Yes, thats rather easy. The Grant xl comes with a 5 pin factory. It's fun to check things out but if your going to send it to DTB why not just do it and get it over with. DTB can tell in less then a couple minutes whats up, check all functions, talkback?, echo?, clarifier open?, channels?, nasty signal on the scope says if it's clipped or not. DTB is a sharp dude, he will get it right.

Sounds like this clarifier was very fast and touchy. That pot was needed to get accurate control of it.
I like to take them out to 6KHz each directional 1/3,,,1/3 is dead at the bottom of the stock pots due to the stops. Not exactly but close enough for this reply.
Allot of techs run them way over this amount (6Kc-1/3 turn) to avoid putting in a 10KC shift off the PLL binary "1" pin onto a spdt switch so you can drop or raise onto the "A" slots. Every other "A" slot is 10KC up off the channel below, and the others 10KC down off the channel above. The reason is because the "A" freqs are 50KC apart and the binary pin 1 needs to be switched high or low depending. For instance: IF you are on say 3 and the 1 pin is low then you can fire the 1 pin up and add 10KC. IF however that pin is high already hot then you have to go to channel 4 and turn the 1 pin off. 3-4 is a 20 KC hop because of the "A" channel so the 1 pin stays either high or low instead of going on/off with each channel click of the selector when crossing over the "A" slots.
Each 1/100th of a volt = 10KC to the VCO so each binary addition of 1 provides 1/100V increase to the vco.
Clarifiers on the other hand load or unload capacitance to mixing crystal to allow it to move faster or slower thereby changing the freq and allowing that "slide" off center frequency.

Now.

22A is now 24 and was 40kc, I think.

Channelization sucks.

Very good post.

I preferred the clarifier to move 23 kc, helps alot with sideband and hitting 0's

A clipped radio can be used and not be nasty.

Sometimes, if the mod VR is jacked to full, it will sound no different that a clipped radio.

I got shipped to Washington, so I doubt I will be able to get the radio to him in the next three weeks...but I will get it there at some point...
