NAQP RTTY July 2020 – 120 contacts

I put in a part time effort (5 hours out of 10) in the North American QSO Party RTTY contest for July. I made 120 contacts, one was Hawaii. I was on Team Aardvarks-1, we had enough people to field 2 teams this time around with people from the SPARC club. Hopefully interest continues to grow. I had a lot of QSB(fading signals) in the beginning but it got better after dark. I went until 1am and then threw in the towel, it goes til 2am. Last year I got 139 contacts over 9 hours, much better rate this year.

Also made a couple contacts in far east Russia. This was a fun one, looking forward to…

NOAA weather satellite image receiver

I read an article about a QFH antenna in the May 2018 QST magazine (page 38, link for ARRL members) that could be used for receiving NOAA satellite weather imagery using an RTL-SDR dongle and a Raspberry Pi. This is a very common project with RTL-SDR dongles(which are $20~ USB radio receivers), check out RTL-SDR sub-reddit for lots of people’s results. QFH stands for QuadriFiliar Helix. It looks like this: I purchased all the parts besides the coax and PL-259 connector from home depot for around $30. At first I followed this instructable on setting up the Raspberry Pi to automatically download the images. I ran this for awhile and didn’t…
