I'm looking at some transverters for the microwave bands, and I've done some SSB contesting on 2m and 432. Current rigs are a ICOM-7100 and a pair of 706MKIIGs, as well as a 7200 (160-6, no FM), and a 7600 (HF + 6m all mode, but no VHF/UHF). Obviously I will downsize at some point very soon My rig drifted a fair amount on 432 during the latest contest, on both the 7100 and the 706MKIIGs. At first I figured the other end was using a tube transverter. Nope. We chatted about it this week and he had a similar issue with the 706MKIIG until he installed a CR-282 TXCO. Then the drift he saw went to about nothing. By drift, I mean, I was 20 below on the net frequency last week when I thought I had it dead-on 2m SSB (according to NCS), and kept upping the RIT until I realized it was also my TX end. By the end of a 1 hr net I had swung almost 75 total just to keep up with him. During a long contest, I'd be way off. A fan mod will help no doubt. So, frequency stability is always an issue with transverters. And I pondered, am I better of to get a dedicated 70cm and/or 2m all-mode rig so it doesn't have the huge multiplication problem? Would these potentially have better rx sensitivity? Looking at noise specs, I really don't know how to tell. But then, I see others that use a 10mhz clock, and I wonder if this mitigates things. Also, I noticed that both ICOM and Radio Shack made the CR-282, and perhaps some others did too. Any reason I should get one or the other? The RS ones are a heck of a lot cheaper. Seems I can go the TXCO route, or go with a dedicated 2m 432 rig. A few transverters I've seen (the Ukraine 220 one) use 28mhz IF.
