OK the updates. The issue is the 2201 is a 75.42 Mhz IF and most of these alternates are 35.42. Hmmm sounds like adding 40 Mhz gets you the answer. Thats exactly what I did with the odetics converter from Pete L. Took 10 Mhz from 2201 4 X to 40 mix with 35.42 buffer and send to the 2201. Locks like a champ. I feel the RF chain is not all that reproducible and could be improved. So though it works through Dougs support I have been trying out the novatels that also have a 35.42 IF. They have one other nice feature a derived 40 Mhz pecl signal. So first attempt uses a soic pecl to ttl converter driving a sa612 mixer and then a buffer... However this requires a tap off of the 35.42 Mhz saw IF filter and then a lot of gain. The Novatel also puts out a much amplified 3.90Mhz IF. This created a 3rd converter approach. 3.9XX + 71.111 Mhz mix and deliver. this is a very nice approach but at this moment I have to use a significant lock sig gen for the 71.111 Mhz. Last item with the 2201 there really is not a C/N ratio or signal strength to have any clue if A is better then B or C. Makes it sort of tough because B and C do work. I just suspect they are worse then A. Regards Paul.
