack and Internal Speaker

A few days ago, I plugged in some headphones to my K2 and noticed that the internal speaker didn't immediately cut out. I wiggled the headphone plug around a bit inside the jack, and after a second or so, the internal speaker turned off. Yesterday, when I plugged my headphones in, the same
