I repair and redesign ham radios and it is with great pleasure to see you do your work. I am a ham and a scientist with 50 years in the RF world and you are an inspiration to so many I believe.

[@miketaylor2197]

Could you design a noise blanker circuit for a 1011d? I have lots of power line noise and can only really use mine on am when it rains

Miks radio repar your are good at restoring vintage cbs and vintage shortwave receivers

[@Ben-rj7xs]

I had one of these old siltronixs they had a drifting issue but when they worked good they were great radios

[@TheRadioShop]

Good job Mike. I have 5 of these I need to restore one day. Always something to do. Thanks for sharing.

[@9291wolfman]

The Radio Shop buddy I sent you a email about working on one of my Siltronix radios about two weeks ago I used the email address on gokarters

[@johnkaveski7953]

love how you treat the radios you work you go the extra mile

[@TheMajictech]

Looks just like the one I grew up with, and sadly sold a dozen years ago.

[@mark5862]

This is basically a 10/11 meter version of the Swan 350A. Most likely these were targeting the illegal CB market. Great solid radio, and in my opinion underrated. I owned several tube rigs including Drake, and The Swan 350A is my favorite. Solid old rig.

Nice work i had a kenwood TS-830s beautiful radio Heavy... Beats me everyone also says you off frequency? How do i know they not 😂

[@soylentgreen6476]

Great job! Thanks for sharing.

[@KA5IVR]

That radio looks familiar... Thanks Mike!

[@624radicalham]

Mike you read my mind as I've been meaning to ask you for more camera time of tuning through the channels, in this case the band. What you did here please do for your future videos when you finish them. Even if there are no signals, the static sound allows us to hear the difference in receive and just how sensitive the earlier models like Motorola were. Even the click of the switches helps out in making a decision to buy a certain radio. Keep it in mind brother!

[@AERVBlog]

Back in the early 70s when I got my FCC license I was hired by a CB shop in Atlanta Ga. It was my job to sign off on the radios before they left the shop and also to fix Johnson White Face tube types. I was wondering if you have ever worked on those. Quick story, somewhere in my first week I had just replaced a final and the grid coupling cap and as I turned it on the boss who had been standing behind me holding a 4 foot 2X4 up with his foot on the other end let it go. The bang when that thing hit the floor made me jump completely off my stool and then I had to go home and change underwear. I love your videos. Take a look at mine if you have a few minutes on KZbin, AERVBlog. Keep up the good work and thanks.

[@mikesradiorepair]

I actually have 2 here currently for restoration. A White Face and a Black Face. I have done several of them over the years. I love them. Simple no frills design that's built like a tank.

[@AERVBlog]

@@mikesradiorepair ahh! The good old days. I went on to radio engineering and kind of got stuck there for 30 years. Thanks again for the videos.

[@Philbytronic]

I used to have a 1011C. It looks the same as that one. It would "drift" a lot, though.

[@squidextreme2000]

I just got one and someone used there golden screw driver in it

[@richarddalton5191]

Siltronix/Swan are drifty,but I just love boatanchors

[@Hathorr1067]

Sillytronix. If I remember right, the factory considered drifting a feature.

[@johnkaveski7953]

that radio is worth putting money in

[@jkbish1]

i recently bought a Siltronicx 1011d I thought I could use alternating current from the wall to power it. The rear panel has two outlets which are marked 117 volts.. I cannot find a plug to put on a line cord for these plugs. Does anyone know where to buy such a plug?

[@martyham10]

Didn't they used to call that special paper "fish-paper"?

If you dont mind me asking Mike,, about how much did it cost the customer to do this work

[@winchestertactical4656]

Hey mike do u still do these radios i have one in very good cond i would like a tune up and re alignment done on as well as check all the tubes.

[@sidneyarnold191]

I have one but don't have an antenna. What kind do I need?

[@johnkaveski7953]

mike were your at it's cold in the winter

[@jkbish1]

On a lark I bought one of these. Yuck. The old white capacitor(100 35v) on the underside of the 8950 has a burned spot on it and the 4.7 ohm resistor next to it is burned to a nasty crisp. The resistor is clearly toast and I'll have to figure out if the cap is bad...probably is? The rest of the caps are all original but none "look" bad. I'll need to figure out how to test those. I am encourage to see at least two of the caps in you photo appear original. I tried to find caps on the web. Mouser seems to sell them but if I buy all the caps , the down total looks to be a few dimes under $100. Not sure it is worth the time and money it will cost to bring this back to operation.

[@Dirtburglar254]

I have one of these and when I turn it on it’s keyed up as if you hold mic trigger on. I tried different mic wiring configuration to see if miss wired but relay still closes upon turn on. Any suggestions?

[@Greg-et2dp]

Miks radio repar the owner vintage siltonix Comanche CB radio model 101 1d is awesome

[@robinpetitpas996]

Hi Mike i have a 1011D thats needs to be looked at my audio is all garbelled on transmitt (HELP) Rick P Pepperell,Ma

[@miketaylor2197]

Is it garbled on AM? These can difficult to make sound good in that mode. First off, avoid power mics. And keep the mic gain on the radio on between 9 and 11oclock. Any higher will cause distortion. They are really nice sideband radios but just not the best on AM. They'll never be loud like a Galaxy in that mode because you are basically talking on one of the sidebands with the carrier balance purposely mistuned to insert a carrier. Also on AM,keep the plate current at or below 120ma or you'll cook that expensive 8950 final tube

[@Centar1964]

I have a SWAN 270 (10 to 80 meters) that is almost identical to that radio...Mine runs 180 watts input does this one also do that on CB freqs?

Sent you a message about your crazy spurring galaxy radio and how to fix it, if you still have it make a video of it. Thanks

[@bobkozlarekwa2sqq59]

By chance, do you know where I can find a schematic for the ECI PORTALAB? This is the chrome plated version, I believe the earlier version of the one bearing the Courier name.

[@JA-fy1bn]

I would really like to have one of these in minty condition. Do you have one for sale and if not, if I can find one, do you still work on these?

[@vu3mes]

Hi Mike do you repair any watkins Johnson radio. I have an 8718 gone qrt.

[@southeasttnforgeandironwor5673]

I really enjoy your videos Mike, they are very informative and have helped me out! I have a question.....I have two of these that have a 50 watt carrier no matter the mode or adjustments. Is there something I should look for ? I can’t find the issue on these, one is a C and one is a D model.

[@scottlitz3199]

Did you set the carrier balance on the bottom of the radio ? Just a thought.

[@matthewdavies2057]

Q: Mike I have been looking for a good older ham rig to listen to HF with. Something like an ICOM R71A. All the less expensive units I see on eBay have major problems. What models do you like from that era? I'm a ham so a transmitter is okay too but not required. Thanks.

[@thevacuumtubejunky9774]

Curious if the Comanche 101 1d is a spin off of the Yeasu FT-101 series transievers?. Thanks for sharing! Kind regards, Eric Dee.

[@mikesradiorepair]

No, Siltronix was a spin off of Swan. Swan made the 1011 and apparently the amateur radio community gave them hell because it was obviously a CB radio. The FCC was also none to impressed. They made a spin off company Siltronix to sell this type of product while protecting the Swan amateur radio company.

[@thevacuumtubejunky9774]

@@mikesradiorepairThank you for your reply. Very interesting, that's a really nice looking transceiver. What is the Tube compliment (Finals) for that rig?, and are those radios hard to come by nowadays?. Kind regards, Eric Dee .

[@mikesradiorepair]

They use a 8950 horizontal deflection tube for the final. I wouldn't say they are hard to find. FInding one in mint condition may be a little hard.
