[Repeater-Builder] Re: UHF Connectors for 1/2 Andrew Superflex

Jim, Thank you VERY much for trying this and letting me know. That will save me a lot of time with this project. I have read an article that uses 1/4" superflex with PL259 and UG176 reducers, and will order some new cables and connectors for the jumpers I need. Superflex is cheaper than RG214

[Repeater-Builder] Re: Sinclair UHF Receive Antenna Multicoupler Question

Thanks Eric and Walter. I just wanted to see what to expect when I hooked this up, and so far it does only show about 3db gain, which makes sense to overcome the splitter. I was able to adjust it using the couple of tuning screws to center on the 450 band. Has a very sharp tuning slope though s

[Repeater-Builder] Sinclair UHF Receive Antenna Multicoupler Question

Good Day everyone, Does anyone have experience or tuning info for a Sinclair UHF Antenna Multicoupler? The model on the rack panel is "CR4-302CF" and contains a power supply, pre-amp (or preselector) and BNC distribution box (1 to 12 outputs). Looks like 450-470 range. I haven't hooked this u

[Repeater-Builder] Re: Service Monitor Question

Thanks for the responses so far. I didn't mean to incide a war over this, but the going rate for an IFR 1200S is around $4,000 - the reason I'm looking for a less expensive option. If anyone can speak about Cushman monitors (the 4000) I have a lead on one of those. Otherwise, I'll try my luck g

[Repeater-Builder] Links using Motorola Tone Remote Wireline method over IP

Wondering if anyone has ever linked two Motorola repeaters together using the Tone Remote Wireline methodology (2175 Guard Tone, specific function tones, etc) over IP? Normally these links are run via dedicated microwave links or T1 lines (i.e. on all the time). I'm thinking perhaps of using

[Repeater-Builder] Re: Mobile Duplexer for 30W repeater ok?

Thanks to everyone so far - it does make sense from the power limits, but if it will work at 443/448 ok or not (out of commercial bandwidth specs). What level of isolation (DB's) should I be looking for in a used duplexer then? Tony --- In Repeater-Builder@yahoogroups.com, "kt...@..." wrote:

[Repeater-Builder] Mobile Duplexer for 30W repeater ok?

Just a double-check question. I'm thinking of buying a UHF mobile duplexer to use with my repeater at home. Since I'll only be running 30 watts, any opinions if this is a bad idea? Most of the older style "cans" are getting higher auction prices, but some mobile packs are pretty reasonable. T

[Repeater-Builder] Re: GM300 repeater build ?2

These radios are out of depot service, so Motorola probably won't touch them. Usually you just get a blank 8-pin RJ-45 and short the hangup pin to ground so that PL will decode correctly (I don't remember the exact pin numbers at the moment - sorry). It could be just local mic audio being inject

[Repeater-Builder] Re: Need MSR2000 PL Reeds or alternate suggestions

Thanks everyone for their feedback. I have two reeds on order from MDM and will just go with that. Yes, I've told the customer that by 1/1/2013 we'll have to be narrowband, but this is a short-term backup solution so by then we'll figure out something. --- In Repeater-Builder@yahoogroups.com, "

[Repeater-Builder] Need MSR2000 PL Reeds or alternate suggestions

Hello Everyone, I'm in need of two 97.4Hz PL reeds for an MSR2000 using the TLN5073A duplex card (one TX and one RX). I haven't been able to located this particular tone elsewhere so maybe someone here could help. Does anyone think sticking with used reeds is still acceptable for redeployed co

Thanks Joel (and others). Yes, this might be what I'm looking for. I've passed along this information to my group here in Milwaukee, and already contacted the company and signed up on their email reflector. Tony --- In Repeater-Builder@yahoogroups.com, "Huntley, Joel" wrote: > > You might want

[Repeater-Builder] Re: Analog Repeater to APCO25 conversion?

Thanks Gentlemen! I was hoping that pure-FM could stay in the picture somehow. I'll do some more research (other than Wikipedia and Daniels' P25 training guide) to see if this can be done. I'm not too worried about the "logic" part of it, only if it could be attempted (APCO Phase I equipment has

[Repeater-Builder] Analog Repeater to APCO25 conversion?

I'm wondering if anyone has thought about or attempted to modify an analog repeater to regenerate P25 signalling (C4FM)? I know the easy way would be to buy a Quantar or similar box, or tying two mobiles back-to-back for flat-audio passthru. I want to find a way to recover the phase-modulated s

[Repeater-Builder] Re: Astron Rack Power Supplies or Motorola for new project

Thanks Bill for the reply. Just to be clear to everyone, I'm not going to swap-out the MSF5000 PS since it works great. I was thinking about the MSR if I consolidated it into to a different cabinet with other equipment. --- In Repeater-Builder@yahoogroups.com, "William Becks" wrote: > > Tony,

[Repeater-Builder] Astron Rack Power Supplies or Motorola for new project

Hi everyone, I just picked up a MSR2000 and MSF5000 recently. I'm wondering what the group thinks about using an Astron PS in place of the Moto back-breaker (sorry, mine still hurts) that came with these units? I've never seen a Moto fail, but for consolidating these two into a taller cabinet,
