Not sure about LPH or LMH. I think I had EPH's?

Got an email from one of my fellow volunteer firefighters who was also on that call. He and another two people went in there today in the daylight to see what the deal with communications was that night. He said, "Also we figured out why radio communication was not the best--there were ridges on all sides that blocked transmissions and noises. That is some of the most convoluted country I have seen around here. These were the worst conditions I have seen in 12 years.  I hope it is that long before we see conditions that bad again. "

Thanx!

It just may be possible.

With a few simple mods, a pair of LMH 5141's will make a front panel programmable frequency agile self tuning mobile or stationary repeater.

My VHF repeater used a single radio and a Hallmark Christmas card...recorded audio...then re-transmitted by Voice Operated Relay (VOX feature on radio)  Build 23 years ago and still in use daily.

Dedicated simplex repeaters like this are relatively inexpensive.  The modern generation ones even store the messages for on demand retrieval.   some even have mail boxes accessed by DTMF codes.  Simplex repeater like these are well under $100.

But it is a SIMPLE/BUDGET answer to a tough question...a couple or single unit,places in a high location ,will cast 'radio light' in the shadows...We used this method to aide Search and Recovery efforts when the SHUTTLE CRASHED and also during Katrina Confusion.
