Jim, That duplexer is made in two versions. The 497-1-1 covers 136-150 MHz, and the 497-1-2 covers 150-174 MHz. Since the physical dimensions and weights are identical, I suspect that the coupling loop assemblies are different. The -2 duplexer will not function satisfactorily in the 144-148 MHz band, so tuning the duplexer is of no help until the coupling loops are changed out.
Contact RFS/Celwave Tech Support at [EMAIL PROTECTED] or 800-659-1880. The tech will gladly e-mail you the tuning instructions, and can advise you of the part numbers and prices of the items you need to convert your duplexer to operate on 2m. 73, Eric Lemmon WB6FLY [EMAIL PROTECTED] wrote: > > Looking for a tune up sheet for a Celwave duplexer, 6 can, VHF, model > 497-1.
