need help 10 m mod for navaho ssb
hello, I have been out of the scene for 5-6 yrs but the recent hamfest cured me of that! I purchased a lil dual band ht htx-420 to be exact, and hooked up to my ole base antenna and got hooked again. anyways, I am a ham that enjoys dx more than anything and with the economy the way it is I just cant afford to have the equiptment that I need.I do however have a friend with a navaho ssb cb that he will give me if i want. I have done some pll mods to some old ge radios in the past, but i dont know if I would need a crystal kit or if its pll. if anyone has any ifo on this, it would be greatly appreciated. I need my dx fix lol. I do have an external freq counter, so that will help me alot. or if by chance anyone is selling a 10 or 6 meter rig very reasonable, I would also be very interested especially something like a kenwood 520 or something like that, I could afford up to $150 and I'm not concerned with looks at all, only if it will get me on the air. thanks all 73's KI4ELC shawn email: firstname.lastname@example.org

Reason: sorry for the double post
What is the model number of the radio?
Sounds like a TRC-457, 458, or 490 to me.

ke5wdp....please keep your comments to yourself
do I not have the right to alter a cb to operate on 10 meters?? last time I checked, I do have that right! if I were not a licenced ham operator, I could see your concern, but I was under the impression that qrz forums was to help other hams, and isnt this the mod section?? you are the type of ham that we dont need in our community!
i belive this is the model number, i havent actually got this radio in hand yet, but it has been offered to me, I just havent picked it up yet. trying to get a head start
Converting a CB to 10M is a great project!
Without knowing your skill level, Her is a rough idea of what you are going to have to do.
Obtain a service manual/schematic.
Study same, and determine the frequency scheme used, I start by calculating the frequency of EVERY oscillator in the rig on both TX and RX.When you understand the CB frequency's, you can then calculate where they will need to be for 10M.
Then test and align the rig on CB, to verify it works ok.
For the actual conversion, you will have to change one of the oscillator crystals, and then do another COMPLETE alignment of the rig, as a minimum, you will need a voltmeter, a wattmeter, and a signal generator to align the RX.
When the rig is on 10M, then you can modify for more frequency's, and add fine tuning.
If you have never aligned a rig before, I would advise you to find a LOCAL elmer who has.
Now my mistakes travel at the speed of light!

I didn't know we are allowed to practice illegal activity on this forum. I was raked over the coals here in this forum over my past illegal activities.
I got a great site for you to go....I am a member there and are great people!!!
Sorry you got raked over the coals. It happens.
Hams are allowed to use modified CB radios. They can no longer be used as a CB legally after modification.
