Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
True, but I have had success at running them at 22 watts.? have a couple of them here that I use for backup replacement repeaters while doing repairs. The last time I used it was on a VHF ham

The r1225 is still not a 100% duty cycle machine. They have a week spot at full power? the solder melts on the final and causes a failure we have on in service but cut back to 20 watts. Not always

Not always true.? For example, the Motorola R1225 repeater appears to be a mobile, but the heat sink is much larger than on the regular M1225 mobile. Joe

Re: TPRD-1554 Troubleshooting
Yep bad cap. I have had that happen a couple times. Also the BPBR coupling loops for the VHF telewave cavities for 2M are a tad longer than those use in the commercial region. There was a write up

Re: TPRD-1554 Troubleshooting
If it's the cavity on the antenna side, more than likely it took a lightening hit. Replace the capacitor and you should be fine. Just make sure you get the highest voltage one you can find. I would

Typically one gets a receiver with a tuned preselector front end, a decent IF response curve, and god squelch circuit action, as well as a transmitter that has much lower phase noise with a factory

Most mobile radios are seriously deficient in many aspects when put into repeater service. Purposeful repeater stations are generally designed to higher standards. Duty cycle of mobile transmitter 25%

I would add that building a repeater for home made from a pair of mobiles is typically done with a "flat pack" duplexer (thinking UHF here) which are cheap and band reject only. These do not perform

To retort: Many, if not most, current "factory" repeaters today are nothing more than 2 mobiles in a box. So if the act of buying them pre-packaged in a metal wrapper makes it professional so be it.

Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
Earlier in the game, the same basic guts were common to mobiles and base stations / repeaters. Obviously, the packaging of these differed. Mobiles were compacted for said environment with less

Professionalism. If you are building a repeater to put at your house, or what I would call a non-commercial site, 2 transceivers can be an option.? If you are planning on putting the repeater at a

It seems many individuals and groups when they want to put up a repeater opt to just buy a sometimes expensive box like a quantar, msf5000, msr2000, ge, kenwood, virtex, icom, etc and call it a day.

I'm working on this VHF duplexer our club acquired from another Ham. He doesn't know any of the history before he received it, so I don't know if this was factory ordered for the 2 meter band or if it
