[Repeater-Builder] Need Micor 68P81014E15 manual
Anybody have a spare manual (or copy/PDF) of the 68P81014E15 supplement for the extender on the Micor T53RTA1404BA Mobile? I already have a basic 68P81014E40 manual OTW from eBay. Thanks.

Scott, If you care to pass it to me at your Dayton table, I'll scan it when I get back to GA and then mail it back to you. Let me know.

It's a Motorola photocopy. It is for the VHF extender receiver and associated parts. I don't have it scanned into PDF though. I won't have time to scan it to PDF before Dayton either. If there is a volunteer, I would be willing to lend it out to be scanned and then make it available for the group.

[Repeater-Builder] Re: Standard RP70U help? Thanks!
Mike, Brent, Jack...Great feedback. The RP70U is currently on 456.825 in/451.8625 out. The modified repeater will be 445.800 in/440.800 out (if I'm lucky). The advance warnings/tips you guys provided on the duplexer, mic connectors, manual, and volume/squelch controls will surely head off a lot of trouble. An original Owner's Operating and Maintenance Manual came with the RP70U, But I have not yet compared it with what's at www.repeater- builder.com. BTW, my scanner only goes to 8.5 x 14, so if anybody with a bigger scanner cares to add anything to the Files section from my manual that's not there already let me know at vesterscott @ bellsouth.net and I'll loan it to you. Jack, is a flatpack duplexer like the small black Celwave mobile duplexers that pop up on eBay all the time? Don't believe I've heard that term before. Brent, do each of the CTN34 tone boards perform both encode and decode. IOW, if I want the same tone in and out, will a single board give me full CTCSS for any given tone? I was not able to reach a firm conclusion on that from the manual and schematics. 73, Vester N8EKA --- In Repeater-Builder@yahoogroups.com, vesterscott [EMAIL PROTECTED] wrote: I picked up a Standard RP70U 12W UHF/FM repeater/base station today at a local hamfest--complete with AP70 phone patch, one TN34 tone board, and the operating/maintenance manual.

If anybody here has done this already I'd appreciate any additional suggestions/comments/guidance you can provide. I can also use one more TN34 tone board if somebody has a spare lying around.

[Repeater-Builder] Re: New-be and question(s)
Russ, Thanks for the plug, but it's undeserved. Ralph N4NEQ and Lin N4YCI developed the sum and substance of the current SERA 900 bandplan. Period. The pre-existing SERA 900 bandplan was basically useless. Ralph and Lin did 100%of the research and compilation, basing it (perhaps) on a similar bandplan that had proven successful in CA. All I ever did was present a couple of simple (but obvious) coordination recommendations for the purpose of making more efficient use of the existing SERA 900 bandplan. Fortunately, this didn't require many brain-cells. As far as I know, SERA has never publicly acknowledged that Ralph and Lin developed this valuable contribution to amateur radio. 73, Vester N8EKA --- In Repeater-Builder@yahoogroups.com, russ [EMAIL PROTECTED] wrote: In the front of the ARRL repeater book.

In my area, Monroe County, West Virginia, I want to put up a 1200 Mcsa repeater with the purpose of using it as a hub to other repeaters on the VHF and UHF bands. The general idea is to have the 1200 rep to do all the iding and ops while the linked repeaters be as half-duplexes with no bells n whistles themselves. However, I have yet to find any 1200 Mcs equipment. Sugestions please. Ed - [EMAIL PROTECTED] Yahoo! Groups Links Yahoo! Groups Links Yahoo!

[Repeater-Builder] Re: 900 mhz pa equip
I believe these are Class C, so they will work fine as FM or CW PAs-- probably at 100% duty cycle. They'd probably go like hotcakes for weak signal SSB if someone figures out a way to modify/use them in linear (Class A, AB1, AB2, B) service. It would obviously involve adding some bias circuitry, etc. I have a Motorola Purc 300W and a Glenayre 150W (both 900 MHz) that I'd love to be able to use that way. Way too much power for typical repeater PA use. Too big for paperweights or doorstops, wrong form factor for a boat anchor (and I don't own an ocean liner, anyway). If anybody knows how to mod these things for linear service, please share it. Thanks. 73, Vester N8EKA --- In Repeater-Builder@yahoogroups.com, Larry Williams [EMAIL PROTECTED] wrote: Anyone know the value, if any, for 900 mhz pa units that came out of cellular sites. We have about a hundred or so and they have to go. No room. I think I saw a thread for them some time back but didn't pay attention to it. Are they of use? Yahoo!

[Repeater-Builder] Re: EF JOHNSON 242-9881-2 900 MHz Radio .
I have a 242-9896-403 (900 MHz?). Any info/help/comments would be appreciated. Maybe by the time I get my stack of 86xx 900 MHz candidates on the air someone will have made a breakthrough with the 9896-403. Of course, the latest news on the manned space shuttle's return trip from Mars to the Moon will be a constant distraction then. 73, Vester N8EKA --- In Repeater-Builder@yahoogroups.com, Gene Colson [EMAIL PROTECTED] wrote: To my knowledge, No one has hacked the program yet for any of the later model Johnsons.

[Repeater-Builder] Automatic fan cooling techniques
I'm on the Dallas Semiconductor MAXIM Engineering Journal subscriber list, and today received Volume Forty-Nine, which includes a three page article entitled Automatic fan control techniques: Trends in cooling high-speed chips. I cool the 30W Maxtrac PA's in my 900 repeaters by running them at 15-18W and turning a fan on/off with PTT from the controller. The MAXIM approach has some neat ideas for more sophisticated people, however. There's also an article in the same issued on Base station FR power amplifier biasing tha tmight interest some people. Check it out at www.maxim-ic.com. No, I have no connection with these folks other than being on their mailing list. 73, Vester N8EKA Your use of Yahoo!
