Mr. Carlson Makes a Thermatron Power Supply for a BC-348

When I was 14, I had to make a power supply for a Heath HW-32A.   Mine ended up working, but it was nowhere near as nice as Mr. Carlson's BC-348 supply (shown in the video above).  I didn't have a sand blaster, nor a drill press, nor much of anything else, really.  

But hey, don't real boatanchor hams use Greenlee chassis punches?  What's with the drill press and the hole saws? 

Note that Mr. C takes care to make sure that the rectifier tube is in the proper angle FOR OPTIMAL VIEWING.  That's some serious attention to detail OM.  And whoa, DELICATE SURFACE MASKING TAPE from 3M?  Respect!  Also, era-specific looming material. 

His point about the importance of the cardboard washers in the power transformer was really useful.  I hadn't thought about that. 

Here are the two previous BC-348 videos: 



Thanks Paul! 

RAC Canada Day Contest-report

Well the RAC Canada Day Contest is over for another year.

As with all the RAC Contests I set certain goals for my self and for this one was no different.

The goals were as follows:

HAVE FUN- This is a must. I am a casual operator and not a “dyed in the wool” contester. The main thing is to have fun and keep it friendly… This was not an issue and I had a blast working across Canada.

TRY AND WORK CANADA COAST TO COAST TO COAST-

Well almost… I had contacts in:VE1, VE2, VE3, VE4, VE5, VE6, VE7, VE8, VE9 and VO1. East Coast to the West Coast and the North West Territory.

Unfortunately this time VO2,VY0, VY1 and VY2 escaped me.

HAVE A SCORE IN THE TOP 50% OF MY CATAGORY. Needless to say that this time its not going to happen. I made contacts on 15m, 20m and 40m and they were good contacts…. I just needed more of them.

After about 9 hours of radio stretching it out over a 24 hour period it was all over. One of the lowest scores I will not be submitting but it was still fun.

Onwards and upwards so…. Happy 4th of July to my American Friends…. I’ve already gotten 7 of the 13 Colonies station in the log and I started chasing them today.

Check out their website for more information.

Then it looks like its back to “Playing Pota” again ….

The Coles Notes Version:

Operated for approximately 12 hours….

81 SSB contacts…. on 4 amateur bands

54 contacts on 40m, 16 contacts on 15m, 10 contacts on 20m and 1 contact on 80m.

Furthest contact was with KL7SB in Alaska, with the next furthest being K6JO in Orange County (LA) California.

Made numerous contacts up and down the Eastern Seaboard.

My Yaesu FT991a worked flawlessly and the antennas I used was my 60 ft (approx) inverted L for 40 and 80m.

My homebrewed modified Coastal 20 antenna was excellent on 15m and 20m.

This was a great “Warm up” for the RAC Canada Day Contest coming up on July 1st

Thanks for the contacts…
