Hotspoy with stock antenna

Post by K9JPT » Sat Aug 07, 2021 11:13 pm

Dear Forum,

The rule book for Open GD77 states:

Do not use the antenna on top of the radio when in hotspot mode, this usually causes RF injection problems which can't be resolved by screening or ferrite chokes.

Ref: https://github.com/LibreDMR/OpenGD77_Us ... d#batt-cal

However, I have been using my stock antenna on top of the radio for almost a year now with no noticeable consequences. Is the information about this in the rule book up to date?

It may work for you, but most people have problems with RF injection when using the antenna on top of the radio.

Hence why the advice is not to do this.
