I replaced a decent 8 cavity mobile import duplexer with this TXRX unit. The difference was night and day. I cannot believe the difference it made. The range was extended considerably and the sound quality improved as well. Worth the money.
Cavity set arrived and was analyzed. The high freq notch was off soecified frequency. Downloaded the Txrx 4-cavity tuning doc. Tweaked the suspect cavity. Checked against specs and found it to be "right where it's specified".
Well worth the price.
The duplexer is still working great. The previous one was in service 30 plus years. The system was struck by lightning several times over the years and finally went south and replaced by this one.
