Hi,
Can you share the Darlington Transistor Amplifier Keying circuit design that you used between the IC705 and your 40W amplifier?

Hi Glen,
I updated the blog page with the buffer schematic.

I have been listening for a while now. I'm not a very techie person. There is a lot of your content that is above my head, but every now and then something clicks and makes sense. I really appreciate the episode about antennas- it made so much sense to me and provided some great insight. I know it's entry level stuff for you brainiacs, but there are those of us who really appreciate some basic things now and again. Thanks again-

I dont have 3 hours of lawn to mow or snow to shovel.. but The informative and humorous conversation made my afternoon (and next morning) of hanging (wireless) access points at work seem to go by easier.. love that you present the turn key solutions as well as encourage people to get out there and make stuff..
