    11 meter is very quiet?

    Sitting in the parking lot at work during my lunch break, I managed to make contact with a guy in Cincinnati Ohio. Surprised the heck out of me when he came back to me, the conditions were a garbled mess with at least two or more people talking at the same time. Just what I needed, today is...

    The LT 616

    Yes, sideband would help it sell more units for sure. Crappy mic, but the cord is a good replacement on a real mic. Presumably it can take an electret mic?

    Bias design, amplifier design, filtering etc.

    The bias board sounds interesting, is it one board for each transistor pair?

    Bias design, amplifier design, filtering etc.

    With recent threads talking about regulated bias, I just happened to find this. Bump.

    Carlbuilt 400HD vs C400 vs CM400

    I run a Carl Built 400HD with my Icom 718. The 718 is turned down to 60 watts with rack gear going into the data port in the back. I have a hand switch that keys the radio and amplifier with a couple of relays mounted under the desk. The remote switch turns the amplifier on and off without...

    What electronics have YOU fixed lately?

    Not electronics, and I wasn't doing the fixing. I got to drink the beer and supervise. All my kids know how to work on their their own stuff...

    What is the Range of a HAND HELD CB?

    Unfortunately the antenna on a hand held CB is about equivalent to a dummy load. We used GMRS radios to communicate from house to house when we were taking care of my in-laws who lived about 100 yards up the street. We could normally talk from inside the houses with no problem. I bought a...

    You just never know what lurks below ground (plumbing)

    We had to rent a gas powered concrete saw and was able to cut and move the slabs in half a day. Once the cuts were made, we were able to lever the slabs up enough to get a chain under them. Then drug them out of the way with the golf cart.

    You just never know what lurks below ground (plumbing)

    Surprises like this always happen at the wrong time, it seems. This reminds me of some fun we had a while back. We had this situation a couple of years ago at my mother in laws house here in Delaware. We could hear running water, and could see water coming through the wall in the crawl space...

    Question requiring collective help???

    You could hoist the A99 up a tree, and just leave it hanging from the rope. Or you could mount it on the ground to make the signal go up at a high angle. I have read about people using old surplus 75ohm cable TV coax to run up the side of a hill. Spliced together with wire nuts, but the gain...
