MMTTY RX bandwith exactly matching the RTTY signal. The brickwall DSP filter with sharp skirts

cuts everything off but the desired signal. It is clearly seen at the tuning indicator. With such a set up

you can even use wide SSB filters and still have pretty nice results overall. Obviously if you use other

filters, as well, it makes the overall selectivity even better.

Yet another positive aspect of that is the tuning easiness. It comes from the fact that only one and

only signal matches the bandwith. The moment you tuned to a station, the signal is already

readable/decodable and you only need a bit of fine tuning, if any.

As you can see, this profile is mostly just another contesting tool. It helps quick tuning and easy

decoding regardless adjucent QRM. And still, it provides the decoder with a narrower bandwith to

process, virtually one signal a time.

4.2 N1MM logger − RTTY − Operating the contest

While in S&P leave the NET button pressed if you are running deselect it.

AFC I usually leave off and tune by hand. During a contest the bands are usually to crowded. The

AFC is always trying to move and grab something you don't want it to.

AFC off during crowded contests (Disable: AFC On/Off with CQ)•

NET on during S&P, off during Running (Enable: NET On/Off with Run Change)•

To get bandmap/spot freq. correct (Enable: Auto Update TRX Offset w/Mark Freq.)•

Alt+T − Toggle TX/RX, the cursor will be set to the TX window of the active interface.•

Alt+G − Grab callsign.•

In N1MM

You will probably want the larger MMTTY window checked. If you use the small window you do not

have access to the MMTTY settings or the buttons.. Make sure you have whatever port that is going

to be used for PTT has the digital checkmark next to it..

4.3 QSO making tips with N1MM logger

During the contest the contest infoirmation like callsigns, exchanges are showing in the Digital

Interface (DI. This information has to be brought to the Entry window and split out over Callsign filed

and the exchange fields. Also transmissions have to be made. In Digital modes the normal behavior

as used in CW (using the insert key) and SSB (just type it in) can be used. There are some extra

possibilities in Digital modes which can be used (Callsign box in DI and GRAB button, additional

macros and hover mode in combination with the right click mouse button).

4.3.1 Using Hover mode:

With hover mode when you hold the mouse over a valid call sign it places the callsign in

callsign filed in the Entry Window. Where this works in use with 'Right click send Enter' is you

hover over the call then right click to plant the call and send your call when the station comes

back to you you click on the exchange to place it in Entry Window. Right click again send TU

and logs the Q. Right click, left click,right click and your done...

•

Note: Your own call is excluded from being picked up.♦

Hover mode is used in conjunction with the menu selection 'Rt Click = Return NOT

menur' which will will send a Return when right clicking in the DI RX window instead

of displaying a pop up menu

♦

4.3.2 The rate improver − Right Click = Enter not menu"

Selectifrom the settings menu in the Digital window "Right Click = Enter not menu". When not using

this setting then you need to give it a try. It could improve your rate greatly as your hand never leaves

the mouse except for the occasional difficult exchange. And your eye do not have to move far from

the Digital window either. Making a qso means:
