Cesar, When I get back to town and my bench I will check and tell you. Raj

I just wanna be able to output 5-10w on 28mhz.... not 1w... My QTH is pretty remote and without "decent" power, I wont get any contacts on >7mhz... Might have to seriously consider an FT817, but the

Did you re-bias the 510s when you changed the PA voltage? If not, theoretically this could happen if the bias were set right on the edge of class “C” operation. Dr. William J. Schmidt -

Somebody already did the amp for you: ? ??http://w6pql.com/1_kw_sspa_for_1_8-54_mhz.htm#rfdeck Unfortunately, it requires 2 or 3 watts going in for full output. So we still have to bring the uBitx

Yes it does, I never would have figured that out! I wanted to include that appropriate CAL value in my version of your sketch to pretty much get it calibrated correctly when restored to those

Touching back on this, it's feld-hell's lower duty cycle that was causing the lower current draw. -- ---------- N5WLF, Greggory (or my nickname, Ghericoan) General Class, Digital Radio Hobbyist

Check this socket trick below that someone else posted. Then fold the RD device over and screw it to the case. Tab is not hot any more. Re-bias. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK

RoboDyn is a good outfit...even though they have little to do with the Arduino outfit. Ought to work well if you get a genuine RoboDyn unit. It has a CH340 interface and micro B USB connector and is

Well, it's nice. But you still have to design the amp. And blowing up one of them is a whole lot more expensive. Hi. Let's see...I could get about 42 RD16HXXX devices for every one of these. And if

Oh, just bite the bullet and go QR-Oh-Oh-Oh!! HiHi https://www.rfparts.com/blf188xr-amp.html 73, David KB4FXC

I got mine from RF Parts in 2 days around $5 each. I also got some of the RD16HVF1's (good through 2M) as well. They were only a tiny bit more than the 30MHz HF parts (less than $6 as I recall). I

NO cheap, but what about: https://www.minikits.com.au/eme210.htm Like this: 73, Nick, VK4PLN

Bill Glad my own uBITX work could be of value to someone else. Arv_-_ Sent from my Verizon, Samsung Galaxy smartphone

Arv, I am glad you went to the trouble to post this. I have been puzzling how to do this myself because the switch connection did not make sense to me. Your sketches reflect the way I thought I

That is where I placed my second order. The other place was closer and I should have had them in a couple of days... oh well. Marco - KG5PRT

the Parts Place is a good place to get some. But they are now on back-order. Also, it is noted that the prices have increased (~$US5.00 for RD16HHF1). It looks like the market is catching up with

I am still waiting for mine. Second order, last oder sat for over a week until I asked about them and was told they were out of stock... So much for customer service. Marco - KG5PRT

PA1FOX has done this, but I don't think he has posted detailed results yet. (He has promised to do so). I have some, but have not gotten around to finding out what they do. It looks very good,
