Great rig,
858 chassis can be freq modded to go about anywhere.
The board is one of the best in SSB, not much of an AM talker.
Check out this link.
I have done some of the mods and they work as advertised.
Great audi on SSB with stock mic.
Fantastic recieve.

i have no complaints about my old 139 xlr. it had alot of extra channels and worked like it should. if you can get one that isn't all hacked up for a good price, i say go for it.

They are nice radios for what they are but beware they are old and if there were no updates done as far as Capacitors ETC you can be in for a real treat. You may have alot of hours in on it before it starts but I gues I would find a good tech and have it gone through or checked over to avoid any potential problems

They are cool radios I had one that was damn near mint condition with no mods I just alligned it for SSB and it was super but I sold it to a local friend of mine and said dont let anyone mess this up its pristine I told him not to resell it Ide buy it back . He let his buddies tear into it and the radio is now junk it made me sick it looked and smelled new!!! Just find a good tech that has the knowlede to set it up or do the repairs because theres so many trailer park / apartment Golden Srewdriver experts out there that its easy to find yourself holing a paperweight when there done attempting to perform their magic.

You can send the radio to radioactive radios and have them do a supercrackpack mod to the radio......that'll only be about $80. LOL!

Wish I could get a deal like that...but every time I DO find one, I don't have the money for it!!

I got mine a while back, it's unmodified (main reason I bought it-as little as I know about radios, I DON'T want to try to "fix" them!!) Still waiting for the new final and driver transistors from eBay (cheaper buying from China, but wait about a month for shipping) so I can't comment on how MINE works (yet) but the people I've known over the years who had one (including one who had BOTH CB and 10 meters USB on his-wonder how he did THAT??) haven't had any problems...actually, one guy I knew complained of bad TX/RX on AM (but it SCREAMED on sideband) but who talks on AM anyways??

As with ANY 30+ year old radio, you'll want to have someone go through it (check the caps, tuning and alignment, ect) before you make it a daily talker, and BTW, if/when you DO have the caps replaced, MAKE SURE to use AT LEAST 25-50 volt caps (I've heard that was one of the weak spots-Dynascan only used 10-16 volt caps!) There's also a few service bulletins for the 138/139 XLR that you can look up on CB Tricks.

As mentioned before, make SURE it hasn't been (or won't be) subjected to the dreaded "golden screwdriver" (no "extra" knobs/switches/holes) or AT LEAST know that the person who does/did it knows what they're doing (the local "tech" in my old 'hood was FCC licensed-wish I could find one here) or you're likely to end up with an expensive paperweight...know one guy who had his 138 XLR channel modded by a guy at the local truck stop recently, since then it would blow the in line fuse every time you turned it on and keyed it up!! And of course, he hasn't seen that guy since...

Seems like every "good" radio out there gets screwed up sooner or later...
