I just today acquired a Swan 350C and have acquired a manual for the Swan 350. Does anyone here know what the differences are between the Swan 350 and 350C ??

Any and all insights appreciated.

Both of 'em drift about the same, but the C has been known to beat the non-C to the bandedge in empirical testing...

Okay, seriously, you can do a BING or google search for the two and find out the info you seek.

Well, SERIOUSLY, I have already done that and haven't found anything useful. Maybe YOU should do a search on the two, before making another stupid suggestion.

As far as I "remember" (and I was a Swan service center in the late 60s-early 70s, with factory authorization and training), the differences are primarly cosmetic. In fact, they may be "all" cosmetic. Basically the same rig, but the "C" looked different.

Both very "low end" rigs, compared with anything modern...but still great fun! Swan "modulation" on SSB is normally very good, and they're just fun to use. May not be stable enough for modern digital modes.

Thank you. That would explain why none of the webpages I have found really say anything different about the 350 and the 350C. I had a Swan 350 back in the mid-1960's and the Swan 350C I bought today does look a little different but the manual that came with it is for the 350. I did find some webpages that talked about the other models ( A, B, and D ) and differences between those models, but nothing to contrast the 350 and 350C.

Thank you. That is very helpful. That page did not pop out when I did my search, but now reading through the Swan 350 and 350C pages from your link I can see there are some differences. The Swan 350C is a slightly later model and seems to have several of the original tubes replaced with semiconductors.

BAMA has a manual for the a,b, and d versions but there is no reference to a "C" model! From the addendum in that manual the differences are primarily cosmetic. Also, the addendum is from Swan and, again, no references are made to a "C" model.

Thank you. I had found that page and inferred that the 350-A-B-D models were a much later vintage than the 350 and 350C, so the suffixes do not appear to be chronological. I don't know why the Swans are so confusing. I had no trouble getting good information on the other gear I have bought recently ( Drake R4B, R4C, T4XB, T4XC, Hammarlund HQ-170, and Heathkit HA-10 ) ( I am trying to re-assemble the stations I had during my early days 1963-1981 ... )

Lighten up.

Okay, here are some links that were found in seconds.

There you may not find out immediately, but might be able to get into contact with Swan users, gurus, etc. and possibly even some people who may have been involved with production, sales, etc. and get some real skinny. Not instantaneous, perhaps, but researching is often that way.

No results returned for "Swan 350C specifications" -- which in itself is a big clue as to what the situation may be.

I got the same results from Pete, the Manual Man, and, IMHO, this is pretty compelling evidence that there are no differences. The 350C was very, very popular. I had how log pages filled with contacts with someone running a "C".

Enjoy that radio! I never operated one, but those who did really liked them. And they sounded good!

Glen, these are the Cygnet (260 & 270) derivatives -- the 350a/b/d. The Swan 350C was the original design that was perpetuated throughout the 500 series.

ISTR that the difference between the 500 and 500C were the finals -- 6HF5's to 6LQ6's. I'm assuming that the 350 did the same thing.

Great Link with great pix!

Especially this one, of Senator Barry Goldwater's Corvette outfitted with a Swan 400 and Swantenna. Priceless! (http://www.angelfire.com/ny2/hamradio/gallery006.html)

The site won't let me post the pic here...

Did the Hon. Senator's views drift from time to time? <== Joke!

Some of the pages are missing, but not many, and what's left is great.

Thanks!

[edit]

Oh, man, THAT brings back something I haven't thought of for years. I took oboe (yes...oboe! I played in the MIT Symphony Orchestra) from a free-lance oboist (can one really make a living as a free-lance oboist?) in 1967 who was also a ham (how many oboe-playing hams can there be?) and he was wondering how to put a radio (I think he, also, had a Swan) on a Corvette with a fiberglass body. This is truly one of those "you can't make this stuff up" anecdotes!

Thanks for the memories.
