Hi Jerry,
As discussed days-weeks ago here on the group, the 4k7 resistor between T/R pin
on the MB and the respective pin on the DG is missing on the PCBs. My fault
forgeting it when I designed the pcbs.
Is the resistsor on the base of Q23.
You may consider using other values till it goes to Rx. I remember Mark used a
47k.

Subject: [minima] Stuck in Transmit
I finished my MB and hooked it to the controller. I connected the tune
control to the control board and wired 12v to controller and 12v to the
MB. I wired a switch to the Fn control pins, I wired the BFO pin on the
MB to the BFO pin on the control board. I wired the T/R pin on the
control board to the R/T pin on the MB. I wired pin 11 on the control
board to the LPF pin on the MB. I left all the other pins on the control
board empty. My LCD on power up reads: A 14,200 2
USB TX 0
I have power to the TX side of the MB. But pressing the FN does
nothing. I can tune up and down freq., it changes from USB to LSB at
the right times. but won't come out of tramsmit. Any ideas.
