Packet Radio Node Commands (With Video)
I have been running a packet radio node for a few years now, but I am far from an expert. Actually every day, learn something I didn't know the day before. When I got started, I did quite a bit of research on packet radio, but unfortunately I had a hard time finding much. I guess it is simply too old a mode, and furthermore there were no nodes around for me to try. Now that I run a node, I think it is beneficial to get some information out there so others may get inspired to try out packet.
I am going to run through some basic commands to get you connected and exploring your local node.
First, to connect to a local packet node, you need to know a few things. First, you need to know the callsign and ssid of the local node. For example, my local node in Bay County, FL is KK4DIV-7. Next, you need to know the frequency. Again, in the case of my node, I am on 145.05 MHz. You will also need some hardware and/or software. You will need a radio and most mobile radios work very well. You can also use a handheld, but you are limited on power output. Next, you will need either a hardware TNC or a software TNC with a soundcard interface. And last, you will need a computer running some sort of terminal program. For local access to my node, I often use my Win10 laptop with Putty terminal software into my Kenwood TH-D72. I like this little handheld radio due to it's built-in TNC. It keeps things small, portable and simple.
So, what commands do you need to know for the node and what do they do? Here is a list and a brief description of the commands for my BPQ32 Packet Radio Node, KK4DIV-7.
? ... This will list the commands
BBS ... This command will allow the user access into the Bulletin Board System. With the Bulletin Board System, you can send and receive messages, read bulletins from around the world, pass NTS traffic, etc.
CHAT ... This command will allow the user access to the chat server. Often these are linked with other nodes so you can chat with people outside the local area.
RMS ... This will allow the user command line access to the winlink server. It is tricky to access, and will get it's own write-up.
SYSOP ... This will "ring" the sysops computer, open up a chat window on their computer, and allow the user to chat directly with the sysop.
CONNECT ... Will allow the user to connect to other nodes on the "nodes" list or to other stations on the "mheard" list.
BYE ... Will disconnect the user from the node
INFO ... Will display information about the node.
NODES ... Lists the other nodes that the node the user is connected to has heard and has communications with.
PORTS ... List available ports on the node such as the VHF port, HF port, etc.
ROUTES ... Lists direct routes to other nodes usually directly connected via AXIP or VHF packet.
USERS ... lists people currently connected to the node.
MHEARD ... Lists the last seen stations on any given port. For example, MHEARD 3 lists the last seen stations on port 3 (in the case of the KK4DIV-7 node, port 3 is the VHF port).
That's the list of the most common commands for users connected to a node. To see these commands in use, watch the video I put together below.
Well, until next time...take care and 73.

It's a wrap...Winter Field Day 2021
Well folks, it's been a week since Winter Field Day. Carla and I camped at Three Rivers State park in Sneads, FL. We weren't alone; several members of the Panama City Amateur Radio club were there. Greg (N4KGL) and his wife, Daniel (K4MDA) and his family, George (W4GHG) and his family, and Ryan (K1OSE) and his family all participated from the campground this year. We also had a couple hams drop by to visit, Frank (KC8VKA) and Adam (KO4KOF).
Due to the ongoing pandemic, WFD 2021 allows for members of a club to combine scores and be grouped together as a club score. This allows us to stay social distanced while still being able to participate as a club. While we all were at the campground, we did maintain social distancing guidelines.
We arrived late Friday afternoon and got camp set up. The first night was quite cool and temperatures were in the 30's F. Saturday I got the IC-705, Solar, and antenna set up. I used a Sotabeams bandhopper 20/30/40 meter antenna and a 80-10 meter endfed antenna as a backup. The solar system I have is a 120 watt Bioenno solar panel, Bioenno solar charge controller for LiFePO4 batteries, and a Bioenno 40 AH LiFePO4 battery. I really can't say enough good things about the Bioenno equipment. Everything works flawlessly. The solar/battery combo kept the IC-705, my 15" Windows 10 Laptop, GoPro camera, and our phones charged and powered for the entire weekend, with no noticable drop in capacity.
Rain rolled in early Sunday morning, but didn't last too long. In the end, I had 33 PSK31 contacts. Not a super high number, but I was QRP, and I am okay with that result.
Scoring:
33 QSOs
33 x 2 (digital) = 66 QSO points x 4 Power multiplier (QRP) x 3 Mode and Band multiplier
= 792 points
Bonus points:
1500 Outdoor station
1500 Away From Home
1500 Non-commercial power
= 4500 bonus points
Total claimed score = 5292

Until next time,

Building a 10 Meter Dipole
10 meters is one of my favorite bands. I guess it reminds me of how I got started in radio, back in my CB days. CB/11 meters is very similar to 10 meters when it comes to propagation. When it is hopping, you can hear people from all around the world. What makes it so much fun is the uncertainty of the band.
I needed an antenna for 10 meters. I looked into purchasing a vertical 10 meter antenna, but that's no fun. I enjoy making my own antennas and it is satisfying to make contacts using an antenna built with my own hands. I have made several antennas over the years. From fan dipoles to tape measure yagis to my log periodic satellite antenna, I enjoy making them. What I enjoy as much as making them is bringing all of you along with me in the journey through the project.
My latest build is a 10 meter dipole. I fashioned a center mount to attach to a mast and I use two stainless steel 102 inch CB whips for the elements. I measured the swr of the final product using my nanoVNA analyzer and was pleasantly surprised how well it performed even at the top end of the 10 meter band.
I have the antenna up in the air and am anxiously waiting for the bands to come alive in the upcoming solar cycle. I hope I do not have to wait too long...
Part 1:
Maybe this will give my viewers some ideas and get the creative juices flowing. Get out and build something.
