I've been a bit slow updating this section, recently I have been putting together a 2 meter digipeater, that will live here at the house. It appears to have about a 40 mile radius. I will try to put pictures here as time permits.
For regular 2m/6m/440mhz, I use a Standard 5900 DA Tri band mobile.

The Yaesu website no longer has information on this radio. I looked all over the web recently and found there were no links to the manual where you download the PDF. Lucky for me I found the old PDF on my external HDD and decided to make it available here along with a simple document outlining the mode for the radio to open up the transmit and recieve.
5900da Owners Manual 5900da mod I have searched the web high and low and have found very little talk about this great radio. If you have a 5900da feel free to contact me and chat.
JUST A NOTE*** Standard was bought out in the late 1990's by Yeasu and no longer exists of itself.
Last fall I put up a Dipole (of sorts). long story. I will again post pictures as I am able, but needless to say it is still in the testing stage. It is feed with 450ohm ladder line, and has a 4:1 homebrew balun the WH2T variety. IW5EDI has the instructions on his webpage. It appears that the information presented by wh2t is no longer available on his page.
I have found this balun to work quite nicely, is easy to build and is rugged in
its durability. I guess you can't ask for much more than that right?
RGEN RECEIVER PROJECT
Recently I built a regenerative receiver circuit designed by KC8BRO Shane Feek. This Radio has frequency scaling based on the coil winding. It employees the use of a FET transistor. The tuning is very selective and the receiver it self is very sensitive. Below are pictures of the radio designed for 2-10mhz shortwave. It covers also 80 and 40 meter ham bands and WWV time stations. *** NOTE where it says FINE TUNE. I inserted a banana socket for a ground wire until such time as I build the fine tune circuit.
