As I understand it, all Baofeng radios use an image based mechanism to set their memories, etc. They don't offer any form of rig control that let's you control their VFO live. I've been looking at Chinese radios with rig control for for some time and the only one I've found that looks like it comes close is the Btech UV-50X3 but many of it's reviews are bad (Yaesu FT-350 knockoff). If you want a radio with rig control, you need to look at something like:
Hobby Radio - big PCB; low power but triband - https://www.hobbypcb.com/products/uhf-vhf-radio/rs-uv3
SRB MX145 - VHF and small; low power - https://www.argentdata.com/catalog/product_info.php?products_id=134
I also know that Argent Data will be soon carrying an updated Friendcom radio module as well:
higher power - https://friendcom.en.alibaba.com/product/60195806576-209713635/1_5W_Power_Ra... http://www.wireless-rfmodule.com/buy-radio_data_modem.html
There are other options out there but:
- Kenwood v71/D710/Yaesu FT857 all work well but high power and expensive for a foxhunt device - https://www.sv1afn.com/dra818.html - deadend (no response from vendor on email, ebay, etc)
Maybe other list members can give you ideas (I'd love to hear about them too)
