-----Original Message----- From: [EMAIL PROTECTED] On Behalf Of G3VVT The reported birdie at 28.276MHz is there, but extremely faint at about 28.275.6MHz on USB and shifts up to about 28.277.7MHz on LSB. I would think it fair to comment that most ham receivers have birdies somewhere if you want to try hard enough finding them. With what I have found on my particular QRP K2 .... ----------------------------- Bob,
~28276 is probably not the same birdie as the image of the KPA100 oscillator at 18432 at 28264. The closest one I can find depends on having the KIO2 with a 16289 oscillator on board. The oscillator's 4. harmonic is at 65156 kHz. It can be mixed with the 3. harmonic of the VFO, when the input dial is at IF + VFO = 4915 + (65156+4915)/3 = 28272 which is almost 28276. But if you don't have the KIO2 then ... 73 Sverre LA3ZA http://www.qsl.net/la3za/ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
