Re: Sticking TX/RX Relay UBITX V 6

While I am new to the forum and have not heard of that issue- you may want to look at the voltage on the coil and make certain that it is not holding the relay into the TX position. Others, more knowledgeable can likely chime as to in whether that is even a possibility. ? Dale W4OP ?

Subject: [BITX20] Sticking TX/RX Relay UBITX V 6 ? I have been trying to make CW contacts on 40 meter over the last few weeks, only to find that the TX/RX relay started sticking in the transmit position?after sending CQ's.? This last time I thought the?relay had give up the ghost.? I finally got the relay back?into the receive mode.? Here is my questions:??Is the UBITX V6 schematic on the HF Signals website correct?? As I read that schematic the TX/RX relay is K3?? Is there any remedial action that I can take to fix the relay or is it a remove and replace only option?? ? The reason I ask is in reading the many group post, I found one that said the HF Signals UBITX V6 schematic was wrong do not use.? If this is the case can someone direct me to the correct UBITX V6 schematic and the location of the TX/Rx relay on the board.?? Thanks much for the help,
