Dave, I should have said...
I can send you the parts LIST that you need to change in the TKR-720S VCOs (Both TX and RX) to make it a K2 if you would like. That is what I have done with both of mine here and they work GREAT!! james// -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of JamesMNelson Sent: Monday, April 24, 2006 8:02 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Re: TKB or TKR-720 on 220 Mhz band Juan, I hate to say it but on this one you are wrong. The TKR-720 was build with two different splits. The K (or K1) split ran from 150.00 MHz to 174.00 MHz and the K2 split ran from 136.00 MHz to 150.00 MHz.

Juan Tellez A, XE2SI EEWW.. I know the 720 was made in at least two band splits, because we got the wrong one at first and it wouldn't come down into the ham band. Wether you can program it there is a very different question from wether it will operate there. Inherently broadbanded designs are inherently bad for repeater use. In our case, we were finally able to eke out 18W without the solder melting on the finals, after I replaced the regular solder with silver solder, and added small heat sink fins. The 720 we had also had a synth issue. After being in service for 3 months or so, it started hopping between our frequency and the local airport tower frequency. This happened very quickly, such that it appeared to be transmitting on both bands at once. The synth was madly signalling to the CPU that it was unlocked, and the CPU was blithely ignoring that. I'd be very surprised if there was a single 720 model that covered this spread. I'd be even more surprised if using it that way was a good idea. Yahoo!
