Hi, Jurgen: Regarding 10 meters, the specifications say the K2 will deliver at least 10 watts from 28.0 to 28.8 MHz - a range of 800 kHz. It is not designed to cover the whole 10 meter band. I'm not sure where you see the power drop off, but if it's making 10 watts at 28.8 MHz it's working within spec.

Yesterday I went over to a friend and we did some quick tests on my new K2 (basic, no options yet). To be clear, everything has been aligned with basic tools, as in the user manual. Here are some things we noticed: 1. when looking at the transmitted signal using a spectrum analyser, the signal didn't seem as clean as we liked it. We didn't have time (it was the day before X-mas!) to really start counting the dB's, but on 30, 12 and 10 m we saw some signals around the main signal. Is there any chance we can get these bands 'cleaner' by further tweaking the filters? 2. Output power on 10m is OK low in the band, but when going higher up it decreases to a mere 1,5 W. Moreover the higher we go in the band the worse the transmitted spectrum gets (see above). Is it possible to set the filters so the complete 10m band can be used at a reasonable power? I know, for CW the low part of the band is the place to be, but I'd like to also install the SSB option. 3. When listening to a continuous signal (XG2 for example) there is some kind of a (digital) 'thump' in the audio everytime I turn RIT or VFO. Is this a normal behaviour or not? -- 73 Jurgen Geldhof ON5MF [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> ------------------------------------------------------------------------ my site: www.on5mf.be <http://www.ktk.be> our club: www.ktk.be <http://www.ktk.be> the Belgian Amateur Radio Society: www.uba.be <http://www.uba.be> ------------------------------------------------------------------------ _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
