Hi Fern, To answer the question, this is interesting reading: http://lists.contesting.com/archives//html/Amps/2003-12/msg00143.html The thread is quite long and was hijacked from the original subject. Only the first page or so applies to your question. This thread also has possibly useful info: http://lists.contesting.com/archives//html/Amps/1998-11/msg00163.html Mods.dk has a file listing someone's 10M modification. See http://www.mods.dk/index.php?ModelId=817&RadioRec=kenwood Note: You must first register before downloading. And, if you don't contribute, you're limited to 1 download/day. The official info doesn't appear on Kenwood's website. vy 73, Bryan WA7PRC > Fern wrote: > I have a friend with a kenwood TL-922A who can't > seem to get it working on 10 meters.
