If you read previous posts, you know this past weekend I took part in my first ham radio contest. It was the North American QSO Party. I was also trying to take part in the ARRL VHF January contest but that was fruitless, completely. Saturday afternoon about 12pm CST I started my setup. I gathered up my antenna supplies, a 20 meter home made wire dipole with a DX Engineering Alpha Delta Antenna kit. Basically it’s just a feed point and two insulators. This was going up into two tree’s outside the radio room’s window, so I also used rubber bands to lash the various pieces in place. Then I just opened the windows a smudge and feed in the coaxial feed line it’s self. This all worked really well!
By this point it’s about 12:40pm on Saturday, 20 minutes to go. I now grab my laptop put it on the desk, turn on the PS and finally radio. I’m using the NAQP program by N3FJP as my logging software. It’s simple, easy-to-use and this program is specifically made for this contest. N3FJP has a whole suite of programs for popular various contests. I had tried to get my radio to interface with Ham Radio Deluxe, but it just wasn’t having it. O well.
It’s now 15 till start time. Everything is on and charged. I tune up the antenna just to tighten everything up. Since I had extra time I tuned around and called CQ for about 13 minutes and 6 contacts so I was feeling pretty good about it. First hour 20 contacts right out of the gate. All over the north, north east, south and south eastern side of the USA and I think one Canada contact. So I take a lunch break and sit with the wife for a few and then get back at it. 26 more contacts in about an hour and a half.
This is awesome, I mean I don’t have a pile up of people looking to talk to me when I’m working CQ, but every single station that I come to that’s calling CQ I get through to. Including a pile up or two that I make it through. Remember home made antenna in a tree that’s not near as high as it should have been. I’m having a ball!
At this point I’m 4 hours into the contest, I’ve stepped away to do something for the wife. I come back and turn the radio back on and my for whatever reason my power supply takes a dump. The fan inside revs up to full speed, as does the voltage read out. It maxs! As quickly as I can I turn it off and unplug my radio from it. I put a voltmeter on the PS and 31.6 volts. AGH! So pissed.
Power Supply is a MFJ-4245MV
My nice, beautiful, expensive, new Yaesu FT-950 was over volted! Then I’m taking another reading and the POS power supply shocks me. I’m touch the metal chassis of the case and the negative terminal. I then, after my arm stops hurting, take a measurement on the chassis. 186.9 volts. At this point I go, pull out my antenna and bring it in. My contest day is over. Tomorrow, tuesday 23rd, I’m calling MFJ.
I’ve always heard the MFJ isn’t the best but I really was trying to buy from an American company. Astron
