"or to push to 52MHz for the amateur 6 meter band)." Mike, Did I understand this correctly? The 42 to 50 split can be pushed to the 52Mc repeaters without modifying the front end? I have a U51LLT Motran that I would like to put on the 6m ham band, but digging into those front end coils has scared me off a bit (there's too darn many of them). Would be great if it could be pushed to 52Mc without mods. Also, someone on here mentioned the channel elements. My channel elements for that radio were lost when I moved to this house and I haven't been able to find any. If there are any spares floating around for the "L" transmitter and "L" receiver, either one or two channel, I'd sure like to buy them. The ones that were in there were TLN1022A and TLN1020A, but I'm told that the TLN1080 series will work also. If anyone has anything, please email with what you have and price. Thanks, Tom KB5DPE
