CB to 10

[Brian Carling]

Or better still leave it as an AM rig on 29.0 to 29.2 MHz

> If you don't have the articles I certainly do. Saved all that I could find

> convert them.
> 
> The 40m chnl HyGain/Cybernet PLL-02A synth chip was the favorite. Replace 
> one crystal and realign the synth, placing 29.6 mc on CB channel 30 and you 
> are almost there. Take the audio voltage off of the AF chip thru a 5K pot to 
> the synth test point and you have transmit FM. At that point you can leave 
> everything alone and slope detect the audio but you don't have any squelch. 
> If you want to guild the lilly, pull the Toyo AM narrow filter and put in 
> one that has a much wider BW and get a lim/dim chip (don't remember the 
> number but ECG still has the replacement chip available as of a couple of 
> years ago) for your audio recovery and there you have it.
> 
> I did about a dozen of them in the late 70s early 80s. Started with a bare 
> board, added S-Meter, RF gain, did all the cool mods, and put them in cases. 
> Also converted a bunch of HyGain/Kraco, Sears, etc 23 and 40 chnl CBs too. 
> Had a ball, gave most of them to friends. This all happened during my tour 
> in England. Worked a bunch of European/Asian/African DX with about 5 W and a 
> converted CB vertical. Great stuff, that!!
> 
> Lew Franklin from CB City International (check his website) has a whole 
> bunch of info, books and how-tos on putting these rigs on 10 FM, AM, 6M, 
> etc.

> OK, soon as I take my meds I'll be better.

> Psssssssst, Doc, wanna get rid of some of those old boards??
