Thanks Rob, that's pretty badass. What do you use to align a receiver? I wonder if that tone generator on the website is any good or if the sinad meter is any good? Thanks

It requires an RF Signal Generator; the most expensive piece of gear by far. Usually $300/used - or more.

Yeah 10-4, it says for the new cobra 29 ltd alignment procedure to adjust l2-l9 for maximum signal on af voltmeter though... any thoughts or ideas??

Tuning/aligning receive in radios is not only the most expensive part of radio work - equipment-wise, it is also the most time consuming and difficult. A high-end RF signal generator is essential and unavoidable to the process. If the radio doesn't need to have the receiver tuned up, so much the better. The voltmeter isn't nearly as essential as a SINAD meter - which accomplishes the same thing as well as making sure that the signal isn't distorted from over-peaking - which is something that the voltmeter cannot detect.

I use that SINAD program and a Hp signal generator - which I was fortunate to find for $250.

Yeah bought a hp 8640. I'm just trying to figure everything out. Different radios call for different test equitment so I'm just trying to put all the pieces together and see what I need and what i don't really need. It's a little confusing, so I appreciate everybody's input. Thanks

Keep looking around on eBay and set it up to where you get notifications as well. This does help as sometimes late at night or early morning there are items that do go without notice. Also check CL constantly. I use the ALL FOR SALE, part of CL and it pulls up everything related to your search query. Just keep at it 805. You can find these items with the right timing. God luck aka keep your eyes peeled!!

Also it pays to check out garage sales as well. Seen a local here pick up a bunch of stuff by just garage sale browsing. Just some food for thought.
