Last week I bought up the new RT81 radio, we only use it in DM­R, loaded the codeplug according to the ins­tructions but I have 2 problems:

a) in transmission it works both on time sl­ot 1 and on time slot 2 even if the enco­ded codeplug is set for each channel on a specific time slot.

b) in reception the filter does not work correctly, unfortun­ately when the radio is tuned to a chann­el listens to dirty signals from another channel for another tuned to another sl­ot and Contact (talk group).

if you have no other indications to prov­ide and resolve the anomalies. I will ha­ve to return the rad­io to the shop.

We chose this radio for a blind hamradio friend.

Thanks for your kind reply
