Another option is to buy another mono Marti transmitter receiver pair. Another Marti STL 20M system is slightly cheaper than a composite system. You can also find refurbished STL-10/R-10 combos on line for around $2500. You would then need a combiner (sometimes called a "circulator") which will allo...

You need to buy a stereo (i.e.--composite stereo) transmitter and receiver pair. I would recommend an Armstrong X-Link rather than the Marti composite STL systems--have two of the later at one site, and have had periodic problems with the power supplies. If you have a good signal with the present sy...

Have fun reading all 33 pages of comments.

There is a registry hack that is supposed to cure this problem--but it doesn't. Apparently prevents Windows from taking over an operating computer. However, if the computer is turned off, or re-started, the update sequence begins again--and the registry entry is re-edited.

To answer your implied question--pick up a cheap refurb computer with Windows 10. Show your customer what happens when you turn it on (as it begins ten minutes of updates). Then ask him if he wants his station to go dead unexpectedly while Microshaft forces the updates to make sure you have the late...

Getting drawn into a choice of rebuild or downgrade and replace on a 5 kw AM. 1993 Gates 5, we were turning it off and on, off and on over several days while a cell installation was hoisted up the tower & tuning networks reset. Now makes about 2500 watts, PDM section looks like the national Christma...

Had that problem with amber alerts overriding live high school baseball broadcast. No way to access settings in the "home phones" (cell box with no screen/no keypad--just telephone jack). Hard to get a hard wired line in the middle of a high school baseball field.

Heard from the manager at a student run station at the community college. He was teaching a class--Half the students phones triggered, most of the class confused and slightly panicked.

On one of the models of this STL (sold by Armstrong, but essentially an RVR) I discovered that if the fan quits, the power supply is powered off (probably current sensing--no current draw by fan--supply shut down to prevent over-heating). So...replace the fan. On the unit I had even a small CPU fan ...

Look for Gentner SPH-3's on E-Bay. Analog hybrid, you need to fool with the null for the best rejection of send audio--but probably much better than the Heath Kit. They run in the low 3 figures--one on there now for $125. Another tip: If you can get the cash, get the ART 351 mono equalizer. Sweetwat...

Econoco is now owned by CPI (e.g.=Eimac), although the refurbs go through a different plant. I'm getting about 18 months on the 3CX3000a7's in an ECO-4 and ECO-6's I take care of.

Call Comrex...folks there are quite helpful.

Don't know that model but some of a similar age--I'm thinking the Belar series--were fixed tuned.

We experimented feeding a booster with a pair of Comrex Bric Links. First, in order to synchronize the audio, you would need to find some way to delay the main transmitter audio to match the transmission delay to the relay. We were finding a variable delay time which then adds to the complexity. Had...

Looked into folding back to 7, but this was a refurb computer.

Got an external ss drive, installed new os on it, then transferred over the files we needed. Appears to be stable--at least until the next time Microsoft finds a way to start installing updates.
