CHIRP

I just received a set of RB27 radios (RB27, RB27B, RB27V and RB627) from Retevis so I will be looking into it.

I have created a test driver module for the Retevis RB27B (FRS) radio. It uses the Vendor: Retevis / Model: RB27B selections. Here is how you use it.

1. Download the bf-t8_1 rb27b - frs.py test driver module and save it to a convenient location.

Note: Be sure to left-click the link and then click the download link near the top of the page that loads. Right-clicking the link to download the test driver module will not work.

1. Load CHIRP
2. Click Help in the menu bar and enable Enable Developer Functions
3. Click File -> Load Module to locate and load the test driver module that was saved in step 1

At this point CHIRP will have a red background to indicate that it is running with an external driver module loaded. This does not permanently change your CHIRP installation in any way. Once you close CHIRP, you will have to reload the test driver module again before you can program the Retevis RB27B.

Before doing any editing, be sure to save your first successful download as a CHIRP Radio Images (@*.img@) file to be kept as a backup. Once you have your backup saved, test whatever you care to test. Let me know if you find something that doesn't work.

Hi Jim,
Thanks for working on this.
Works for download.
Changed MR channels and squelch and TO saved OK when uploading back to radio

great

Setting FM radio freq does not save it to radio.

Gook catch. This has been broken since the BF-T8 driver was created. It saves to the radio but it is an invalid value. I had the variable type incorrectly defined. Fixed and working now.

Can you show NOAA freq/chan in download on memories page.

No. But you can add them to the RB27 GMRS radio if you want.

Settings page NOAA select only has first 7 channels out of 11

Good catch. These have been missing from the list since the BF-T8 driver was created. Missing frequencies added to the list.
