hamlib + wsjt + gpio??? #wsjt-x #hamlib

Just wondering, I know people have gotten wsjt to work with cat control or usb control, but has anyone gotten a work around to use the gpio pins for the ptt?

the main reason I ask is that when i switch radios I don't want to try to mess with cat or usb control, and some of my rigs have neither. it would be nice to be able to switch between any radio w/o extra control cables.

I haven't played around with hamlib enough to know all its features yet, but has anyone added gpio support to it?

Re: Point to Point (P2P) email transfer #draws

So we do have two way communications working now.
  *We address each other's system directly with call sign (no SSID).
 * We always address the emails with full Winlink.org email address.
 
I will try and complete some more concise documentation on what we're doing and the configuration of the other stations.
Appreciate (again) all your help Basil.

You haven't said what the receiving end is. Since I'm assuming it's not
paclink-unix they need to follow their app requirements. paclink-unix
will receive whatever they send p2p addressed to email address
n7kjk@... and sent via your callsign no SSID.

They're not using a DRAWS . (not sure exactly what digital components
(physical and/or software) they're using.
It doesn't matter which TNC/sound card you use, paclink-unix is
independent of everything below the AX.25 socket interface.

He indicated that Packet P2P had to have the messages addressed to the call
sign - sans @winlink.org.
Whatever app he is using will have different requirements than
paclink-unix that you are using ... unless he is using paclink-unix.
I have only tested p2p with Airmail & Winlink Express.

With this information we'll run some more tests.
since I'm receiving email with the full winlink email address from him when
he calls N7KJK (no ssid) something's working.
He needs to follow the requirements for his app.

We are wondering why my messages show up on his end sometimes with SMTP
reference (see image attached).
I don't know. Expand the columns so I can see all the information.

paclink-unix is SMTP compliant and uses postfix to set the required
email headers. The email that you compose with paclink-unix will be
accepted by any other SMTP compliant email system. Try CC'ing your gmail
account when sending messages either with wl2ktelnet or wl2kax25. For
p2p it only makes sense to have a single 'To:' destination address.

This is getting very very close. It's going to be very helpful for
volunteer event coming up next weekend.
What Winlink apps are other participants going to be using?

You are using an unqualified email address. If you did this using mutt

Correct, the address you use must be a valid email address,

Send me the file you are about to send from /usr/local/var/wl2k/outbox.
Looking at that file I can tell you whether it has a chance of being
sent properly.

Exercise for you:
Compose a single message to k7rmz@... and copy it to a temporary directory.

Send it using: wl2ktelnet

Copy message from temporary directory to /usr/local/var/wl2k/outbox
Send it using: wl2kax25 -c k7rmz-10

Copy message from tmp directory to /usr/local/var/wl2k/outbox
Make sure k7kmz is set to receive via p2p.
Send it using wl2kax25 -c k7kmz

Cut & paste the console output from those 3 transactions in a regular
email to me.

I’m operating remotely at the moment, I’ll double-check everything when I get home. It’s got to be something hardware at this point but I’m out of ideas.
