For the money you'd spend on a cb base station, you could pick up a kenwood TS50, TS430,TS440,Even a good TS570D all second hand in good condition, some will cost you less than a CB base,
Then there's the Icom 706 MK1/Mk2,Mk2g, Ic 718,Alinco dx70TH all will sound better on SSB,
most offer 100 mem channels you can easily programme your 2 favourite CB bands in, here its generally UK40FM on Mem 1 - 40 and 41 - 80 is FCc/EU/Cept frequencies. Mem 00 is generally put for 27.555 int calling frequency and most rigs can switch from Mem/VFO, I always at end of session leave VFO A on 27.555.000 USB and VFO B on 26.285.000 USB. Far better buy than any CB homebase export or otherwise.
Now if you want to do it cheap any budget Uniden sidebander and KL 203P amp will give just about same kick minus a few usefull features Donald Shockwave mentioned earlier, Madison, Washington, Stalker XX or Cobra 2000 GTL or 142 GTL. Along with the Kl203P or even many of the early Uniden sets
for Mobile, Jackson,Grant,Stalker 9,Cobra 148 GTL/DX/ Superstar 360 FM,
if you prefer the export versions,Madison, Washington and Stalker XX I believe were all sold as 80 ch exports in Europe with FM added too.
These are all far better propositions than a new Basestation and a lot less to lose if the wolf comes calling.
I personally use a President Richard (Cobra 148 GTL DX MK2 upgrade) or ss3900 with KL203p as its a lot less to lose than a base station and sounds as good as any HF unit when used properly, I've had HF sets, base stations and been busted, and trust me when/if the wolf visits you'll be glad you chose cheap with quality than expensive lacking it.
My whole setup including mobile antenna like hp 4000 or homebase sirio tornado including psu's would be between 180 and 250 quid maximum and can give any hf set up a run for its money both audiowise and signal wise, I sold all my expensive radios, they do a few extra things, but the one thing they don't do is give me a better signal or sound much better. And on the rare occasion I get out on air these days I get asked the same question repeatedly, what HF set are you running,
that can't possibly be a CB. I picked both the Richards and the ss3900 up for pennies with the odd fault, within minutes they were up and running, they sound as good as any hf set I've ever used and that's loads and they've never let me down and neither did the host of Jacksons,Grants and 3900's I had before them, they may not be fancy but they work, and work damn well at that.
Hf rigs are brill on 11m SSB right up to the point the FCC or our ofcom knock the door and walk away with them,Fucking lot of money to lose, been bitten once, ain't gonny make that mistake again when I can do it at a fraction of the price almost as well, if not better in the case of some HF radios. Pays to be shrewd when pirating.
