[RTTY] Fwd: Re: Mark & Space - High Tones

[Robert Chudek - K0RC]

I owned quite a few TS-940's and TS-950's over the years. If you read 
the manual (TS-950sdx, page 36, top left column), it states the 
frequency displayed is the SPACE frequency. The manual is wrong. All the 
Kenwood's I owned displayed the MARK frequency.

Joe W4TV and I exchanged a few emails about this. I did additional 
testing using the WWV carrier as a reference. The radios in fact were 
displaying the MARK frequency on their dial. The Kenwood manual was 
never corrected, as far as I know.
