I uploaded a file that contains this advice… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner –

I will release more on this project this coming week… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois

I’m replying to the note attached below (attached for context)… Here’s where I am with respect to the T41 Project. I just returned to the USA (last night after midnight) after two weeks at my

Ah, very nice - I hope I manage to have a QSO with you then ;-) 73 de HB9HEI

Thanks for the update Bill. Good luck in contest. 73, John KE2AMP

No i have an alternative life as a contester and to that end have been at my contest station J68HZ in the Caribbean for a couple of weeks getting it in shape for CQWW. Ill give an update when i get

interested also in the progress of the control board for the amplifiers. [email protected]> wrote:

Hi all, havent seen any talk lately. Just wondering how it was going with the 100watt amp kit/testing? Regards 73, ?John ?KE2AMP

Bill, I use the PE4312 to control the TX Drive in my 2022 SDR Transceiver. The implementation was per the PE4312 Datasheet ( https://www.mouser.com/datasheet/2/281/pe4312ds-1517840.pdf ) , including

Ya das is richtig! Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner – Operator Villa Grand Piton

nope .. the trigger from the rig (positive 3 to 12v) is the power supply in this case never seen an "open collector" output?? (any ptt circuit pulling to ground does this) dg9bfc sigi Am 19.10.2023 um

What do you need a power supply for? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner – Operator

I think there is an error in the drawing . No powersupply Met vriendelijke groeten Jean-Marie Www.on7en.be

No… drive the gate of the IRFI630 and its inverse… I shudda put that on the schematic too… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big

Here is what I’m using in the T41. It’s good to 250V and 2amps. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC

Thanks all! Since I am trying to continue supporting the Nano (very criptled because of flash size), I don't have an extra GPIO pins. So will use the transistor with a current limiting to do the

WRT switching negative/positive: Here's a link to the manual for that keyer. The schematic is on page 21. The PTT circuitry is just a pair of 2n7000 MOSFETs. The keyer is cased in a plastic box. I'm

Hello Mark, Inversion of the signal is simple - it can be done with a single NPN transistor and one resistor. Your output turns on the transistor, and the resistor limits the base current. It gets
