Re: [Drakelist] DRAKE R7A problem on change frequency band.
It could also be as simple as the molex pins on the digital readout board. Pry the board out a bit and re-seat them. Look the pins over for any cracks in the solder. Good luck!

Re: [Drakelist] New and R7 SMeter Query
Thanks for all the input, gentlemen. I have made some headway. Especially after I discovered the meter face had a good static buildup! I got it as close as possible and adjusted the IF gain to match the modern rig. It's all relative... But, if it reads anywhere close to what I consider normal in the region up to S9 +20, it is haywire above 20 DB and now CCW RF gain is only +40. I always considered (and found) Drake transceivers to have 5 DB between S units and great accuracy above S9. I there any chance the R7 was meant to reflect a different standard?

[Drakelist] New and R7 SMeter Query
Hello folks. Not sure how I had missed this list until now, but have seen some good info in the archives. Had a few Drakes slip thru here over the years. Still have a 4A line on the air and enjoy being the protector of a relatively nice 1A. Don't have a large collection, but enjoy most older radios as well as the new. At any rate, recently added an R7 to the collection and have it going rather well. One thing has me stymied and it is the S Meter set up: If it is aligned according to the manual, full counter clockwise on the RF gain only raises the meter to 60 DB and not full scale. Is that anything close to what anybody else sees? R4A calls for a setting of full scale on the sens setting. Otherwise, it seems correct. I can push it above 60 with the sig gen. S9 is 50 uv and the steps above and below S9 are correct. Just wanted another opinion before I replace the case. Neat radio. Been on the wanted list for many years.
