Icom IC-245 Help	Reply

I've just repaired my IC-245 (an oldie and not a goody) for all mode operation after years of dedicated simplex use on packet. Now that eveything works, can anyone tell me how the duplex split is programmed? Thanks in advance. Mark

Never mind. I found the answer, and some other info. Turns out this is a much maligned radio. The analog is pretty OK but the digital parts are very primitive. Being among the first systhesized, PLL/VCO radios ever produced it makes one appreciative of today's technology. Mine works great though, in spite of sluggish and somewhat noisy VCO. 73

If the VFO isn't setup right (or has drifted with age) it will be noisy and sluggish. Mine (IC245) was given to me in a box and I had to reassemble it and fix the through hole problem (aka rivets). Re-alignment was needed even for PLL and once done it proves to be a sensitive and solid reciever with a good sounding 10W TX with no noise problems. If anything the front end is far less prone to intermod from pagers and the like! The only mod I did was to enable both upper and lower sideband for transverter or inverted sats. I also added a Ramsey PL tone board. I think the rivet problem killed most of these and many other radios using similar boards in that era, not the PLL design. The only thing crude about the PLL is no memories but it programs easy and fast and does even the odd splits well. Allison
