Bug #10454
closedRetevis H777S Unable to Modify Frequency Values
100%
Description
I am trying to program my Retevis H777S model radio to match the same settings that our H777 model is programmed to. The problem is, after turning my radio on, connecting it using the dual jack - USB cable, and downloading the settings to CHIRP, the Frequency field is greyed out and immutable. The image file that we are using and has been working great for our regular H777 models is able to have the frequency field be modified and set to whatever we choose. Other fields in the image file are able to be modified with the H777S except the frequency and a couple of others.
I tried downloading the H777 Image file to my H777S, but it seems CHIRP detects that the devices are different and doesn't detect a response from the radio when trying to upload the image.
I attached three screenshots: one of the uploading of the H777S radio, one image of the immutable frequency field for the H777S, and another of the modifiable frequency field for the regular H777 model
Anyone have any ideas? I need the frequency values and to be the same amongst models so that they can intercommunicate.
Thanks!

The Retevis H777 is sold as a full band UHF radio so CHIRP is programmed to support the full UHF band.
The Retevis H777S is sold as an FRS radio. CHIRP is programmed to match the factory software which only support the FRS frequencies.
Are you able to program the frequencies that you want with the H777S' factory software?

Hi Jim,
Thanks for the response! I tried the native Retevis software and found that like CHIRP, it must be expecting only FRS compatible frequencies so they are immutable there as well.
I guess we will have to return these H777S radios and purchase H777 in order to program the frequencies to what are already deployed at our company.
Thanks!

I have the same problem with Retevis rb75 which is sold as a gmrs radio but will not let me change frequencies
I get one of two things - either an error box (see attachment) or after overwriting it just reverts back to the originally assigned frequency
Im trying to make all channels on the radio the sane frequency to dummy proof

Give this test driver module a try. Here is how: LoadingTestModules
