The other day several of my friends were using our radios. 2 of us had NX5000s and one was using a Yaesu (We were using the Ham bands).
We were running in analog obviously so we could talk to the Yaesu.
The 2 NX5000s could hear each other just fine, but with the Yaesu both NX5000s sounded under-modulated. It was quite difficult to hear us on it. I tried it at home with another analog ham radio and had the same issue.
To make this more complicated it seems like the problem only occurs when we are using a Push to talk with Peltor Comtac headsets. We each have a different amplified PTT since the impedance on Comtacs are different than non-military headsets. Again the NX5000s can hear each other while using the Peltors, but not the Yaesu or other ham radios (at least not clearly)
Any ideas why only NX5000s could hear each other clearly on analog, but other radios can't? Both NX5000s are using the same codeplug.
*I suspect that the PTTs are not correctly tuned for the impedance mismatch and that the NX5000s have some circuit that is amplifying the weak received signal. I tried turning on and off the RX and TX AGC, but that did not seem to make a difference.
