I use KPG 66d for the software. I think the later version uses kpg 91 for something like that. If I just turn the repeater on and not hold the pf-1 key then I get the screen for channel entry. I would like to know if there is a firmware upgrade and how it is done. It surely can't be done through 66d as it says there is a connection error. I am thinking maybe since the frequency is so low that I may have to bring other things inline before I can get 8 volts. Tell me one thing....is there an led somewhere that tells me if it is locked on frequency or unlocked?

Firmware is kinda like BIOS. Holding dowd PF-1 while powering up puts it into FIRMWARE program mode. The number of decimals or periods showing on the display tell you what baud rate to program the firmware in at. Now, do you have a version 1 or 2 radio? What KPG software are you using? I must say I am a bit surprised you cannot get the VCO voltage to 8 volts, but 5 should be ok anyway. ----- Original Message ----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> > To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> > Sent: Tue Apr 07 19:42:31 2009 Subject: RE: [Repeater-Builder] TKR-750 It only says K-1. Goes from 146.000 to 174.000 or something near that. I am confused at what the manual calls firmware. Is that like bios in a computer or does it also take in programming the channels. Also the manual talks about holding PF1 while turning on the repeater to put it in programming mode. If I do that, then I can't get the software to work. If I just turn on the computer without holding anything, then the software will work. Then there is also reference to K,E. Is E just another model? Anyway, what do I need to do to get the test points up to 8 volts? About 5 is the highest I can get. The repeater was originally on a frequency in the high 150's.

The K and the K2 overlap coverage from 146 to 150mhz. From what I understand the RX pre-select really determines freq coverage on those models. ----- Original Message ----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> > To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> > Sent: Tue Apr 07 12:57:47 2009 Subject: Re: [Repeater-Builder] TKR-750 At 10:18 AM 4/7/2009, Randy Brumback wrote: >I need to tune the VCO for my amateur frequency in the TKR-750.
