First off...hello to all and happy new year!
 This goes down as my first post here. I've been lurking around looking at the info on some qrp radio's trying to decide between SWL sw+20, and OHR 100a20m, as well as the DSW2 20m. Howevernthe waiting list on the SWL DSW2 is way to long for me to handle.
 So im wondering how does one go about designing a RIT kit for the sw+? What are the basics involved? I know there used to be a RIT on the market, and since this little rig has been talked about alot amoungst qrp's then I thought I'd take a stab at it and see if someone else had any idea's where to begin?
thx and 73's Smiley

I'm afraid I don't know the answer to your question.

I can tell you though that I have ordered a SW+40. Dave at Small Wonder Labs has given me brilliant service by answering my many e-mails politely and quickly.

He is obviously a very good guy. My opinion is that if you are in any doubt about buying from his company you needn't be.

Best wishes

One of the ARRL QRP books has an extensive article on
building and modifying the SW-40 transceivers, including
adding RIT.  I may have a copy around somewhere...

Since the tuning is done with DC levels, adding RIT
is not difficult.

And I think Dan's Small Parts sells a universal RIT kit.
