That Banner should be part of the Resource Page...….. be a shame to loose it in the archives of newsletters.

Good tips,

I worked for over 30 years as an electronics technician, and that's the first three-legged transistor I've seen with lettering on the back side of the device! I can see where this situation could be confusing. In my opinion, you have Q2 installed correctly. When you look at transistor datasheets, the manufacturer shows the pinout according to the shape of the device, not the lettering.

Interested in your experiences and tips using the FT-817 and MiracleWhip antenna

Dr Jim Kennedy
 

 

I am very interested in your experiences and tips using the FT-817 and MiracleWhip antenna either indoors or out? Did you use a counter poise and if so what length? Also, distances confirmed using this setup.

I have used on CW and have logged QSOs of over 450 miles with simple 23' wire counterpoise on 40 meters.

Look forward to hearing your experiences.

Thank you very much.  I will double and triple check my orientation and try to correct the orientation, if needed.  But, I have already lost a solder pad and am not sure how many more desoldering/resoldering attempts can be made on this component.

This is a good excuse to do a little engineer/detective work involving the schematic and the data sheet.

The schematic shows that the Source of Q2 is to be connected to the ungrounded side of R8.

The data sheet (see message # 22052) has a pictorial that identifies the Drain, Gate, and Source leads unambiguously.

Close examination of the PC board shows a trace, on the top side of the board, hiding under that black solder mask, from R8 to one of the pads of Q2. That pad must be therefore be intended for the Source lead, and all the rest will fall into place.

Of the two flatted sides of Q2, the wider one must face towards the blue resonators - as shown in a couple of posted pictures.

Tongue-in-cheek aside to Dave, NM0S ...   When you get to the Pearly Gates, Dave, and I have no doubt you've earned your way in, St Peter is going to look in his QRP logbook and exclaim, "Welcome NM0S, but... why, oh why, oh why the fascination with black solder masks?  We usually send those to the repair techs in that 'other place' as their pennance"     LOL

Re: 75A

So, the Q2 component has writing on one side but is flat on both sides. It’s not shaped like a Capital D. 
I installed it with the side with the writing on the flat side of the D. Like in the silk screening. 
Now that I know that is backwards, I removed the component with some difficulty. I managed to remove the pad on the bottom side of the board. I replaced the component turned around with the writing on the opposite direction with the writing facing the speaker side or the rounded side of the silkscreening “D” .  The center leg is soldered from the top and the two legs are soldered from the bottom. But I see no change in power when tuning it. 

In fact I’m afraid I might have had it right to begin with. But won’t now be able to change it back. 

Can some one help me with this?

 Sorry for this seemingly elementary question. But, as this component isn’t shaped exactly as others, I want to make sure I’ve installed it correctly. 

There is writing on one side of the component and no writing on the other. With the heat sinks on one side and the speaker on the other, which side is the writing side to be facing?  Towards the speaker or towards the heat sinks???? 

Please,

Tim

The Q2 silkscreen on the 75 and 75A is backward.  The rig will work with Q2 backward, but power output will be reduced.
