A reminder of the BARTG SPRINT 75 contest this coming Saturday.
Rules at:
http://www.bartg.org.uk/documents/Contests/sprint75/BARTG%20Sprint%2075%20Rules%20April.pdf
This is a short contest, just four hours, and uses 75 baud RTTY only. If
you've never operated 75 baud RTTY before, give it a try. It's quite
different. :-)
If you are using MMTTY either stand alone or with N1MM Logger, here are
some tips for setting up for 75 baud:
1. To change MMTTY to 75 baud, go to Setup>Options>Decode and select 75
baud. On the MMTTY window, do NOT press the HAM button during the
contest or it will revert back to 45 baud.
2. On N1MM Logger's Digital Interface window, under Setup>Settings, the
box that says (MMTTY)Send Ham Default on Run to S&P Change should be
unchecked, otherwise MMTTY will revert to 45 baud when changing to S&P
mode.
3. As a result of doing step 2, you should also do this step to prevent
AFC from causing your TX and RX frequencies to drift apart and not be
corrected on run change. On the Digital Interface window, under
Setup>Settings, the box that says (MMTTY-MMVARI)Turn AFC On/Off After
Run Change should be unchecked. After doing this, go to the MMTTY window
and be sure the AFC button is NOT pressed and that MARK is set to 2125
Hz or whatever default tone you are using.
4. After the contest, to return MMTTY to 75 baud, on the MMTTY window,
click the HAM button. Also, in the Digital Interface window, re-check
the two boxes from steps 2 and 3.
