Imma go ahead and tell everyone right now...When this man opens his mouth...Gold Knowledge leaves everytime. Im blessed to even know him and I am grateful for every single video that he does. He doesn't have to take time to make these videos for us but he does cause he loves the hobby and enjoys teaching others. GETTING caught up on your videos over here buddy lol :) Gatekeeper
What's the best way to go from a 25-ohm output from a combiner which is combining two 50 sources to one 25-ohm output to match into a 50-ohm load and be broad-banded?
How do you design a Pie matching network , can i use a pie network immidietly after a IRF power amplifier to a 50 Ohm cable and antenna without connecting a Lowpass filter, will the pie network work alone suppress harmonics and other undesired signals other than the desired signal by itself without out a LP Filter b4 the pie network ????
Hi Rf Man! I have a Mini-Ball TL60 with one MRF453 transistor. Looking at the input with my Nano VNA it seems to resonate at 28.500 MHz with an SWR of 2.82. However with 1 watt dead key going in the SWR is 3.1 to 1 and output is 50 watts. I'd like to tune it to 27.205 and lower the SWR. Its a fairly simple amp with a keying circuit and an on and off switch to bypass the amp. Can you give me some suggestions to fix it? Thanks for your very helpful videos.

I see the old windows start button... You still u shaving Windows XP machine or probably older?
Great video! Thank you for sharing. I am re-learning a lot of stuff from you.
p.s. Audio is fine on my end.
I am happy you are enjoying my videos!
Thank you .
I use the same site
I like this site, it shows the schematics....
