My GM30 has been that way since I "tried" to update the firmware. When you tap the * button, my GM30 goes from L to H on power. But when I change frequencies, I have to do that all over again. It is easier than going through the menu each time, but still a pain. Hope it helps a little.

I have a tram 1480 with ground plane up on a 28 ft pole and was having reasonable success on the 2m and 70 cm bands on ham, and my gmrs jpole antenna connector at the antenna broke in a high wind event. I swapped the coax connector at my DB-25G radio to just listen to a little gmrs action. Sounded pretty good. I thought just for giggles that I would hook up my nano vna and check out the signal on the gmrs bands that cover repeaters. 467.550- 467.725. I was shocked that my swr was never worse than 1.75. Now keep in mind that as I checked 462.550 up to about 463.000 that the swr got a little iffy, close to 3.0. I live in a very low area, so transmitting at only 28 ft up didn't gain me any access to any repeaters. But I sure could receive. When I can get my antenna somewhat higher, I may be in business. I bought this 1480 online through Home Depot, and since then they have gone up in price. But that was where I found it at the lowest price. Maybe this was a quirk, but this was my experience with that Tram 1480. Will here at WRNV384.
