Fred, I got this off the news, I dont know if you care about it.

Mike



P.S. Only for you information, I know you would never dream of doing this to a

radio. :-)

Connect diode between top lead of D506 and lower right lead of

Q506 as shown.



Notes:D506 may be absent.  If not, remove it.

       Reset CPU if needed.

A friend did this and his IC-2GAT can now transmit 138 to 178 MHz (no

RF power output measurements were made).  He did no retuning, and did

not have to reset the CPU.  He used a tiny axial-lead glass diode,

replaced its leads with wire-wrap wire, and encased it in shrink-tube.

The operation requires a super-tiny soldering iron.  Observe CMOS

soldering precautions:Unplug the iron and ground the tip before

touching the circuit.



Remember:Except for MARS and CAP, it is illegal to transmit outside

the ham bands with non-type-approved equipment.
