So should I go the RockMite route or wait and see how long it takes Small Wonders to put out the replacement for the SW+ series?
No.
I wouldn't hold my breath for a "new improved SW40+".
I'm still waiting for the "new and improved PSK Series Rigs"
that were promised when they were discontinued, what,
over a year ago now?
I have an SW40+ I finished a few weeks ago, works FB
if you're interested. (I got side tracked with another project).
It's setup for 30 KHz in the Novice Band, but changing
one cap and maybe squeezing a few turns on L1 will put it
wherever you want it to be.
My email is gud at QRZ.com.
