GUMBO A heavy thick stew consisting of components representative of a host of cultures and usually associated with the home state of Speaker Mike Johnson. The components can vary and some seem arcane.
I have hard data that the blog must contain a photo or video to get over 100 views and photos like yesterday's get way and I mean way over 100 views. So no risqué photos today so maybe only 50 views. But it is my blog.
The above data sheet is for a 5763 Vacuum Tube which used to be a staple for many 1950's/60's low power CW transmitters. With a good design you could get 10 watts into the wire on 40M.
I mention this tube because it is one of those hidden gems. About a year ago I picked up four of these NIB for $10 on eBay. Now that I have a spare HV DC power supply floating around which was noisy in a receiver but does not have that problem on transmit, the temptation is to draw those two together. There are many simple designs you can find on the internet or through the use of AI.
(Yeah, I know too lazy to look so click on the link)
Speaking of AI, always verify the result as often it is wrong. Here is a problem for you. You have a T-68-2 iron powder toroid that has 14 turns of #16. What is its inductance. You can use the calculator in the Kits and Parts website (W8DIZ Toroid King) Then ask at least two AI sites. Compare notes.
Well, yesterday I calibrated my Hybrid Wireless using my Hermes Lite 2.0 as a measurement device and the difference is less than 10Hz. So, let's see how many comments about being high or low I get.
Yesterday I added the S meter sensing circuitry and installed the linear amp switching. Using the Hybrid wireless as a driver, my SB200 spits out 300 watts. (About a 11.7 dB gain) I know it's not full legal limit but a lot better than 20 or 5 watts. I easily worked into the Midwest last night with good signal reports.
I have been noodling an AGC circuit for the new rig and I think I have something that will work. The bigger problem is getting access to the circuitry to make the installation.
That's All Folks and so I leave you with... Them that know can make it go!
