[App_rpt-users] Alinco DR-135

I have had several DR-135Mkiii and 235s and 435s all with the same audio
problem on TX and RX.  It seems that when the radio gets hot too many time
is starts happening. Worse on higher power.

I would note that the DR135 has now been replaced by DR135Mk3 which has some
substantial changes to the modulation circuit.

 

But I am curious if the radio makes the noises when you transmit with no
audio?

 

If you overdrive the URI you will get some nasty noises. One way to do this
is putting the PL and voice on the same output channel. In that case the two
gain controls (txtone & txvoice) must add up to something less than 1000, as
noted in the knowledge base.

 

Regards

 

Ken

Hello all.

 

I know I have seen a few threads on using the DR-135 as a node radio so I
decided to ask this question.

Has anyone using this radio had problems with a crackling noise or popping
noise when the radio transmits?

It doesn't matter if you are using the data port (for audio) or the mike and
speaker jacks.

Its not all the time but happens more than it doesn't.

 

Thanks for any input into this matter.
