I bought a Dosy TFC 3001 meter to check frequency on radios and then discovered it didn't do SSB so I had to buy a Dosy TFC 3001-S model to be able to check side-band frequency while transmitting. And regardless of the bad-mouthing Dosy gets I find it agrees with my good radios. I set my Lincoln II+ menu so the clarifier adjust both the receive & transmit and can with the help of my Dosy TFC 3001-S I can adjust my transmit to be Right ON. The Lincoln out of the box with the clarifier set in the middle ( 12 O clock ) Everyone sounds like Donald Duck, you have to turn the clarifier knob to 3:30- 4:00 to understand Anybody. Not everyone is off frequency so it must be my radio. It might have happened in transit but at this point I don't give a DO DO because I don't want to listen to Presidents BS & Excuses or passing the buck. I had enough problems getting my Mckinley problems fixed. Once this one is fixed I'm finished buying. I want to just be a USER. LOL
