I may need some help tuning a notch duplexer I picked up...


My plan was/is to tune it using either a watt meter or my rtl-sdr's spectrum analyzer.  This is proving more difficult than I'd anticipated.








Anyone with a spectrum analyzer with a tracking generator would be a WONDERFUL help!





Please?

I'm a ham, but I haven't touched a piece of RF test equipment in decades (wattmeters don't count).

Try contact one of the RARC  members (Richmond Amateur Radio Club) at link and see if they can't point you in the right direction.

Hope that helps.

You know we have a Ham Forum here at ArfCom, right? **ETA: Never mind, just stumbled across your post over there.

For local help, I'd suggest getting on the repeaters around Richmond and asking around:

 145.1100-
 146.8800- 74.4
 146.9400- 74.4
 147.2550+
 222.4200- 74.4
 443.7125+
 444.8500+ 114.8
 927.0500- 100.0
 927.0250- 100.0
 442.5500+ 74.4
 145.4300- 74.4

I'm in NoVA  but have the equipment. Maybe could make a day trip in the near future?

Replied in the other thread before I saw this.




NoVA could be done on a weekend potentially.  A friends father is SUPPOSED to call me tomorrow with a lead on a local guy...  I'm not holding my breath though; friend is notorius for forgetting things.

After this reply, I'll keep it in the other thread, but yes, if that falls through, let me know and we can work something out.  It's a shame I didn't know sooner.  A bunch of us were down at the raceway for the hamfest/gunshow a few weeks ago!
