I had quit using my Micro PA50 because the fan was too loud. I like your solution

[philipwells]

Great call sign and good informative content.

Can you tell me if the micro pa50+ is able to run at lower power output of max 7-10 Watts. I'm looking to use it with my hermes lite 2 to drive an rm Italy amplifier which requires 7-10 Watts input at maximum. Thanks for doing these videos on the hermes etc very informative.

Thank you for the video enjoying the hobby more than anything

Thank you for this awesome informative video, I own Hermes Lite 2 SDR and I really want to add an external low cost Auto tuner and PA

Are you going to change the fan on the 50+

[michaelwurzer]

Very helpfull!
You say it was shipped with Firmware the high SWR Issue really solved in this version? (some YTubers say NO!)

[ChaplainDaveSparks]

I’m pleasantly surprised that it includes bandpass filtering. So many Chinese amps *DON’T.* It might be a good companion to my (tr)USDX.

My QRP rig has no output power control. It puts out 5W. My PA50+ goes over 50W with the 5W input. It sets off the alarm and then shuts off the amp. I did notice that the amp can run at a much lower voltage. And its output power drops. I tested with a LiPo battery that was a bit low at 11.1V. So I ordered a 9V power supply to see if I can get the power output down and the alarm off. If I can get 25W out I will be happy.

Can this amplifier be driven with less then 5 watts ? Lets say 3.5 watts ?

[eddyyantosjahputra]

07:40 That resistor that you soldered on top of the other resistor is not 68 Ohm as you mentioned. It is indeed 47 Ohm ...

Hi, got my MicroPA50+ today and when testing I noticed that on 15m (21.220) when I press PTT, the unit goes into "BYP". SWR without tuner is 1.2. Any thoughts why this is happening. Other bands, PA mode is working just fine.

[williamsteele]

Where is the best place to order your pa50+ ?

[Funkwelle]

Nice job. However a comparison of the inside of both amps would have been nice. Maybe there wer changes too in the circuit.

And please allow me a little advice: get yourself a tripod. It makes your videos less shaky and you have both hands free to show things.

if 12v 0.5w input~~~~ output? sorry i am poor at english.

Dear sir it's working with usdx 8band qrp chinese radio

[carltekcarlotech]

i hope you can make a video on the firmware update thank you.
