No, no need for a good old glass thermometer, or even a digital one that you would slide into the USB port. It is a simple command that you would issue from the LXTerminal or from any SSH connection where you’re doing command line.
This will bring back the system temperature in Celsius and if you want to know what it is in Fahrenheit you’ll have to do some basic conversion math:
(F-32) x 5/9 = C (remember this from school?)

It’s coming on the time of year again when the Edmund Fitzgerald is remembered by special event stations along the shores of the Great Lakes. This event is one that I always try to remember (but often don’t, sadly). The Wreck is something I remember hearing about as a child in the Cleveland OH area.
This years Stations are as follows (clipped from ARRL special events list).

This weekend is the CQWW RTTY contest, and I’ll be all set and ready to play radio for sure. I’m hoping to pick up some new DX as well as a few US contacts I still need on RTTY to finish up my WAS. The states I need are: Delaware, Rhode Island, Nevada and West Virginia. I’ll be either using my MA5VA during the day or my G5RV-Jr during the evenings. Best band I’ll be able to get down to will be 40 that way, so most of the time I’ll be on 20 or 15. Power out will be 100 watts from the 857 so I’m hoping to get a few of these put in the bag.
Today was the start of the September ARRL VHF contest. I set up happily at a local state park (Cherry Creek State Park) still in DM79 and only a few miles up the road from my QTH. After the last few days of having bad weather I figured I would get out and enjoy the sunshine. As you can see by the pictures below, it was a great looking day with a great view.
Around 3pm Mountain (21:00 UTC) the clouds decided to roll in and I could hear thunder in the distance. I quickly put the antenna and gear into the Jeep. After watching the storm in the distance I decided to exit the park. I didn’t make it before the storm hit, and then came the hail with the rain. I parked near the entrance and even tried to use a pine tree to cover the windshield to cut down the amount of hail hitting it. That caused it to build up as you can see in the two pictures. The area got swamped out where I was and hail built up pretty good. I got some video as well but that still needs editing.
I still managed to get about 18 contacts in using the FT-817 on 5 watts into my square halo 6m and 2m antennas. It was a fun day overall.
After tinkering at it for a while, I finally got JT65 working. Turns out, as I suspected, it must have been my Rigblaster PnP that finally gave up. It will control the rig but won’t get a good signal out is my suspicion. I had picked up a Rigblaster Plus off of eBay a while back and finally got it hooked up, and viola! instantly working again on digital modes. I do own a second PnP but it’s on loan to a local ham so I may have to ask for it back for my travel bag.
But back to this topic, I have managed to get a few contacts now using JT65-HF. I’m using my FT-817ND to my G5jr up in the attic. So my max out of the rig is 5w, and while I’ve seen some folks using up to 25w I’m happy here. I’ve worked mostly US stations so far, a few Canadian, but nothing outside of our “general” area. I’ve seen a few DX, and hope to get some of those but I may need to alter my antenna situation. The G5jr is kind of sloppily set up in the attic, the attic is not quite wide enough or long enough for the wires to sit straight out. I’d hate to see my actual radiate lobes. I’m thinking of putting the VA5MA up there on an angle to see if that will work any better. I probably should also get an antenna tuner for the 817.
My thoughts then come to workflow, I wandered into EQSL for the first time in a while, and found that there were acknowledgements already from some of my JT65 contacts in the last 24 hours (heck last 8). I will need to investigate what extra softwares are being used for logging and alerting that they are using to track contacts. I’ve resorted to a text file on the screen to make sure I don’t contact someone twice.
The CQ VHF contest was a couple weekends ago. I set up over on the top of Mt Genessee sticking within DM79. I managed to get 33 contacts and a couple of those were double skips out to FN12. Overall I spent about 3 hours getting the contacts before being chased off the mountain (8000+ ft elevation) by some storms moving in. I did give out 4 SOTA (Summits on the air) contacts as well.
This weekend is the ARRL UHF contest. I have to go to St Louis on a business trip so I was thinking, heck why not go Rover on Sunday and see what I can do for a couple hours. I’ll be in DM79 and DM78 on Saturday, and not sure how far out I can get on Sunday. I’ll be only running 440 USB at QRP levels into my Arrow (7 element). I’ll have my APRS running at N0HIO-7 for the trip.
Having just recently purchased a Raspberry Pi at my local MicroCenter, I’ve got to learn how to use it. Being this is my first Linux box (typically a simple Mac guy for the last few years). I figure, while I’m learning how to use it I could do a series of articles / tutorials on what I learn. How to assemble it, what we can do with it for Ham Radio, etc.
My adventure begins with first buying the parts to make a Pi work.
This turned out to be a rather simple collection of parts, I’ll list the prices I paid and if it was a sale.
Raspberry Pi Model B $39.99
iessentials USB Wall Charger (power supply) $6.99
Netis Wireless N Nano USB Adapter WF2120 $14.99
Kingston 8GB Class 4 SD $6.99
QVS Mini Fan (USB) $7.99
QVS 13 port powered USB hub $14.99 (Sale)
Coke 16.9 oz $1.29
Grand total for parts: $91.94 before tax (not including the Coke)
I already had a keyboard and mouse (USB on both) and a HDMI to DVI cable to plug this into a monitor. You can also use HDMI to HDMI or HDMI to VGA or even go good old fashioned composite video. The powered USB hub is due to the low power that the Pi requires to begin with, the Wall Charger supplies only 1a to the Pi (I went with the 5v 1a version with mini/micro-usb connector). As a result the Pi just can’t handle anything on the USB connections that require any sort of “umph”, so just get the powered USB to start with, some even can power the Pi thru the connection (went separate power supply to make sure, over kill maybe but safe than sorry).
Next post will go into the set up of the parts and getting the SD configured for the Pi, and turning it on for the first time.
