Ok the correct step is: 1-put on. No power in the input 2- bias 1 amp 3- rise soft the power max 1w But if you install a 10 db attenuator have to be better to drive the excitation 4- the temperature rise very fast. You need help the heatsink with fan’s or cooler circulation When you are close to 1kw have to be 20amp aprox in the 50v supply If you read more take care Usually you need 1/2 watts to reach 800 w How transistor you us? MRFX. or BLF ??

These guys are rookies learn how to ride

OH MY DOG! I'm so sorry, John. I think you need a higher pitched voice, OM.

Great setup. I do something similar. I scan all mine and upload to my Google drive. Access them from anywhere

Very nicely done. Guess I better ramp up my QSL collection.

How are you sharing the antenna? Where is the rsp connected? Also, can you transmit? Or is this just for listening?

I used to ride like that but with age comes wisdom. Now I just enjoy the scenery and good food company at the pit stops.

Surah Mulk indexed with number 67, number of verses 30 1 Exalted is He, in Whose hand is all dominion, and He has power over all things. 2 He it is Who created death and life, that He might try which of you is best in conduct. He is the Mighty, the Forgiving. 3 He it is Who created the seven heavens in pairs. In the creation of the Merciful you can not see any contrast, so direct your gaze to see if you see any cracks? 4 Then, from time to time, direct your gaze, and your gaze will return to you humbled and helpless. 5 We have adorned the nearest heaven with candles, and We have made them shooters against the devils, to whom We have prepared a painful doom. 6 Hell is the punishment for those who disbelieve in their Lord; what a miserable place he is! 7 When they are thrown into it, they will hear his roar and it will boil. 8 "Out of anger, he is almost torn to pieces. Every time a crowd is thrown at him, the guard asks:" Did not a prophet (warner) come to you? 9 They say: "Yes, a messenger came to us, but we rejected him, and we said, 'Allah did not reveal anything, and you are nothing but a great loss.' 10 And they say, If we had heard and understood, we would not have been among the dwellers of the Fire. 11 So they confess their sins; the dwellers of the Fire are far from mercy. 12 Those who fear their Lord without seeing it, for them is forgiveness and a great reward. 13 But hide yourselves, or speak your word openly; surely He knows what you conceal in your hearts. 14 Do not He Who created create, when He knows that He penetrates the depths of the secrets, He knows the details? 15 He it is Who has made the earth suitable for you, so walk through its parts and enjoy His bounty, for to Him is the future. 16 Have you been assured by Him Who is in the heavens that the earth may not shake you when it shakes? 17 Were you assured of Him Who is in heaven, that He should not send upon you a tempest of stones? Well, you will understand what My punishment is! 18 Even those before them denied, but what was My punishment? 19 Have they not seen the birds above him with open arms, and when the wings are folded, no one holds them in the air except the Almighty. He is the One who sees and knows every thing. 20 Who is your army that can help you but the Merciful? It is true that the disbelievers are found in a great deception. 21 Who is he that feedeth you, if He should withhold His provision from you? Nay, but they persist in arrogance and aversion. 22 Is he who walks with his face to the ground more guided, or he who walks upright on the straight path? 23 Say: He it is Who created you, and endowed you with hearing and sight and understanding, but you give thanks a little. 24 Say: "It is He Who created you and multiplied you in the earth, and to Him you will be gathered." 25 And they say: When will this promise be fulfilled, if ye are truthful? 26 Say: "Only Allah knows, and I am only a warner to you." 27 "When they see it (Hell) approaching, the faces of those who disbelieve will be disfigured, and it will be said to them, 'This is what you used to seek.' 28 Say: Tell me, if Allah takes my soul and those with me, or has mercy on us, who will protect the disbelievers from a painful doom? 29 Say: He is the Most Merciful, to whom We have put our trust, and in Him we put our trust, and you will know who the lost one is. 30 Say: "Tell me, if your water is lost in the depths, who will bring you above ground (spring) water?" ..

