1 thing I can say for the TM-V7100A is, unless it's unconventional, it 
probably has an SO-239 connector for the antenna, and those are completely 
worthless on 900 MHz, unless the antenna is right next to the transmitters 
for the headset, the loss between that and depending on your coax, could 
honestly be so much that you're just not hearing it. We have a 900 MHz ham 
repeater locally where the person used PL-259 connectors and RG-213 and it's 
range, at 30 watts was about 1/8 of a mile on it's best day with about 3 
watts making it to the N connector at the antenna, make that a PL-259 too 
and it would probably have acted like there was no receiver at all. That's 
just a thought, beyond the antenna not being made for that band likely, you 
may have a lot working against you. Other than that, I don't know what the 
problem could be, I can hear baby monitors and headsets like that on my 900 
MHz radios no problem but really, any broadbanded ham radio, my TM-G707A I 
used to have, the hand helds I've had, none of them worked up there though 
they covered the frequencies. They just are deaf.
