Internal mic vs Filter Bandwidth permormance

Post by sy9dok »

Hello all. New to this amazing little radio.
I have recently received an assembled unit from the disqualified partner. Unfortunately i did the purchase since it was in stock and with a 2 days delivery to Greece. After that i found out the whole case.
Anyways. I also have ordered a Classic Bands from the approved UPTECH store since it fits my needs better in terms of operation and waiting for it to arrive.
Problems i found so far and need your advise.
Ok, i wont discuss about efficiency that is in the 65-76% margin and from 4.7 to 6.5w out.
My biggest issue is the mic and some strange behaviour per filter bw.
I get reports that my audio is like having RF in the shack or overdriven. Tried every possible combination of filter bw and it's somekind better when in 4K BW. In other BWs its really terrible. Tried an external mic following the long discussed external mic cases in this forum but it stays the same. The behaviour though is not steady. There are some (very few) times that other party in the qso says that the mic is ok.
Is this something common to others? Any suggestions?
