Programing the NUE-PSK Digital Modem 29 - May - 2012

Just wanted to jot a quick note about how easy the NUE-PSK Digital Modem is to program – once I read the directions!

Mine has been back for each update and has the USB add-on with the RTCC (Real Time Clock Chip) feature.

It has been upgraded to Version 5, which added a morse key jack and full CW features.

Experimenting with Winston K9CFVR (we can drop the /AG as he is now listed in the FCC database) we hand typed everything. Did it the hard way and really didn’t get around to consulting the manual until after we were done.

It is a tribute to the ease of the NUE-PSK Modem that we were able to run PSK-31 at all given our caviler attitude to reading the directions.

I now have the NUE-PSK loaded up with a Config.txt file that has all my macros in it – paralleling what I usually program into MixW or fldigi when operating.

Technique was a quick couple steps:

  1. Download the Default Config.txt file from either the NUE-PSK itself, or from the website.
  2. Edit the file with a plain text editor.
  3. Put it back on the USB Thumb Drive.
  4. Use the NUE-PSK’s Load Config feature to Upload the edited Config.txt file into the Modem.
  5. Let the Modem reboot & test.

Took all of a few moments to do and the machine is ready to go.

Here are my macros as currently implemented:

MACROS FOR PSK AND RTTY:

Macro F1:  CALL CQ : CQ CQ CQ de <MYCALL> <MYCALL> <MYCALL> pse k

Macro F2: ANSWER ANOTHER’S CQ CALL: <THEIRCALL> <THEIRCALL> de <MYCALL> <MYCALL> pse kn

Macro F3: ANSWER WITH REPORT: <THEIRCALL> de <MYCALL> UR 599 599 into EN64dc EN64dc Manitowoc, Wisconsin – Name is Steve Steve HOW COPY? <THEIRCALL> de <MYCALL> kn

Macro F4: ANSWER WITH OPERATING CONDITIONS: <THEIRCALL> de <MYCALL> Full Print – I am operating a NUE-PSK Digital Modem (no computer) with a SGC-2020 Transceiver at 8 watts with a portable antenna. A very small portable setup from my “Go-Kit” that I am testing today.  BTU <THEIRCALL> de <MYCALL> kn

Macro F5: ANSWER WITH A BIT ABOUT ME: <THEIRCALL> de <MYCALL> Thank you for the information.  All copied.   I am good at QRZ.com and you can find more about me at http://k9zw.wordpress.com BTU <THEIRCALL> de <MYCALL> kn

Macro F6: REQUEST AN EMAIL CONFIRMATION: <THEIRCALL> de <MYCALL> Would you please email me a confirmation of our QSO.  I do eQSL and direct QSLs.  Sometimes LoTW when I feel brave!  My email is k9zw@mac.com  BTU <THEIRCALL> de <MYCALL> kn

Macro F7: SAY 73 AND SK: <THEIRCALL> de <MYCALL> Thank you for the QSO – Godspeed and 73 – Hope we do meet again!  <THEIRCALL> de <MYCALL> SK..Sk..so

MACROS FOR CW MODE:

CW Macro F1: CALL CQ: CQ CQ CQ DE <MYCALL> <MYCALL> <MYCALL> K

CW Macro F2: ANSWER AND REPORT WITH INFO: <THEIRCALL> DE <MYCALL> TU FOR CALL UR RST 5NN 5NN QTH Manitowoc, WI, OP Steve HW CPY? <THEIRCALL> DE <MYCALL> kn

CW Macro F3: CONTEST QUICK TURN-AROUND:  TU QRZ? TEST DE <MYCALL> TEST K

CW Macro F4: SEND MY CALL SIGN: <MYCALL>

CW Macro F5: ANSWER ANOTHER CQ:  <THEIRCALL> <THEIRCALL> <THEIRCALL> DE <MYCALL> <MYCALL> <MYCALL> kn

CW Macro F6:  BASIC INFO: <THEIRCALL> DE <MYCALL> RIG HERE IS SGC-2020. USING A NUE PSK MODEM. HOW DOES IT SOUND? <THEIRCALL> DE <MYCALL> kn

CW Macro F7: TUNING AND TESTING: TESTING TESTING DE <MYCALL>

I’ve left out the transmit on/off and control characters on my cheat-sheet notes, but they are there in the Uploaded Config.txt file.

A little manual reading a pre-use programing sure makes the NUE-PSK Digital Modem one slick little device and a perfect companion to the SGC-2020 Transceiver!

Is this a special program to work with your Flex? If not, how do you use the program with the Flex PC?

I’ve been using the old FREE Digi-pan PSK31 for years, very simple and easy to pre-program macros. I bought MixW and Muitipsk to keep going back to Digi-pan due to simplicity. (I still us and will continue to use Win XP so I do not know if Digi-pan will work with 32 bit Win7 – I suspect not.)

The one biggy – ALL NEW Digi-OPs need to know in doing any digi-modes…. Setting your radio up for digi-modes. I found that leaving the mic gain/filter the same (as in SSB) will cause excessive splatter – and the wrath of other digi-ops. There is no easy way to set this output other than to use another radio and listen to your signal, as mic ‘monitor’ does not correspond to the actual signal out.

I set my TX filter for 1.8-2.1KHz, and the mic gain below 50%.

Don’t forget when you go back to SSB to readjust all or you will have a very weak signal.

Hello Dale N6JSX

Thank your for the questions – I’ll try and answer them in order.

The NUE-PSK would be useable with the Flex-5000A using the same cable as a Yaseu rig. I’m guessing but I think cable Type-16 would be one that would work.

As the Flex-5000A already has the audio and all other digital needs in a computer (the one running PowerSDR) using outboard hardware like NUE-PSK would likely be for testing or experimenting.

I’m using the NUE-PSK modem with my SGC-2020 transceiver as a “go-kit” type configuration.

On Digipan it’s most recent versions are 32bit and have been renamed Multipan. The original program hasn’t been updated much – 2004 seems to be the last, and the 32bit version seems to be in limbo in a beta version for some time.

Presently with the Flex-5000A I use three digital programs, MixW 3.0, fldigi (Windows version) and JT65HF. The special purpose JT65HF does JT65 QSO’s only, and the other two are largely interchangeable. I’m rather positive on what I am seeing in fldigi and a couple small items adjusted would really make it my first choice. The new MixW 3.0 is really a fee-based update to MixW 2.18, an upgrade I did having a lot of comfort with MixW from the user aspect.

You are absolutely right that you need to properly configure your rig when running digital. One great way is to use one of the dedicated PSK meters to check your signal. I’ve been using Clint KK7UQ’s PSK Meter for about 5 years now, and it is a really aid. Article at this LINK.

Some good notes on setting up a PSK31 Station expanding on your reminder about levels can be found HERE.

All best and 73
