Re: International crystal manufacturing
MCI had a similar nationwide system with UHF repeaters but I don't know if or how it was tied into the switched network. Anyone from MCI on this list? Our company's warehouse is a former MCI microwave

Re: Circularly-polarized antennas for two-way?
Good question. Simple answer: no, generally speaking, a regular SNR voter and two separate cross-polarized antennas won't be effective in combatting mobile flutter. The rate of mobile flutter is

There is absolutely nothing on repeater-builder on programming the Mastr III station. Anybody want to write something? Mike WA6ILQ

Re: R1225 Ribbon Cable set
There's a set of original cables here: https://www.ebay.com/itm/ 234742183745 ( https://www.ebay.com/itm/234742183745 ) But the price is, in my opinion, OUTRAGEOUS. All they are is 1/10 inch spaced

Re: MIII Programming Software
M III ver 17 was the last version we had also. The RPM software we got IS tied to computer by a key. The only way around we found was to clone the hard drives, which meant you had to have the same

Will a voter switch fast/often enough to keep up with the flutter style fading? Eric WB6TIX

Re: MIII Programming Software
The last version of the Mastr IIe/III program, which I believe is V17, is what is needed, and it is not tied to a PC. It looks DOS based, but it runs fine in XP at least. ProGrammer is what is tied to

Re: MIII Programming Software
That has been my experience as well, at least for analog stations. You may need the Windows software to program a P25 station which has a DSP card needed for P25; I don't have any P25 stations so

Re: MIII Programming Software
For the newer stations (stripes) you will need the newer win based software package that is tied to you computer. I don't know if Harris still supports these stations as we bought everytning we needed

Re: Circularly-polarized antennas for two-way?
Actually, My suggestion is for the second antenna to he a horizontal loop avoiding the hassle and loss related to a CP antenna.

Re: Two UHF repeaters sharing the same antenna.
I did lol we're going to try to go back up to the side again over the Thanksgiving holidays hopefully we can get this thing back up online and working. Frequency on the ham band is 444.050 plus offset

Re: International crystal manufacturing
Their modular oscillator units have great temp stability specs, so we tried to order the one that puts out a modified sine wave, but was told something like 100 would be doable, but not just a few.

Re: Circularly-polarized antennas for two-way?
Comprod looks interesting but can it be stacked in bays? Plus the cost is likely high for the average ham... I would think you could get a tubing bender and make your own for a heck of a lot less.
