Re: V5 Rcv cuts out

 

Hi,

If the relay passes only small signals and nothing else, then it must have some kind of contact maintenance current -- even high quality ones need this.

Here is a service bulletin for one of their transceivers needed adding on because they forgot to do this:  https://www.qsl.net/wb4kdi/Kenwood/TS-430S/Service%20Bulletins/asb0902.html  The bulletin has info on both cleaning the contacts and then setting up the circuit.

The Icom IC-730 also needed a circuit added on for the pre-amp relay which went out too because it switched only small signal and had no maintenace current.

I'm sure such a circuit could be added on to the ubitx if desired.

73,


Mark.
