RE: [Repeater-Builder] Re: Motorola Board identity
Wes, I can help with some of the numbers. The TRE1201 is listed in MOL as RCVR 4 FREQ 25KH and is cancelled. The TLN4294 is a MICOR PL Tone Decoder board. The 19D402308G8 is listed in my GE microfiche file as HB UHF MASTR PRO EXCITER and is described as intended for 470-512 MHz, 30 and 60 watt transmitters 4ET59H30 and 4ET60H30-41. It is 1 frequency, with Channel Guard. LBI-4432 covers this exciter. I am not familiar with GE Mastr Pro equipment, but I suspect that this exciter actually generates a VHF carrier which is then run through a tripler stage to get a UHF drive signal to the PA. That would account for your 158.925 MHz crystal, which would result in a TX of 476.775 MHz. However, Part 90 of the FCC Rules does list 158.925 MHz as a valid Public Safety frequency. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Wes Bunker Sent: Wednesday, May 09, 2007 9:32 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Re: Motorola Board identity I do not have pix, but here are some board numbers: TLN6733appears to be an audio board TRE1201appears to be a receiver HLF 4068Bappears to be a 800 mhz txcvr TLN 4294tone board ??

I noticed the documentation states the LED's now flash for 60 seconds before going solid, and using the same modifications posted may present a problem to some controllers- it would pulse the logic input for the first 60 seconds, might be an issue. I also noticed it has an external antenna port already and a ?V 200mA output for alerts to trigger their strobes or other external devices.

RE: [Repeater-Builder] Re: Motorola Board identity
Joe, I don't understand your comment. I stated that Part 90 does list the specific frequency only to note that the part number of the exciter board is described as for the UHF band 470-512 MHz. If the exciter were intended to operate with a tripler on 476.775 MHz, the crystal would then be marked 158.925 MHz which, as we both noted, is a Public Safety channel. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of mch Sent: Thursday, May 10, 2007 10:25 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: Motorola Board identity Huh?

Re: [Repeater-Builder] Quasi-Simulcast?
Seems like Tait Radio used that name - not familiar with the techniques involved. Steve
Re: [Repeater-Builder] Quasi-Simulcast?
I would assume that it is similar to 'Free Run Boost'. The transmitters would be really close to the same frequency but not syncrhonized and it would rely on the FM capture effect. Unless there is 15dB of difference in received signal strength you get ot hear the 'fight' which sounds intresting to say the least.

However, none of the articles addressed my logic board directly. I have the 5pin board and I think I want to make this a sdown and dirty as possible.. I will just cut one end off of a db-9 serial extension cable and run it out the back hole of the radio. I need the usual stuff-- ptt/cor/audioin-out and I really want to find a place for PL detect as well..
