Re: OzarkCon video
Kevin K9NSE,
Great job! A true labor of love and respect for the hobby. Your arms must still be aching after all that rock steady "Armstronging" of your phone/ camera Kevin.
Hope to make OzarCon

Re: How do I best operate a 4S-Tuner with a Doublet antenna ?
Hi Bob,
Antennas are the magic part of ham radio.
Your 4sqrp tuner is a great one, basically designed for use with a "random length wire" antenna and a counterpoise wire.
For portable use, the antenna

Re: Eagle Parts Library for QRP projects?

Re: Eagle Parts Library for QRP projects?
The Sparkfun libraries are a good resource for getting started.
I use Eagle extensively, and generally Mouser has libraries available for most parts they stock. I usually order most of my components

Re: Anti Static soldering mats
Bob,
ESD mats are for benchtop usage.
The same applies to the Craft E Mat or the Kasis S-140 previously mentioned before.
Large ESD floor mats or even ESD floor paint exist, but they are mostly

Re: Eagle Parts Library for QRP projects?
Hi Curt,
Like you, I prefer to have enough copper on the board to be able to work with it easily.
For something like a DIP package, the lead spacing is 0.100" The drilled holes are about 0.040"

Eagle Parts Library for QRP projects?
At age 71, decided to attempt learning how to design a PCB for fabrication by the numerous available shops. Selected Eagle, using the free version at least for starting, managed to draw a schematic

My apologies for responding to this posting after having responded to a

I did investigate the Kaisi S-140 mat offered by Amazon.

Hi all,
Thanks for the replies.
Frank, you mentioned a 4:1 balun. If I am connecting the 2-wire feedline directly to the tuner binding posts, how do I make / find a "bal-bal"? Or, are you

Re: How do I best operate a 4S-Tuner with a Doublet antenna ?
Sounds like a Norcal Doublet....
https://www.n5dux.com/ham/files/pdf/NorCal%20-%20Doublet%20Antenna.pdf
4S tuner is designed to work best with random wire antennas.
But I'd try it anyway.

I guess I need to reiterate that everyone participating in the SSS should think about those with Bayou Jumpers (and other rock-bound rigs) and scan around 7122 (+/- 1 kHz or so) and other 4SQRP
