Re: [Repeater-Builder] Tait UHF Standby Repeater D-Band
Hi Marcus, These come in all shapes and sizes, D band cavities are particularly hard to obtain at the best of times. Quite often cavities are not needed, especially if the Duplexer is a bandpass item. these are usually added on a per site basis. It's good housekeeping to have a bandpass filter system, generally as the Tait duplexers are notch devices only.

[Repeater-Builder] Re: Antenna spacing
Jeremy, I have a MFJ 2 Meter Data radio on 145.010 at 5 watts on my packet BBS. It has a Diamond F-22 20 foot to the antenna mount using rg 213 cause the run to the shack is short.I use a Diamond X510HDN with a Yaesu FT-8800R running 50 watts and the antenna is 30 Foot to antenna mount. I use the Yaesu on all repeater freqs in this area and have no problems. I have the masts about 10 foot apart.Hope this might help 73 de Mike KC8FWD
[Repeater-Builder] Re: MSR-2000 Receiver Preamp
Hi Wayne, The original MSR-2000 Receiver Preamp relative to an ARR (or Angle) GaAS gas-fet has less gain and a noticeably higher noise figure. I have used both the original and an external preamplifier on pretty much all versions of the MSR-2000 Receivers. Depending on your Duplexer, the operation of your system would normally be more improved with an external added GaAs Preamplifier versus using the original unit. Better third order performance is one benefit. I know everyone is in love with Angle Linear Preamps and they're very good products... but I also use a heck of a lot of ARR GaAs Preamps because they're a great dollar value and they work very well. Regarding the active device inside the box (the transistor or FET): Phempt device amplifiers are wonderful, GaAs (gas-fet) are great, bipolar types have their place in many applications but what's in front and behind the box (filter-wise) also matters a great deal.

I agree that simplex freq's. on each radio would work, in which a simple notch type duplexer or filter cavity would probably surfice.

Here, we have a repeater on 147.06 and digi on 144.39. We're using an old Sinclair Q2B05D duplexer to combine the two. The voice repeater has it's own duplexer. The antenna port of that duplexer feeds the high frequency port of the Sinclair duplexer. The Sinclair pass response is wide enough to pass both .66 and .06 with no problem. The digi radio feeds the low frequency port of the Sinclair. In addition, we needed to add a pass cavity to the digi radio, and a pass cavity to the repeater receiver. It all works great, with no desense to either receiver from either transmitter. Several months ago (May or June?) on this list, someone posted *their* method and diagram for doing the same thing.

Here, we have a repeater on 147.06 and digi on 144.39. We're using an old Sinclair Q2B05D duplexer to combine the two. The voice repeater has it's own duplexer. The antenna port of that duplexer feeds the high frequency port of the Sinclair duplexer. The Sinclair pass response is wide enough to pass both .66 and .06 with no problem. The digi radio feeds the low frequency port of the Sinclair. In addition, we needed to add a pass cavity to the digi radio, and a pass cavity to the repeater receiver. It all works great, with no desense to either receiver from either transmitter. Several months ago (May or June?) on this list, someone posted *their* method and diagram for doing the same thing. Perhaps that person could re-post the info. Or, search the list archives. Laryn K8TVZ
