BARTG75 and 75-baud MMTTY

Written by admin On April - 26 - 2020 Comments Off on BARTG75 and 75-baud MMTTY

Okay. The BARTG 75 Sprint starts in 30 minutes. Our friend gets N1MM Logger running. Activates MMTTY as the digital interface. Sets MMTTY’s settings to 75-baud, and tests it out.

As always, our friend has skimmed through the instructions online… a great guide to 75-baud RTTY and N1MM using MMTTY is this section of the N1MM Operating Manual online.

Following the guide quickly, not worrying about the details too much, our friend finds that MMTTY sends and receives 75-baud RTTY just fine in S&P mode, but (Rats!) when switching to CQing — or Run — mode, MMTTY goes back to 45-baud.

“What the heck?” thinks our friend. “Maybe it’s time to quit ham radio altogether, or maybe this is a great excuse to go online and order that new radio and a bigger tower my wife said I can’t have.”

Don’t lose your mind like our friend above.

The fix is really, really easy.

There’s a setting in MMTTY that tells the software to go back to default settings any time you switch from Search and Pounce (S&P) to Run (CQing), or vice versa. Uncheck that setting, and you will retain all settings when changing between S&P and Run.

Open MMTTY’s Setup window (Settings menu item):

Uncheck “(MMTTY) Send HamDefault on Run to S&P Change”:

Press the “Save Settings” button and you are good to go.

All the best in the BARTG 75 Sprint!

How to set MMTTY to 75-baud

Oh, and if you can’t figure out how to change MMTTY from 45.45-baud to 75-baud, just open the Setup > Setup MMTTY menu item. Find the “Decode” tab on the settings window, and choose “75” on the baud rate pull-down.
