Com and antenna question - new info

New information: I can transmit and be heard on 134.65, but can't receive. Does this help pinpoint the problem?
I have a Microair M760 com and a $40.00 bent whip antenna.
I can talk 10-15 miles or more on the "lower" frequencies (122.9 for example)
Highest frequency I can get is a ATIS at 133.675.
Can't get a local control tower at 134.65 or another ASOS at 135.775.
What are the chances a good Delta Pop or Comant bent whip would solve the problem?
Thanks,

Sounds like it could be more of a radio problem. The antenna shouldn't be that sensitive on receive.
 
Slim to none. The difference between those frequencies is inconsequential to the antenna. However, your transceiver may be swapping to a different circuit as you change frequencies. Try easy stuff first: get into any rotary switches attached to the frequency knob and spray with contact cleaner.

Radio range should be more like 50 miles or more, the only real way to determine is to have the radio tested for proper power and sensitivity and go from there.
