Re: Anti Static soldering mats

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

Re: How do I best operate a 4S-Tuner with a Doublet antenna ?
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: Anti Static soldering mats
Hi there,
I sensed that there was a bit of confusion regarding ESD mats and I would
like to clarify a few things, if I may. BTW, I work at an electronics
equipment factory and I wear an ESD wrist

Re: How do I best operate a 4S-Tuner with a Doublet antenna ?
Sounds like a Norcal Doublet....

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

I would love to participate. I am OK at abt 12wpm. However, my 7122 xtsl is actually 7121.1. I have a second 7122 xtal that tests out at 7120. I have my Bayou Jumper. I might have my SDR Cube on
