Re: [Repeater-Builder] Converting a TKR-750/850 for Amateur Usage
No problem. You should find the 840 to be a very nice repeater (except for the wide front end). Ed Yoho W6YJ Adam Feuer wrote: Thanks Ed!!

What was programming them like out of band? Adam N2ACF Ed Yoho wrote: Adam Feuer wrote: Ken, How about the TKR-840? Any idea if that one will go down via the software and tune without issues as well? Adam N2ACF Adam, I and others are using the TKR-840s here in so-cal. The only down side is the helicals are not narrow as you would normally find in an older GE/Ericsson or Motorola receiver. I don't remember exactly how wide, but IIRC they are about a 15 MHz wide quasi window filter. Here in so-cal we receive low (440-445). Depending on where in the band you need to receive, the helicals may or may not make it that far. They are easily bypassed (part of the unit's design). Ed Yoho W6YJ Yahoo! Groups Links

For example, you do NOT need to spend $100+ on a programming cable. A standard, run-of-the-mill serial cable is all that is needed (along with the KPG-91D software) to program a TKR.

The only down side is the helicals are not narrow as you would normally find in an older GE/Ericsson or Motorola receiver. I don't remember exactly how wide, but IIRC they are about a 15 MHz wide quasi window filter. Here in so-cal we receive low (440-445). Depending on where in the band you need to receive, the helicals may or may not make it that far. They are easily bypassed (part of the unit's design). Ed Yoho W6YJ
