An Interesting Dual Band Feature
I just figured out an interesting way to use the dual band feature on this radio. When you have the dual receive enabled, the radio wants to switch the active VFO to the last one it received a transmission on. While this is fine for regular dual band use, it is limiting if you want to use the radio as the HT in a crossband repeat or remote base scenario.
Consider this scenario:
You have a base set up to transmit on one 2m frequency and listen for HT's on 440 frequency. The base is configured to not transmit anything heard on the 2m frequency back to the 440 side. On your dual band HT, you want to listen on the 2m frequency and transmit on the 440 frequency so that the crossband repeater will transmit on 2m with a bigger antenna and more power.
Using the default setting on the UV-5r, the radio will want to switch to the 2m VFO every time it hears something. Unfortunately, because you want to TX on 440, you constantly have to hit the A/B button on the radio (what a pain). Well, there is a solution to this problem!
In my example, I'm setting the 2m frequency on VFO A and 440 on VFO B on the HT. I want to TX on 440 and listen on 2m. After you activate the dual band RX on the HT (menu 7, TDR to ON), go to menu 34, TX-AB and set it to B. Now, the radio will hear everything on 2m and every time I hit the PTT, it will TX on 440! Of course, modify the settings to suit your preferences.
Originally I thought the radio would not support this functionality, but I was wrong. It works great.
