Tuning An AK-43?
11/9/2010 8:58:17 PMJohnny
First Atwater Kent I've ever touched. It does work but I can't figure out how to tune in stations. How do you do it? Unless it isn't working.

Thanks,
Johnny

Only two knobs. Volume and tuner. Needs wire antenna, optional earth ground. The correct speaker. Or an audio output transformer and PM speaker.

:Guess I should have worded that differently Warren. The big tuning dial is incremented from 0 to 100. I do pick up stations but how do you read this dial?

The 0-100 is a log scale. You would write down the station call letters when found, then log it on paper.

Sir Johnny . . . . .


I guess that the unit merely of yours has what is classified as a log dial scale for the tuning condenser, with
but a few variants, the usual dial marking was for the 0 being relevant to minimum capacitance settting of the tuning condenser.


Meaning that the highest frequencies . . .1700 . . . would be received at that end of the condensers setting.
The 100 was the maximum capacitance of the tuning condenser, and that would have the 540 portion of the BCB coming in.


On a few versions of tuning capacitors the numbering was reversed.


Soooooo . . . the idea was for 'ole granny Goodknockers . . . who knew little of this new fangled radio thang. . .to take a #2 lead pencil and pull out a Big Chief tablet and initially locate a received station and hang on long enough for station ID and then the writing down of the "log" number found on the scale, onto the tablet, and its associated station callsign / frequency data.


Initially one would be seeing pencil marks made on the dial scale proper, for favorites, until the stations were eventually learned.

:Thank you gentlemen! It all makes sense now. There is also a smaller knob just beneath the large tunung knob. This smaller knob turns the larger tuning knob but kind of intermittently. I'm guessing the larger knob is coarse tuning and the smaller knob is for fine tuning. Would this assumption be correct?

Also the radio appears to require more antenna other then the 6' piece of wire that's currently connected to it. I grab this wire and reception increases dramatically. Is this typical of this set? To require some kind of outdoor/indoor longer antenna wire?

The smaller knob is for fine tuning. It will have a rubber tire that engages the main knob. The tire wears out and starts slipping.

Go to an auto parts or hardware store and get some rubber hose of the appropriate o.d. and i.d. Slice a tire from it.

Longer the better for wire antenna. Ouside would be best. An earth ground too helps. For the fine tuning shaft, a sink faucet gasket is already beveled. Drill out the hole some to fit the shaft.
11/11/2010 9:21:42 AMThanks all! Got it.

:Guess I cant type this morning. Thanks for the input. Got it figured out now.
