Hi, I got on this list a few weeks ago and asked about K2s. I have a used one coming with a lot of options, but 100 watts NOT being one of them. It is CW only, which is fine, as I am about 95% CW these days. It is an older one. The SN is in the 22xx region, but has all the updates. I downloaded the manual: K2manRevC.pdf. Are there any other docs I should download? One of the first options would be the KPA100. But I wonder if there are other amplifier options I could use at home. Even 30 or 40 watts would make a big difference. I kind of want to keep the rig lower power for portable work. Full QSK is definitely important. I'll probably end up using the KPA100 anyway, especially if it separates easily. What is the typical build time for the KPA100? It already has the KAT1 internal antenna tuner. I don't know how that affects the KPA100 upgrade. Obviously, it has to be before the amplifier. I have heard the KDSP2 option is not needed. Of course opinions vary. My main concern is having enough audio to drive headphones. I have the Heil Quiet Phones and some cheap Koss UR/29s. I use the Heil with my Pro 2 and the Koss with my FlexRadio SDR-1000. The choice appears to be an impedance matching issue. The Koss's won't put out enough audio from the Pro 2. I have a moderate hearing loss, but don't use my hearing aids with headphones due to feed back. I posed this question a few weeks ago, but don't remember the responses. 73, Steve N6VL _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
