Id like to see a home brew thread (tacked maybe?) with projects and ideas. That is a big part of ham radio I think. Could be a place where people could post questions about something they want to build. Just a thought. |
SGC Smartlock and Rig switch. On the left side, needed to have a smart lock for the Kenwood radio, and have a tuner interface for the icom 706, so I needed a way to incorporate the smartlock and a switch to change between the rigs.
ETA: To think about it most of my stuff is home brew, I enjoy the satisfaction of building something and using it. If anyone needs larger schematics let me know. |

AM radio I built a few years ago. It works ok. Either way I built it

Here is a couple of links to some CI-V cables for Icom radios for doing digital. This is one I made a while back:  Another page with a few different versions: They arent hard to build if I can do it. I think KB7DX turned me onto this design. ETA: Im looking for some HF antenna designs if anyone has anything. |

My dad and I used to build a lot of home brew tranceivers, amps, antennas, computers (pre IBM era). Now I don't have time nor patience. He still builds a lot if stuff although he admits that he can no longer compete with high end digital rigs.
Here are a few pics of his latest built: Home brew HF amp based on a single 4CX800 (GU-74B) ceramic tube. Unlike other commercial amps this one is whisper quet. The tube cooling fan hardly makes any noticeable noise and can be easily removed from the back of the amp enclosure for easy transport. He built it from scratch, including the enclosure and the transformer. Looks professional, doesn't it? It may come home with me one day.

how about a simple question?
I have an UPS that outputs 12V and has a 120V AC input to charge the battery. Can I simply cut the AC line and terminate each side with a quick connector of some type? (leaving a stub on the UPS side, say 6in?) I was thinking of terminating the UPS side with the male end that would input to this type of AC cable: 
The UPS is small enough to fit in something like a motorcycle saddlebag. |

Ok I found the cable on stayonline.com (how is that site?) as well as some panle mount male, C8 as I found out they are called. If I'm just cutting cable without disturbing the connector how would you recommend I reconnect? Crimp connectors? Is there a particular one? Shrink wrap I suppose too. It is intended to be a permanent mod to the cable since I'll be keeping the typical NEMA stuff on each end. |

Coldest night of winter so far this year!
I need to add some heat to the shack! I see building 2 maybe 3 new amplifier projects. 2M and 23cm possibly 70cm if I come up with a design. Matching Triplets! Amplifer projects

How about a CRACKPOT thread?
When I key the mike it opens a relay that releases a bowling ball that rolls down the gutter that is tuned to my antenna tuner on 14.277 Mhz that releases the salt and fills the gutters to melt the snow. When I key the mike an hour later on 7.178.5 Mhz the end of the gutter lifts and the ball rolls back to where it came from and whle doing so it cracks all the ice in my gutters and keeps the ice dams from building up and also allows me to continue using the gutter as an antenna so I can work DX and yak with some guy who is two miles below the earth working in a diamaond mine in South Africa........

If you ran enough power you could use RF heating to keep the ice melted.

This is not as fancy as what you guys have built. After shelling out the $$ for a Heil microphone, I didn't have enough to get one of their swing arm booms. So, I made my own. I had an old swing arm lamp given me by another HAM. I took the lamp off and removed the power cord. I started by drilling a hole in my bench top. Then, I inserted the bottom pivot into the hole.
Where the lamp used to be, I created two extension arms out of flat aluminum stock. I bolted the microphone clip between them. Like the rest of the boom, this allows articulation and movement. 
It may not be as fancy as the one Heil sells for $120; but, it does what its supposed to. The best part of all is it was basically free. Here is an overview of the whole thing.

I like it. Boom mics allow extra desktop space and are great convenience item.
