Just so you know it is a fair radio at best & only on SSB. They SUCK badly on AM. I just got rid of mine with the digital display & hope I never have another one. It drifted far worse than any radio I have ever owned or used. I don't know anyone who works on them these days & in my opinion it would not be worth the shipping cost having it operating at 100%.

It drifted far worse than any radio I have ever owned or used. I don't know anyone who works on them these days & in my opion it would not be worth the shipping cost having it operating at 100%. SIX-SHOOTER A bit harsh, but fairly accurate. I had one back in the 80's and yep, it drifted. But if you let it warm up for an hour or so, it would settle down somewhat. As for AM, if you ran a decent speech compressor into it and were careful in how you adjusted the mic gain and carrier levels, you could get it to sound acceptable. It had decent fidelity, but sounded fairly flat. Certainly not an audio screamer like a typical CB radio. |

Sorta the flipside of a Browning radio. Decent on sideband, if you can stand the VFO drift, but AM is more like playing a violin.
The receiver uses the same filter for AM receive as it does for sideband. As a result it's only wide enough to tune in just one sideband of an AM signal (along with its carrier) if you want it to sound believable. It won't pass both the upper and lower sidebands of a normal AM signal at the same time like a receiver that's meant for AM. And if the fine tuning isn't right, the carrier gets rejected by the receiver's crystal filter and the AM signal sounds more like sideband. If you tune it the 'normal' way for max carrier on the S-meter, all the high frequencies in the AM signal's two sidebands will be filtered out, making it sound as if you placed a pillow over the speaker and sat on it.
Mind you, once it's properly fine-tuned the AM receive will be okay, but only for that station. Move the next station's frequency just a little bit and you have to fine-tune your receive frequency to restore any audio clarity. The switch marked "Spot" on the front panel was meant to make this easier. But only so much. AM operators never match their carrier frequencies to each other closely enough to avoid having to reach over and clarify each station separately as they key up and talk.
This was a popular radio among sideband operators around here 40 years ago.
There were fewer choices at the time.
If you find a tech who is willing and able, (both) this is only part of the challenge.
It's not just the years, it's the miles. too. We found a lot of radios that were simply left running 24/7 to keep them warmed up. Most of the VFO drift is temperature-driven. An operator who didn't want to wait before using it would simply never turn it off.
This causes some extreme wear and tear inside the radio. The temperature of the "hot" components in the thing would just rise for the first 18 or 24 hours it was turned on. A radio that didn't get turned off would have component tie strips that simply crumbled, leaving the metal lugs and wires hanging in midair. The insulation at the ends of wires would darken and peel off from the heat. The exposed copper wire would be crusty with oxidation. Capacitors fail faster at high temperatures, and tubes would wear out in months that would last years if used the normal way only a few hours a day.
At 40-plus years old, the line between "repair" and "restore" pretty well disappears. If you had a radio with less than 5000 original miles on it, the cost to restore would be lower than for a radio with a lot of hard miles.
Making a 40 year-old car your daily driver won't be cheap, no matter what it was when it was new. This radio has no noise blanker. If you normally use a radio that has this feature, try turning it off to see if you have trouble hearing stations you're used to hearing. If turning off the blanker cripples the receiver you're using now, this radio will be a disappointment on receive.
I have to consider fixing up a Siltronix 1011 a bit like restoring a 1977 Ford Fiesta or Geo Metro.
Sure you could, but would you want to drive it after all that money is spent?
But it is, after all, only money.
At least that's what I tell the customer.

On AM the transmit audio sounds worse than CRAP. SIX-SHOOTER |
