Very nice Tony. Great to see how well you're doing and that you're having a lot of fun too because that's the main thing. Your buddy Joe in Gilbert, AZ. 2AZ8255.
That’s the best part of the hobby. I never could stand when people cover up components and are afraid if someone takes pictures of the components and shares it. I will provide any value, setting voltage component and even part number of any amp I build and I welcome everyone to copy share and reproduce my work. It’s all part of the fun.
I come over after watching BBI brag in awe of Iowa impressed he was on your work. I've been trucking for basically 40 years and your design and your work is OUTSTANDING!!! I'm very interested but I also figuring I'm inn for sticker shock! wiyh that said it will be because I have no idea on the cost of components or time to build one! So if I can take that unit from my base in my home and also run it in my mobile I have no doubt it will be Wirth the cost.
You can email me for pricing. Ad I am currently trying to clear some bench space for a very large build. But best answer is think a dollar per watt. 😉 xelectro@me.com
It blocks any rf from coming out of the power rf transformer and also filters some high frequency power supply noise and it had electrolytic caps on both sides of it
Hello, thanks for such a wonderful video, it is possible to obtain from you the circuit of this magnificent amplifier, or you sell them. Thank you for your future reply. 73`s by EA7KNH
Copper heatsink was cut on a bandsaw. LDMOS from Mouser.com (MRFX1K80H) Circuit boards are my own design that I sent to jlcpcb to have printed. Everything is made by me. And tested to achieve the results. Circuit is also made by me
@@NeedleBender785 Thank you for the details. I didn't get my boards from Ebay. But I am having difficulty finding the best place (and recommended size) of copper plate to use. I am building a dual MRFX1K80H. I Have a GIANT aluminum heatsink to attach to the copper plates however. The other part I am having difficulty with determining is a power supply. Any recommendations? In Canada the Legal Limit PEP is 2500W. I am hoping this one runs right close to that.
@@rustylimbo Copper heatsink is 4”x6” (needs compound between copper and aluminum) Pill must be soldered to the copper. Power supply I recommend is 0-70v 3000w from AliExpress. Or 63v antek 1500w supply. (Does less watts because of voltage drop then the AliExpress one) always make sure you are never exceeding 65v I know it’s tempting to go higher on the volts but these things are not forgiving on volts. They can run with very bad SWR but don’t exceed current 40a, 65v and 100celcius on temp and you’ll be ok
Now I wonder how you are going to operate that in a mobile? having to come up with that many volts to operate it off of. Unless you step it up using 2.5 farad capacitor and kept stepping them up to the voltage we need for the device. Or 1800 watt DC buck converters another possibility.
Not a commercially available item, it’s something I designed and built myself. It’s only designed to operate from 10m to 12m and has a band pass filter with a center frequency of 27.4Mhz configured as a Pi network.
A Ham ! Great to see. Yes these are available as a kit. This device should run CW 1500 watts all day long with adequate cooling. Google W6PQL.. the guy has done some serious home work and plenty to offer up into the microwaves.. 73 from ZL.
When you look at the pallet, the top left side of the board. There is a 4 turn open air coil with 2 capacitors, one on each side of it. That’s a Pi network.
