[RTTY] NAQP RTTY on NCDXF Beacon]

[robert]

Hi Wolf.
thanks for all.
What kind of a radio di you have?
I ask because I never have heard about a radio who sends DC to the rf
stages.
In the KAM+ Manual and in the arrl handbook, also in the manual for my
kenwood radio as well in the manual for the dxp38 modem I see the same thing
about the frequency from the transmitting starion.

Frequency sent = displayed frequencu +- the mark/shift tones.  the plus or
minus depends if you send USB or LSB.

in my case 14.100 + 2125 = 14.102125 KHZ
also  14.097875 + 2125 = 14.100 khz
soundcards use different frequency but it can be calculated.
I was testing this with my friend tonight and it did work this way.
Me transmitting on 14.09787 KHZ and he did receve me on 14.100 KHZ
by doing revers FSK I had to use minus and get the other sideband.

regards robert tf3tty...... 73
