Receive digital text and images via 144/440 MHz FM

kd9xb
 

Hello friends,

On 2 meters and 440 MHz FM, in addition to our usual voice QSOs, we can also receive and transmit text and images, using software now available free to the amateur radio community.

A few years ago, I conducted a digital "after net" following the Tuesday evening Arlington ARC 2M net. I'm planning to resume these digital transmissions (digital via analog FM, actually). To decode the digital modes, and perhaps even to try transmitting them yourself, please download and install the Fldigi software ...

http://www.w1hkj.com/files/fldigi/

or here:

https://sourceforge.net/projects/fldigi/files/

For decoding, all you need to do is get the audio from your radio into your PC. This usually involves a patch cord from your radio's headphone or audio output, into the mic jack of your PC. You can also try "acoustic coupling," which can be accomplished by placing your HT's speaker next to the mic on a laptop.

Then configure Fldigi for the appropriate audio device. If you have a newer transceiver with a USB connection, Flidigi might recognize your transceiver as an audio device.

When using Fldigi, select RxID at the top right. That will automatically detect the mode being used, and the correct audio frequency (usually 1500 Hz).

If you want to transmit digital modes, an interface such as the SignaLink or RIGblaster is very helpful, although if your transceiver has the aforementioned USB connection, you may not need the interface.

I recommend Fldigi for relative east of use and installation, but you might also want to look at MultiPSK ...

http://f6cte.free.fr/index_anglais.htm

MultiPSK has some modes and features not included in Fldigi.

Android apps

There are also apps for Android that will decode the modes.

AndFlmsg encodes and decodes, so it can be used for transmitting as well as receiving. And it has recently been updated. It can be downloaded from ...

https://sourceforge.net/projects/fldigi/files/AndFlmsg/

TIVAR, a simpler receive-only, decode-only version of AndFlmsg is available here ...

https://sourceforge.net/projects/fldigi/files/AndFlmsg/TIVAR/

For decoding using Android, patch cords can be problematic, so it might be easiest just to use acoustic coupling, i.e. placing the HT next to the Android device (radio's speaker near Android's mic).

HF digital nets

In addition to receiving and decoding the modes on 2 meters and 440 MHz FM, there are some HF amateur digital nets that can be decoded using Fldigi and the Android apps. These NBEMS (Narrow Band Emergency Messaging Software) nets usually take check-ins in the Thor22 mode (78 wpm), and messages in MFSK32 (120 wpm). If your radio has a digital (dig) mode, use it. Otherwise, use USB. If you can, feel free to check in!

Nets in our region:

New York NBEMS Net
Saturday 0800 EDT
3584 kHz USB (sometime difficult to hear in Virginia during the summer)

Pennsylvania NBEMS Net
Sundays 0730 EDT
3584 kHz USB

US East NBEMS Net
Wednesdays 1900 EDT
3536 kHz USB
Check-ins in MFSK16, messages in MFSK32

Most evenings you can hear and decode similar nets and digital QSOs around 3585 kHz, plus or minus a few kilohertz.

Shortwave Radiogram

Another workout for your Fldigi software or apps would be my Shortwave Radiogram project. Digital text and images are transmitted by shortwave broadcast stations in Florida and Pennsylvania. Information is at http://swradiogram.net .

Shortwave Radiogram Schedule
(days and times EDT; frequencies in kHz):

Thursday 7:30-8:00 pm 9265 from WINB Pennsylvania
Friday 9:00-9:30 am 15770 from WRMI Florida
Friday 11:00-11:30 am 15750 DRM from WINB Pennsylvania
Friday 10:30-11:00 pm 9265 from WINB Pennsylvania
Saturday 9:30-10:00 am 15770 from WRMI Florida
Sunday 4:00-4:30 am 5850 and 7730 kHz from WRMI Florida
Sunday 7:30-8:00 pm 7780 from WRMI Florida

(Here in Arlington, because we are only 75 miles from their transmitter, WINB is usually difficult to receive.)

May 30 International Space Station pass over Arlington during school telebridge contact

Michael Callaham
 

Yesterday, April 27, Kim KD9XB sent me the text of an unattributed tweet which summarizes the info now reported in ARISS News Release No. 20-03 (which you may read--do read it--on www.ariss.org ) and also suggests that AB1OC, in New Hampshire, is the station that will provide the radio link to the space station.

As it happens, the ISS will also be "visible" from Arlington at the same time, so you may be able to hear it (details below).

ARISS News Release No. 20-03 also invites the public to watch the pass on the new ARISS YouTube Channel at

https://youtu.be/Cu8I9ose4Vo

My Gpredict software, using data (Keplerian elements) refreshed this morning, predicts the half-minute-by-half-minute azimuth and elevation of the ISS from my location:

The downlink frequency should be 145.8 MHz (plus and minus a few kHz of Doppler shift) and the mode is FM. You should be able to hear it on an HT, ideally in a high, unobstructed place or using a high, unobstructed antenna. The maximum elevation, from here, is not very high, 23.26 degrees, so obstruction can definitely be a problem, and the minimum range is not as short as it may be at AB1OC.

Hi Mike and Benn, and all other hams in Arlington,
that was me (KN4YPD). Sorry that I did not make it clear.
I was licensed last year but was not active until recently. I was
very excited to join our net for the first time even though the
connection was poor and I could only hear 30% of what you are saying
using the rubber-duck antenna.
My name is Zhe Yuan, living in Rosslyn behind that famous Pho 75 noodle place.
I had attempted several times to join our net but failed because of my
misuse of the antenna. I did research again last night and finally
figured out that there are at least two sub-types of Nagoya-771 on the
market. The one I was using was designated for UV-5R but I was using
UV-XR. The two radios look quite the same but are a little different
on the edge of the connector (UV-5R is thicker and UV-XR is thinner).
I now give out two free NA-771 designated for UV-5R for our hams.
I then purchased several antennae designated for UV-XR last night.
Hope we can communicate more on the radio=)

73,
Zhe (Eugene) Yuan, KN4YPD
