Ham Radio

Some QRM...

Submitted by gpmidi on Sun, 12/19/2021 - 16:00

Just a tad bit of QRM here. I suspect it's the battery charger I'm using as a temporary power supply. Normally I have a bunch of filters between the radio and the power system too. That's also missing. Once it's reinstalled the problem should go away. I hope. Lest it's something harder to fix...

The Sterling, VA, USA repeater and WIRES-X node is now up and operational. 

It is a full duplex WIRES-X node, C4FM Repeater, and FM Repeater in FM19ha run by KG4TIH.

This Yaesu DR-2X repeater on 70cm is set for analog and C4FM mode. The node is set to auto join the VA-Sterling (28558) room after an inactivity period of 10 minutes. When in this room or others all C4FM traffic will be sent to the Wires-X room and all signals received via the room will be transmitted via C4FM. The Wires-X features on some Yaesu radios will allow the user to control what room is connected.

On Tuesday 2019-10-29 at 11:01 AM US/East a team of amateur radio operations, myself included, made contact with the International Space Station. Thirteen students from Farmwell Station Middle School (FSMS), part of Loudoun County Public Schools (LCPS), were able to ask questions of Dr. Drew Morgan. This was thanks to the Amateur Radio on the International Space Station (ARRIS) program and Loudoun Amateur Radio Group (LARG).

Ham Radio: The Old Guards vs Everyone Under 60

Submitted by gpmidi on Thu, 08/29/2019 - 17:01

For those who aren't aware, there is a bit of controversy in the ham radio community at the moment around Winlink. The tl;dr here is that a bunch of boaters started getting ham radio license so they could use Winlink to send and receive email when they're out at sea.

The problems started when a few of them started using it for more than personal use - they were using it commercially. This is strictly prohibited with ham radio. This is compounded by some of the boaters not using it properly; they'd use it on frequencies already in use by others at that time.
