But.....................it is possible that one of the radios can hear weak signals better. Most of the radios that have an S-Meter calibrated in dBm are millitary radios that are built to a certain spec. True, there may be some differences in perceived signal quality, but generally, you can take a Rockwell HF-2050, HF-8000 series, a Harris RF-590, Racal 6790, a WJ 8718, and they will all sound very similar. The design spec is going to call for a certain amount of gain, overload rejection etc. If the receiver doesn't meet these specs, the manufacturer can lose the contract. Pete |