Talk about a pencil dive

Cased it

That guy that almost endo’d is lucky it wasn’t worse. Scary wreck! Do they have flaggers at the driveways? How do the homeowners come and go during a race?

Now thats what I call banging the ditch.

Thought I saw a current spike at 2:06 , not sure 🤔

Bish Bosh, problem solved!!

HI - Whjat Mode are using on the drive ?

Standing right there and missed the action. Lol

Looks like me when I was 10yrs old except I didn’t biff on driveways

It is on your KZbin channel.

hello, I notice that current consuption is too high for 600W with drive of 0.5W. Seems your transistor was fake, had too much gain too, or had some strange oscillations. After transistor fale, I notice also that he still drawing over 20A of current with 0.5w of drive. Thats really strange.

Now if there was a way to add some buttons right next to LoTW upload button on the logbook bar - like eQSL and QRZ........

Yeah... This is fucking bullshit and dumbassery to the fullest in my book. I've ridden for about 20 years now. Have done the iron dog ( sadly about 100 short of finish ) and this is something you just don't do even in those types of races... This in Alaska is what would he you shot out in the woods... And yes I have been shot at for basic local riding ( trying ) to take it easy over drive ways. There is so much more going on in this video than most would notice. Driveway on the right side. Seems the state has talked with them before cause of the easement passage right-a-way. I'm not saying it's not an awesome video or experience but don't be fucking up others property and just ride safe.... In my opinion. None of these riders was safe at all.

One dude came in a little hot trying to clear the driveway

Hello! Picked you up this evening via the KFS SDR in Half Moon Bay, CA. I'm an SWLer . My QTH is in southern WV, US Grid EM97bo. Rx @ 16:47 EDT / 21:47 UTC on Sat. 11/09/2019 - Callsign: NI0K / QRZ: John A. S.. @ QTH: MN. USA. Rec on 20 mtrs / Freq: 14247.00 USB / JIDX Contest. Attempting contacts with Japanese amateur operators I believe. Reception via the KFS SDR in Half Moon Bay, CA USA. Had an excellent audio reception on your station. Good luck with your future DXing. 73's de WA8097SWL / EJ Steele

Jim do you find that most ldmos amplifiers need LPF ? Eric in VT

Looks like that would hurt but on snow is not as bad as dirt or asphalt ..

please be gentle on your gates!

John- just wondering if you figured out how the gate was damaged, might have been a spike from the K3 even though it was set at .5 W. One way to avoid that is to use an attenuator and then run the K3 closer to its normal full power. Greg

Thanks for posting. Will be starting one of these builds soon. Are you sure those bolts on the heatsink are enough? ;), I can certainly understand why you chose this amp. W6PQL is a generous guy to release all the plans and kits. Amazing. Incredible how little drive is needed. That elecraft will be very relaxed driving.

Ouch, I’ve blown out 2 making dumb mistakes. Learned my lesson at $250 a pop. I’ve built 2 now and use it every day for 2 Meter EME. I used Jim’s amp control board and it has saved me from relay failure and over temp. Enjoy...Rick AB4GS

What did the problem turn out to be?

Failure due to something I did? Definitely not a W6PQL fault.

Is there an advantage to sharing an antenna as opposed to using the IF out on the k3? 73

LOL

SDRConsole is also fine for me kzbin.info/www/bejne/oJ7Hd5V8hbuLfdU , only 6m is not working

How about 6m? is the frequency exatly the same as on the K3. After doing setup correction factor for LSB, USB, CWU and CWL all is the same, point to a frequency and the output is the same at the K3 and HDSDR. ON 6m CW is 1kcs too low and the band runs in the other direction....

What size electric circuit does ole Henry take at full power ?

interesting. How do you tie the sdrplay and K3 frequencies together? I connected my sdrplay to the IF output of the K3 as a simple panadapter but since the freqs didn't match up I never really found it useful.

Nice. Too bad you're a 20 hour drive from me. I have a 2K-3 sitting out in Philly for the last 2.5 years and that's 30+ hours away.

have you a video for setting with k3 and connect
