I looked at Ron's photos, and have confirmed that his Q202-G duplexer is, in fact, the later model with integral notch tuning capacitors. Converting that duplexer for operation at 2m may require nothing more than replacement of the RG-213/U harness with RG-400/U or RG-214/U cable, being careful to have 14 inches between tee centers. I have tuned three such duplexers after modification, and their performance is very good.

I have sent you a couple emails containing pictures of the duplexer as you requested and can send anyone else interested the same. We are trying really hard to complete this project as hurricane season is now upon us and this repeater will also tie into The intertie to include Skywarn in Peachtree city, GA. Please keep the response coming as all info is greatly appreciated. Worst case I guess is we send these back to Sinclair to re-tune or simply replace with another set. Either is an option but neither would be better. We would love to have these re-tuned locally just to save on costs as with most in today's economy funds are running low. 73's N4SFU/Ron
