My Week in Radio
- Built an Allstar node from a PI 4 and a USB-C radio dongle to reach 985
- Stumbled into and recognized some Olivia-8/250 on 20M
- Lots of ISS repeater traffic at convenient times on my good ol’ 1/4 wave antenna in the tree
- Got the radio blog up-to-date with all my adventures
- Listened to Jim, AF3Z, talk about sideswiper keys, and I might give it a try as i’ve changed the way I’ve been using my iambic paddle to almost never squeeze.
- looking forward to FT Challege
Questions
- KC3WWC, John:
I have the basic Allstar node configured.
Should I leave it connected to 985 all the time?
I recognize some of the repeater features,
so what other cool things should I have this node do?
- W3CRW, CR:
- using it for a few years
- not always connected
- switch to other nodes
- always disconnect from one node before connecting to another to avoid linking.
- has a node in 2 vehicles to supplement the reception.
- WA3VEE, Ron:
- best thing for 985
- not connected all the time
- uses HTs anywhere in the house
- operated at long distances
- be careful to not cross-link
- in vermont, connected to 53085, simplex 446.100, unknowingly connected the repeater to the entire vermont network
- W3DIB, Greg:
- Joe is adamant about avoiding crosslinks to other repeaters.
- other danger: if you are always connected,
someone else could link to you and cross-link.
- prevent other nodes from linking to me.
- disallow every other nodes
- computer security:
- keep the node up-to-date and secured.
- it used to be ancient versions of debian and asterisk
- now it’s much better….allstar 3
- careful about forwarding ports to it.
- uses a VM, flipperphone. will try to get a tutorial together.
- W3CRW, CR:
- supermon on the node allows cool monitoring with web access
- On Tuesday’s at 20:00, there is a tech net on the East Coast Reflector. The net usually runs a couple of hours. You can connect, to the Reflector via Allstar on 27339, 45225 or 45192.

- KC3RFG, Jim:
When you setup a station and all the gadgets in the RF chain,
where does a wattmeter prefer to be?
- NA3CW, Chuck:
- it should be between transmitter and tuner, so you can tell when the tuner is right
- sounds like bad cable or other installation problems?
- RF getting back through the chain?
- KC3RFG will check that jumpers are good
- NA3CW, Chuck:
- W3DIB, Greg:
On RF now, impressions of the NanoVNA?
- W3QP, Tim:
- 100% worth the money
- depends on use-case
- needs calibration all the time
- can be fragile
- great for building ununs, etc.
- dedicated VNA can be much more convenient
- uses nano vna saver python script to capture everything
- KC3WWC, John:
- so much cool stuff to measure, so opens up a whole world
- lots of more features to learn on youtube every week
- as a technical person, you’ll have a lot of fun.
- KC3NZT, Harvey:
- lots more data than a regular analyzer
- maybe doesn’t need recalibrated all the time.
- use saved calibrations
- KC3RFG, Jim:
- calibrated for each band, saved it, and recalls them.
- does lots more connected to the computer
- W3QP, Tim:
