JS8 QSO Party

Saturday, 13 April 2019

All Amateur bands, HF, VHF, & UHF


The JS8 QSO Party is a chance to get on the air with JS8 and make some contacts every month. Whether you like a quick exchange or a long rag-chew, this event is for you. We have a lot of great, patient operators in the group, so the environment should be very welcoming!

The event will be held monthly on the Second Saturday of the month (unless the schedule is modified for a particular event). Each month will have a theme or goal. 

April 2019: Hey Ponzi! Get On The Air!

The April JS8 QSO Party happens shortly after the 1.0 release of JS8. Let’s use this as an opportunity to help other operators get on the air with JS8!

Q: What does this mean? Are there points involved?
A: For every QSO you make during the event, you get 1 point. For every QSO made by a station you recruited to get on the air with JS8, they get 2 points and you get 2 points.

Q: What is the exchange?
A: SNR, QTH, Your name and the Callsign of the operator who recruited you to JS8 (if any).

Q: Since there are points involved, is this a contest? 
A: No. The rules are made up and the points don’t matter. This is solely a fun opportunity to get on the air and make a bunch of contacts using JS8. 

Remember, JS8 QSO Party events are not contests, so all amateur bands are open for use. Now might be the time to break out your 30m delta loop or 17m hamstick or 12m bed springs!

Sticking to the theme is nice, but remember that with JS8 we have the freedom of free-text. So, feel free to QSY toward a clear frequency and talk about anything you want.
