If you are into digital and are having problems with your radio-PC interface, I found this link (in the 29 Apr ARRL Letter) to a presentation that might have the answer:

The regular VHF net was not held due to technical problems with the repeater network. The GBARC net started on HF and lasted 2 rounds.

April 27th is the annual "Morse Code Day" celebrating the birth of Samuel Finely Breese Morse, the inventor who developed the electric telegraph(1832 -35). In 1838 he and his friend Alfred Vail developed Morse Code which is used to this day. 
Morse code has been in practice for over [b]180 years[/b]—longer than any other electrical coding system. The language has found its way into Military, Aviation, Amateur Radio, and can even be transmitted by flashing lights. Additional significant use of this communication is to help those with disabilities be able to interact through simple tapping, or even through a skin buzzer.

Amateur Radio operators use it to this day, so get on the air and carry on the CW form of communication.

I came across this video and thought it would be fun to share it. There are a lot of tiny radio kits on the market for those who are keen on going very light and very portable, but this one takes the cake. This really is a full on DIY project without exception. I will not be building one of these, but if this kind of thing floats your boat the video should be inspiring. One way or another this is just fun.

I found a good website full of short tutorials on a wide variety of electronics and communications topics.  It's by Ian Poole G3YWX, a prolific author of electronics books.  Good educational reading material to browse while were "staying home".  Just as an example, I think his articles on propagation give a nice working-level overview without getting too deep into the physics. 

There's also a shopping page which just links to Amazon.

The software Packet-Radio TNC  http://uz7.ho.ua/packetradio.htm

http://uz7.ho.ua/modem_beta/user_guide_v105_EN.pdf

Years ago, it was fun to tinker with packet radio, I liked 300 baud on 80m, I had many qso's keyboard to keyboard, and the great thing about AX.25 is forward error correction or FEC. This means that what you send is retried till the checksum matches and your message is correct and complete. Gene VE3IJD had a packet BBS at his qth in Keady, we were on 2 meters so 1200 baud was used, and the system had a 9600 baud UHF link to Barrie VE3LSR via Bon VY2NX's place in Woodford. It brings back some fond memories.

At the time I had a Kantronics KAM dual port TNC which means I could use an HF rig and an VHF rig at the same time... it could even digipeat from one band to the other and it had a built in mailbox so others could leave messages. 144.390 simplex on vhf.

Well another Ontario QSO Party is over. Conditions were not the greatest throughout the day but picked up towards the evening. Nothing heard on 15 and 10 and 20 was not the greatest either. Worked Paul VE3PQ on 80 Saturday evening and that was all of GBARC I came across.
Let's hope Field Day will improve although we'll still probably be operating on our own. 
Attached is my final count.

Here is a link I came across on another forum. I don't know if FCC is concerned what goes on on the 27Mhz band but it seems not.
Check it out. https://youtube.com/watch?v=keN3K1TEvzM&feature=share 
I didn't think anyone would even consider building anything like that but I was wrong, there are more videos similar.
So where does FCC stand on that? Is 27 Mhz band self policing or do what you want on there?
