I always like your videos. I'd love to make/purchase an LDMOS Amplifier of about 800W or so from you for 10-15-20-40M mobile, but I assume they only run on 50V and can not be made to run on 12V. Running 4 batteries in series would be a bit much. So I'd be stuck with bipolar transistors?
@@rfmanchannel6915 No, he means please SHOW the output after the LPF. No LPF == not a sine wave measured by the Bird == hopelessly inaccurate. It is of no use at all showing "Bird Watts" if the meter is not presented with a pure sine wave!
I have a -6dB attenuator installed on the input side, so you can drive it with 10 to 20 watts deadkey (RMS). 20 watts for full 1500 watts of output power. The peak watts when modulating can be as high as 60 watts PEP or swing.
perhaps you could show a demo of it in say 75 mtrs or even 40 mtrs? All you have demonstrated so far is an amp for CB radio use... How about something to show us how clean it will be as you enter actual Ham Radio freq's, as the only test you show so far is not where most of us that would spend money to buy a homebrew amp...
Hello huge fan of class AB1 amps . One of my best buds told me to stay AB class for life. Best sound . You sound clear let the amp do the talking . Am confused with the myriad of radios. Guessing have a Cobra 29 for AM . Maybe an RCI 2970 for SSB ? I dunno know . Help ?
"Real" AM is plate modulated. Linear is not a greatest for AM. That's why a real 500 watt AM transmitter like a Gates or Collins takes a forklift not a brief case to move.

Low Pass Filters where are they?
I can add a LPF for an additional charge.
Mud Duck Sharky has a nice low pass filter design. Simple and easy enough to duplicate.

Nice build!
Do you have a power supply 12vdc- 56vdc to run this as a mobile
How much Drive are you putting into it bird Watts and peak watts ..... Interested

10 meters is not a CB band. I will try to make additional video in the upcoming weeks. Regards
No low pass filters, no swr protection, shitty metering. CBers love um.
How would you make a swr protector? Never heard of this.
Nice numbers and build.
NICE
Just want to make sure. Does the price include the power supply?
Yeah what he said 1,699 $ plus the ride is a lot of coin Sir.
@@unclequack5445 Thanks.
@@unclequack5445 you can always build it yourself and save a few hundred bucks.

Test in 27mhz / 7.100mhz
Yes it works across the entire HF band including 27MHz. Power output is the same....
