CB TO 10 METERS

[doctor]

WHAT is the simpest cb radio to convert to 10 meters for ssb or FM.
Surprising no one advertises to do it anymore.  I remember the wireman when he lived in the North did thousands of them for fm but no longer does this for many many years.

There is no "legal" or "type accepted" US CB Rig that has FM, so it would have to be added... not impossible, but not practical, either.  You can't use AM or FM on 10 M unless you have a General Ticket or above.  Tech/Novices have a little tiny piece of 10M phone space for SSB only from 28.300 to 28.500 MHz.

If you still want to be able to (albeit illegally) use the rig for CB frequencies when you are done, my first recommendation is to buy a modifiable HF rig from Icom/Yaesu/Kenwood/Alinco.  Second choice would be an inexpensive 10M rig such as the Magnum 257 that is easily converted to use both 10M and 11M frequencies.  Again, this is not legal, but I'm not commenting on the illegality.  I'm just saying it can be done.

Take care,
Rob

Get any 10 meter radio that already has FM built in such as: Galaxy, Connex, Superstar, Northstar, General Lee, Ranger, Texas Ranger, Magnum, Mirage, Stryker, etc.

I don't remember which of the above has FM capabilities, but quite a few do. Galaxy has some genuine CB radios but most of the Galaxys and the other radios above ARE NOT cb radios--THEY ARE ALREADY 10 METER RADIOS that cb'ers convert to use on 11 meters.

I haven't kept up with which freqs are valid for hams in a long time and I am not sure what would have to be done to get on those freqs but that would most likely be simpler than trying to get a cb radio to work both on the correct channels AND on FM.

I guess my point with getting a 257 (or now that I think about it, a better choice may be the 2950) is that they are non-channelized.  Most "export" radios are pretty much intended for modification for CB frequencies, and are therefore considered "CB's" by Hams.  Myself Included.  The "10 Meter" designation is just a thin disquise to try and not get busted for selling radios that are (*very*) easy to convert to transmit on 11 meters.

I have no survey data, but I would bet that over 51% of ham radio operators do NOT want channelized rigs.

I'm not knocking CBs here, just stating the facts.
I use and enjoy CB radios as much as anyone else.
<flame suit still on, 'cause I know here comes the lectures on type acceptance, etc. etc. etc.>

I think that if you own the radio, it is none of my business what you do with it as long as it doesn't hurt anyone!  It was either Madison or Jay that said you have the right to swing your arms as hard as you want to as long as your fist doesn't come into contact with my face! LOL











I think that as long as it is your radio, do whatever you want to with it as long as no one gets hurt!  Either Madison or Jay said, "You can swing your arms as much and as hard as you want to as long as they don't come into contact with my face!'

Also, the Supreme Court said, "The right to liscense is the right to regulate--No liscense, No regulation--Due to a lace of jurisdiction!".

Hi, and welcome!

Another member of this forum, TW, mentioned one time that it was a rare sight to see a "virgin" radio.

In your case, you would have the only known Siltronix 1011D known to exist as a stock radio if you didn't already have the CB band "enabled."

As I recall off the top of my head, the radio had the 11 meter band transmit function "removed" by a set of switch contacts on the band switch that disabled the TX feature when your bandswitch was set to the 27.0 Receive position.

If you can get the TX relay to operate on the 27.0 Receive band setting, your radio has been "converted." In other words, if you "key" the radio and hear a relay click, the "conversion" has already been performed.  If you don't hear a relay click on the 27.0 Receive band, switch over to the 28.5 XCV band and see if you can hear the relay click on that band setting.  That band was enabled for TX originally, so if you're not getting any relay "click", then there's problems.  

And when you do attempt this test by keying up the radio, press and release your PTT switch quickly!  You just want to hear if the relay is engaging, so as the old saying goes, "be REAL quick on the key!"

I don't know how familiar you are with this radio, or other tube type radios that require you to make adjustments to the controls associated with the transmitter's driver and final amplifier, but if this is a first time experience for you, then I highly encourage you to download the manual for this radio and read it carefully - especially the part about tuning the radio up while in the TX mode- before you even attempt to actually TX on this radio.  Your radio uses an 8950 tube in the final section.  It is very hard to find a replacement, and when you do, it usually costs more than the radio sells for in working condition.  Many 1011D's are sold for next to nothing due to a bad, or missing 8950 final tube.
  
Good luck!  Rick

Well I think this came from an old ham and It's not enabled. Any help would be apreciated.

Take a picture of what must be the only one still original.  Smitty has fallen over and needs to be set back up by someone.

Go here for a manual if you don't have one.

I need to see if Bennie has Secret CB Volume one up - I'm showing conversion info is in Secret CB Volume 1 page 46

I may have forgotten who said it (sorry Smitty   )

but

That's one line I will never forget.  Priceless.

Scratch that - I just pulled that Volume.  That is not the mod for the relay wiring.

I've got to dig into one of the archive filing cabinets.  Maybe someone else here has a write-up they can post while I dig... it's going to take me awhile to go through that stuff.  In the meantime, download the manual from the site I posted earlier so you'll have a schematic if you don't already.

Look behind the VFO enclosure. The shaft of the band selector sticks out the rear, and has a switch section mounted on it. There are two green wires on one circuit of this switch deck. Solder a wire across the lugs with these two wires. They prevent the relay from closing on the "CB" position as shipped from the factory.
