I’m brand new to GRMS. In fact I purchased my Rocky Talkie Expedition radios simply to have some longer range communication for backpacking, hunting and around the neighborhood with my kids. Still waiting on my FCC license/call sign to come through, but in the meantime I’ve been doing a lot of research into GMRS and other radios and I’ve been listening to a bit of radio traffic out there. I was as able to listen to traffic on a couple repeaters that were WAY beyond my range (like 50 and 70 miles away) and with no line of sight. Then I discovered tropospheric ducting and my curiosity has continued to grow. I realize being indoors and in a vehicle is no bueno for signals.

Is anyone aware of any vehicle mount antennas that are compatible with the expedition? I’d love to be able to use these in the car, but it seems like the antennas that Rocky Talkie offer are not necessarily proprietary, but designed to maintain waterproofing and have a unique fitting. Just looking online it doesn’t appear many (any?) third party antennas would fit. Has anyone had any luck with a vehicle antenna or perhaps adapters that might work?

Thanks!

I recently purchased an ar-8118 and upon setup I had to do a factory reset. When hooked to the computer for download l, it isn’t showing any programming after a successful download. There isn’t any programming on the radio now. Does anyone have the gems tune from the factory. I can manual tune but that’s it.
Thanks
