Roger Beep fitted to MFJ-1263 microphone / rig switch

Some years ago I purchased a used MFJ-1263 microphone / rig switch with a view to using it as an ongoing test bed for my Roger Beep module.

Implementation

The Roger Beep module was assembled with 6 way 90° single row header pins for easy connection and disconnection.

RB-MFJ1263-01The module was built, tested and adjusted for audio output level and encapsulated in clear heat shrink. The cable was made from parts from ready made 3 way RC servo jumpers with the wires removed and inserted into more suited back shells.

RB-MFJ1263-02

Above are the connections to the MFJ-1263 to suit an Icom IC-7410. In this case, PTT is on pin 5 of the IC-7410 mic socket, ao AR5 was used to connect the RB module because it contains the PTT cross connect jumper (which you remove). RB PTT_IN and PTT_OUT connect to the lower and upper ‘5’ pins of AR5, and Audio_out, +DC, and GND on pins 1,2,6 upper pins. The use of 2 way connector for PTT_IN and PTT_OUT, and 1 way connectors for the others makes for flexibility to re-patch it to suit other radios.

It is VERY important to get these connections correct, pay attention to the sense of PTT_IN and PTT_OUT.

Adjust the module as described in the documentation and job is done.

I have a footswitch plugged into the PTT jack in the rear of the MFJ-1263, and have configured the Roger Beep Tap’nYap for 10min timeout so a tap of the footswitch locks the PTT on for a ‘yap’ and it can be released with another tap… or will timeout on a very long over.

Fitting to the MFJ1260 and MFJ-1261 would be quite similar.
