RTTY issue (OT?)

Not sure where to go with this but hope someone here can advise.

MMTTY is working fine in DATA A (AFSK) receive is no problem and
transmit too provided I use 2125Hz.

I would prefer to use 1275Hz but when switching to transmit MMTTY keeps
jumping to 2125Hz. How to stop that?

Thanks
Martin, HS0ZED

Re: RTTY issue (OT?)

It will transmit on high tones, 2125....low tones, 1275 is for receive...no matter what receive tones are set, will always transmit on 2125, works fine.....

I'm not sure why you are using DATA A instead of AFSK A, but ...

If you don't want MMTTY to transmit on a different frequency from your
receive frequency, turn NET on - in AFSK, that will force the TX to follow
the RX. Also, you should tell MMTTY that your preferred frequency is 1275
Hz. To do this, set your HAM default to 1275.

A general rule for AFSK is: while S&P, turn NET on and AFC off; while
CQing, turn NET off and either turn AFC on or leave AFC off and use RIT
instead for off-frequency callers. Some software will switch the NET and
AfC settings for you automatically between run and S&P modes.

If you do use AFSK A instead of DATA A, you will have to change the K3's
PITCH setting to 1275-170 from the default 2125-170.

Re: RTTY issue (OT?)

Rich, Jamie,

Many thanks, all good now.
It was AFSK A, just got confused as after exiting the menu it says DATA
on the screen.

Of course it was (insert favourite name of some obscure person from
history) law that I found out about NET shortly after posting. I guess I
never needed that in the past as I had always used FSK. Will look into
doing that with the K3 in future I think.

I now have it set at 915Hz as that sounds even better when trying to
tune by ear. I'm not sure if there are any downsides to using lower
tones but it does seem easier on the ears and to tune by.

Is there a way to set it to default to that? Honestly I've never dug
that far into MMTTY. I'd like to set that up as part of my profile if it
can be made to work that way.

Thanks
Martin, HS0ZED

I prefer 915 Hz tones, and I ran into the same problem. I learned that
there are several things I needed to change. First is to change the HAM
default. This will work fine, UNTIL you choose another decoding
algorithm, like Flutter, and MMTTY will switch back to 2125 Hz.

To really solve this, you need to edit the USERPARA.INI file. With MMTTY
NOT running, open file with Notepad, Search and Replace
DefMarkFreq=2.125000e+03 with DefMarkFreq=1.275000e+03, and save the file.

When you restart MMTTY, make sure that 1275 Hz is set, and also that the
HAM Default is is 1275 Hz.

Re: RTTY issue (OT?)

Actually you need to edit *BOTH* MMTTY.ini and USERPARA.ini.
Replace DefMarkFreq in *BOTH* files with your chosen MARK
(also "PITCH" in the K3 for AFSK_A and FSK_D).

There will be one instance of DefMarkFreq in MMTTY.ini and one
instance in each [Define ] section (typically 10 sections -
Define0 - Define7 plus Define1025 and Define1026) in USERPARA.ini.
Note: some logging applications support 16 user configurations instead
of MMTTY's default of 8 - in those cases USERPARA.ini can have up to 18
Define sections!

I ran into this as well, but it's my understanding the MMTTY.ini is
saved each time the program is quit, and saves current settings. So if
you have 1275 set, it should be saved. Am I mistaken?

Re: RTTY issue (OT?)

It may depend on where the file is stored. If under \programs(X86) that
folder needs 'special' permission for software to write that the writers
must include. When that happens, it's best to install that type of
program under \MMTTY which does not have the limitations for writing.

Score this as another wonderful MS 'feature'.

HiScore this as another wonderful MS 'feature'.Yes it is. Permissions are made to prevent unknowedgable users and programmers from writing to areas which are under control of the operating system... The error lies with the MTTY developers. It should be in app data, My documents or a folder that MTTY uses or creates. Not in program files. 73 Tom va2fsq.com
