We are working on full "Hardware pager" with embedded transceiver, STM32 controller and e-Ink display too...

Versions for small Linux systems probably will be made also, but some later...

i would say not use the phone area (dx window)

better stay in the digimode/cw portion of the band (lower end) ... what about 3580 and 7080 (just an idea ... did not look in bandplan) and maybe 14080 in 20m?!? (matching numbers makes remembering things easier)

Didn't think about the band plan on 80? What would be a good 80/40 Freqs for this mode?

Re: VARA on FM 2M

Andy,

you don't need a gateway to try out VARA FM. Only a buddy who is interested. Then set it up for P2P operations. 
I would argue it is a lot more fun that gateway operations, too.

Assuming that your Rigblaster is connected to your ID5100 via the RJ45 mic port?
If so, consider getting a A/B switch and plug in your mic in one port and the Rigblaster in the other.
That way you can coordinate traffic on the same frequency with the other station.
You will find that VARA FM Narrow will work nicely with this setup and deliver speeds about 8x Packet.

As a side note for others who may read this: Generally speaking rigs with 6 Pin Mini Din connectors are a better choice if you want to get serious about digital operations.
But if you want to just play around for a while make it work with what you have.  My first forays into digital were with a Baofeng, good outside antenna, Signalink and a friend.

Have fun experimenting!

Features of the PS-18 (HF pager) mode.

1. Used simple but robust modulation (18-tone IFSK).
It can be transmit and decoded easy,
but it is resistant to noice, fading (amplitude change)
and slow frequency deviation (inaccurate tuning).

2. An effective FEC is used based on the Reed-Solomon code RS(15.7) with fourfold
interleaving, which allows you to work through
channels with deep and long fading with up to 25% of raw errors.

3. The baud rate (5.86 or 1.46 Bd) is selected by the operator,
the receiver decodes both speeds simultaneously.

4. An exchange of address messages up to 252 characters long
without establishing a connection is provided.

5. In response to a received message positive (ACK) or negative (NAK) acknowledgment
can be automatically sent.

6. The message may be automatically repeated until confirmation
is received or a timeout occurs.

7. It is possible to automatically transmit periodic messages (beacons)
to identificate station presence on air. A beacon can be accompanied by
telegraphic CW-ID at a speed of 100 LPM (20 WPM).

8. The complete set of data from the GPS receiver may be included in a beacon.

9. The identifier of the terminal is a two-byte integer (1 ... 65534),
amateur callsign can be included if necessary in the message text,
beacon or in CW-D.

10.A specially formatted amateur callsign in a text of a beacon or
a message can be used to identify the operator during forwarding
a beacon or message to the APRS network.

11.The protocol itself allows you to transmit a full set of single-byte characters (0 ... 255),
the text part of the message displays an almost complete set (1 ... 255).
Android version of software displays characters as transmitted in Windows-1251 encoding.

Originally software was developed for NVIS propagation at lower frequency HF-bands.


There is R1BBG via UA3AHM-PG gate at 3.775 MHz, 40 W and 2 (two !) meters pin was used.

https://aprs.fi/#!mt=roadmap&z=7&call=a%2FUA3AHM-PG%2Ca%2FHFPG05009&timerange=3600&tail=3600


Surely, it can be used for DX communications at 20 meters and above also.

The PS-18 mode is developed for reliable exchange of real information
between live people.
It is not chat mode, not contest mode and not "just make QSO" mode.

It is really very like APRS, but is much more robust.

Re: New digital mode PS-18 (HF pager) from DXsoft and Radial, or we invented APRS again :-)

 

Hi Sergei.

I am a little confused. I use the term "chat" as the same as "conversation" as the same as "exchanging real information" between live people. Mostly a QSO where it is not (semi)automated or conducted with macros only but keyboard to keyboard typing between two hams. That sounded like PS-18. I will find and download to learn more.

In addition I have used fldigi/flwrap/flmsg as a way to exchange error corrected messages for others like when I was an NCS for a digital traffic net. In addition JS8Call allows messages with check sums to be relayed and stored or picked up. FSQCall allows the same thing and has a messages helper application. Both with live people and dropping off messages to help say remote stations communicate via relays and send messages.

So I am not sure how the above is not exchanging real information between live people same as with PS-18. Line or sentence at a time as different speeds and robustness depending on which underlying modem you are using.

I tried JS8CALL but didn't care for it. However, it is widely used... at least as much as Olivia, probably more. The problem is that the waterfall signature of JS8CALL is virtually identical to the waterfall signature of FT8, but there is no interoperability between the two modes. Having JS8CALL and FT8 share a frequency would be chaos for both modes. A proposal like that would be "dead on arrival".
