[MRCA] Torn Fu.d2 restoration

[Ray Fantini]

LMRS Land Mobile Radio Services is Business band radio, some frequencies are set aside strictly for government and public safety and others for commercial use. Low band VHF (30 to 50 MHz) is the first and oldest segment and most commercial stuff migrated from there to VHF high band and later UHF where repeaters were somewhat common and allowed superior coverage. The only things that stayed down there were services that were on those low band frequencies forever like fire departments. In Maryland the state police used Low Band for decades being it was an easy way to provide coverage beyond what many VHF radios were capable of or at least that's what people thought but all that's gone now with everything being up in the new public service bands. The state just auctioned off big lots of the old Motorola 500 watt base stations, the old car radios had been gone for some time now.
I cant recall seeing a NGO ever on low band going back as far as I can remember but imagine it happened, the only NGO I can think of that was down there was Red Cross had an allocation for 47.75 or something like that. There was a non licensed allocation at 49 MHz that was used for things like cordless phones and baby monitors but most of that stuff migrated up to 800 MHz
It borders on sacrilege but wonder if you can rework the output tank and receiver front end to get it to work on the forth harmonic? 36.125 would put you right on 144.250

Here is the FCC frequency allocation table.
https://transition.fcc.gov/oet/spectrum/table/fcctable.pdf

scroll doen to page 18 and 19 , right hand column for USA.
They have it the 33 to 38 MHZ area as "private mobile" fixed mobile" and "public mobile" whatever those are.
You will have to look up the definitions on the FCC site.
For some reason, I though that spectrum was called the "business band"  for contractors, private repeaters and such, but I don't know that for sure, more research is needed.

Since I’m comfortable, but not independently wealthy, the restoration will be going slow. German WW2 radio parts make the prices charged for allied radios seem dirt cheap by comparison. And before I try to operate the radio, I have to find out more about the frequency range it operates on so I don’t get into trouble when the radio works when powered up.
