MT63 Testing


 

Hi Howard,

I tested the 12 Oct 2017 VS version, and the Icom goes into remote mode. Bandswitching, Mode switching, Transmitting
Everything works as expected, thats good!

But when I choose Digital mode, Start mode, Full test, TX send, the Icom does not switch into TX
When i push the TX button, in Digital mode, I can see the message:

DigitalModeAudio: WriteRadioAudio: Raising PTT

But nothing happens. I added the logfile to this message

73,

Rene, PA7R


 

Rene,

There are two ways to do PTT.
One is via a COM Port's RTS/DTR pins, the other is via a command sent out on a COM port to the radio? called CAT PTT.

In HRI settings, DigitalModes Tab, You should uncheck "Enable RTS/DTR PTT" to use the CAT PTT.

Hi Howard,


RTS/DTR is already off:

Rene,

You are right, I am not sending PTT CAT commands to Icom Marine Radios.

I'll get a new version made later today and post it at
/g/N3ZHSoftware/files

Howard

Hi Howard,

I tested the updated Java version from 21Nov.?
The Icom TX problem has been fixed, because when I Choose Digital modes, Full Test, the Icom goes into TX, so that has been fixed.
But
I have an interface with an external USB soundcard, and it seems that the audio signal routes to the default (internal) sound card.
Is it possible to add an option to choose the soundcard?

Soundcard options and right/left channel options are at the bottom of the "digital mode" window.

Hi Howard,


Oops,

I had to scroll my screen downwards to see the soundcard options. , its working now:


Now we have to to test if this text is being recieved by other stations. Any suggestions?

Rene,

I generally recommend "Left" rather than "Stereo" unless you need Stereo
for some reason.

MT63 is popular with FEMA SHARES.

It used to be popular in MARS, and I believe in a real emergency MARS
might see a need to fallback to MT63 with StationMgr.

I am not sure if MT63 is used very much by the general amateur radio
community.

There was a time when MT63 was quite common on the amateur bands. I made many contacts just above 14.100 using MT63 500L, 1000L, and 2000L.? MT63 is a very robust mode and is the fallback for MARS and other organizations, whose primary mode is M110A. MT63 is absolutely legal on the amateur bands for those with doubts. I am saddened that MT63 has all but disappeared from the ham bands. It is far superior and robust as compared to some still in use by amateurs.? MT63, in my opinion, is exceptionally good for keyboard to keyboard communication as well as EMCOM. I wish we could promote MT63 on the amateur bands. I would be very pleased to get back on that mode if there was some regular? activity. As always, I suggest keeping RXID & TXID turned on to allow others to switch to our mode/speed.

Best regards,

Gary,

Thank you for your comment. I know it is a problem in Europe to have a proper keyboard to keyboard communication chat.?
Most Radio?amateurs make only short contacts through Digital modes like?JT65A or FT8. I think the reason for this are the poor band conditions.
PSK31 was very popular, until last year when FT8 took over.

Its nowadays possible to chat with amateurs in Europe, but most chats use PSK31, and if conditions are really bad,?
Olivia 4/125 , Olivia 16/500 , or DominoEx8?is being used. I personally?use HRI which has native support for?Ham Radio de Luxe`s? DM780
Olivia and DominoEX? however are very slow modes compared to MT63

So that leaves us to EMCOM. But what I hear and see from the DARES ( Dutch Amateur Radio?Emergency Service)?organisation,?
that they use Winlink with the proprietary SCS Pactor II/III?modems, with primair?VHF and UHF frequencies, and HF NVIS frequencies?as backup
Its possible to use Winlink with the Winmor or UZ7HO Packet modem? on the Icom IC-M710, because John Wiseman has made rigcontrol support for the
IC-M710 in his BPQ32 node switch software, but I doubt if DARES uses anything but the SCS modems

Another way to communicate is to use PC-ALE, but I?have problems with the Icom IC-M710 &?soundcard options in the latest versions
v1.08 Build 1.0.0.0 Beta TEST BUILD #3.3 and?TEST BUILD #3.4.?
The good news is that I?have tested the (software)?MS-DMT ( it has support for?MIL-STD/STANAG) modem from N2CKH, on the Icom IC-M710 but this modem is being used for MARS communication purposes, and not intended for Radio amateur use

does anyone know what protocol will be behind the new winlink software modem ARDOP ?
i would not be surprised if it would be something based like MT63?

best regards
jaap


 

good day gentleman

a friend of my is daris region manager. DARIS does use software modems.?
backbone however is indeed packtor 2 and 3 modus via modem.?
they are of the opinion that hardware is expensive, and therefor will not ask there members to buy such modem, and are waiting for winlink to roll out the ARDOP software.?
