Post Field Day

I ended up doing 100% WSJT-X modalities during field day due to using only 5 watts and being in a relatively isolated area.  I even was able to get some 80 meter contacts but had to boost power to do so. 
I added my Alex Loop as an alternative antenna so I could more rapidly transition between bands.  During the daytime the vertical was set to 20 meters and the loop to 40, and at night the vertical was tuned to 80 meters.

All in all a very fun experience.  My battery settup lost the ability to fire the transmitter about 6 AM, so that's when I stopped and joined my family for church. (That's a Knox Bible for those who are interested in such things- a rather good Catholic version translated by Ronald Knox).

Field Day Settup

As the last few hours before the start of field day tick away I have finished setting up the station in a remote area of my front porch, far from the grid and from civilization.  The station consists of a Raspberry Pi 3 running Raspbian, a 12v camper hdmi TV, Yaesu FT-450 transceiver, SignaLink USB interface, alpha antenna DX 10-80 meter antenna, tuner, and miscellaneous other things.  All is working great and is powered with 2 linked fully charged deep cell 12v batteries.







Hope to work you on the bands!

Pre Field Day

Hello World!
I've been busy this spring and summer with Sea-Pac 2017 and with preparations for field day, as well as reorganizing the attic ham shack, running the hobby farm, dealing with winter damage, working on the barn project, and working in the ER full time as well as family activities.  No recent satellite activities unfortunately, but I have installed my Alinco DX 70 in my car with an independent power supply that is much more quiet than my prior installation, and learned a lot of linux.

I plan to do a low power RPi centered field day this weekend.  Unfortunately I am working all the way up to this Saturday, with 12-13 hour shifts on each day/night if I get out on time (ha!).

Here is my attic ham shack, northeastern corner
Here is the view out the southern wall/ window (life is tough in such a beautiful place, eh?!)

Here is my faithful Raspberry Pi 3, running my Yaesu FT-450 on WSJT-X WSPR 20 meters at the moment.  It also does fldigi well.  Full working CAT controls.  I found out that you actually DO have to cinch down the serial connections with the screws if you expect them to work consistently.  Go figure.

Hope to work you on field day!
