Hi Folks, I purchased a second hand K1 a few weeks ago and am in the process of installing a new KFL1-4 that I just finished building.
The K1 is serial number 00863. The RF board is Rev. D and and the unit is equipped with MCU 109E, which I think is the latest firmware version. The hiccups: 1. I didn't have the Errata sheet in front of me and managed to install all of the trimmer capacitors on the KFL1-4 board backwards. The trimmers have two flat sides, not one (which was confusing...without the Errata in front of me). I read that the adjusting screw is to be on the side that connects to ground. Thinking I was a smart guy, I used an ohmmeter to determine which trimmer terminal that was...and I still managed to get it wrong! Anyway, I used a non-metallic screwdriver to do the alignment and all went well. That said, is there any reason why I should remove and re-install (or just replace) the trimmers now? 2. All went well when I did the 4-Band Transmitter Alignment on page 19 of the KFL1-4 manual except that output on 15m is approximately 200 to 300 mW on the K1's internal and an external wattmeter. Output on all other bands was 2+ watts. Output on 15m remains at 200 to 300 mW even when I increase the power to 5W. All other bands are OK. Low output is covered in the Troubleshooting section, but not that I can see when it's only 1 band out of 4. Any thoughts? 3. I didn't get the original manual with the K1 and there are several differences between the Rev. D RF board and the manual I downloaded from the Elecraft website. The Rev. D RF board doesn't have a place for S2 (for transmitter offset adjustment). However, there appears to be a location for a switch at the front of the board, on the bottom and immediately behind the P1 header. Same thing? Just in a different location? Many thanks for any assistance! 73, Ken Alexander VE3HLS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
