    For anyone interested, several Century 21 transceivers have showed up on That Big Auction Site Named After a California Bay.

    I'd like if I said I wasn't tempted, but I have too many projects as it is...

    I noticed that. There is an uptick of interest in the C21 it seems. Had seen one in years and now they're everywhere!

    Yes, there most certainly has been and I picked one of them up for $187 that came with 2 high quality Heathkit Coax switches, 4 Belden jumpers, an off brand 2K watt meter and a very small and old MFJ tuner. I believe that was a good deal but the Century 21 arrived needing a whole lot of TLC. Cosmetically the radio is pretty darn good although not perfect. Electrically the PTO was completely jammed up and it has an AC hum that is horrendous covering up nearly any possible chance at hearing a signal except a signal from my main station rig into a dummy load. The 21 transmit section does work 100% but the calibration is off about 100 kcs or so and I will need to align the PTO as well. Fast forward a few weeks and I completely disassembled and cleaned and reassembled the PTO and ordered all new electrolytic caps, and a bunch of .1, .01, .001 etc. I didn't order discs for the radio as I doubt they are bad. I did notice that all of the .1 and .01 etc. are weird striped color coded caps and many were cracked! That can't be good. With a few more hours recapping and an alignment I hope to have a nice performing 21 to place next to my HW-9 which is a wonderful radio. Also, is anyone aware of a mod to make the 21 input drive meter function as an S-meter? I would love to add that functionality. If so, please email me.

    Take care,

    It looks to be in pristine condition. Congratulations on the find.

    Peter, I have three Omni Ds and auxiliary PTO. Every single one of them had frozen PTO's TenTec must have used axle grease on the PTOs for lubrication. I found a very light silicone grease that works perfectly in the PTOs.

    I only used grease for the ball bearings and believe it or not used Mobil 1 synthetic oil for the rest and it appears to be a very happy mechanism!

    Has anyone ever replaced the vinyl covering on a Century 21? I bought a C-21 Digital that unfortunately needs the covering replaced. I bought a few options, but can’t find the original pattern/material. Any intel on this out there? They look pretty cool without the covering on by the way.

    However, I do want to return the digital one to the original covering if possible, or at the least, something very close. I’ve watched a few videos on technique but it’s really the material holding me up. I’ll update the thread if one of the Amazon options I bought work out to be close enough. If I can’t match the original, I might go...funky. We’ll see.

    I love my Century 21. The sound is very pleasant to listen to. It just has a warm sound to it. I find getting on frequency (zero beat) with another station easier with this rig than any other I've owned.

    My set up is a little different than this picture now, but the C21 is still on my desk being used regularly.

    I love the desk and lamp, the old (looking) clock and the old hand key collection.:)

    I have a Century 21, bought new in '77 or '78, I think. It was my first rig. I still use it occasionally.

    Be careful of the finals; the protection circuit is not the most robust. However, I believe the transistors are still available for not too much, but you will want to get a matched pair. I have a couple of sets tucked into the rig for spares.

    I also have the original Century 21 QSL card stickers that came with my rig, hehe...
