W7OTV will have at least two and possibly more K3s on the air. WS7L and several others will be working CW, while I (AD7OG) will be running digital (at least PSK31 and RTTY) on mine. At present the SSB stations plan to use lesser rigs :-) Steve AD7OG K3/100 SN 1544

[Elecraft] K3 question--TCXO or another filter?

Greetings all, I'm getting pretty close to the time I'm expecting to see a Katiegram, and I'm thinking about adding either the TCXO or the 6KHz filter to my order. I do a lot of PSK-31 and I'm wondering if most folks find the stock oscillator sufficiently stable for digital or if the TCXO is
