One of the poorest moderaterated forums I've ever seen. No need to reply, I'm gone.

Something along this line? https://smile.amazon.com/WGCD-SPDT-Momentary-Button-Switch/dp/B07D1HSN56

Sounds better than Auxilliary Power Plug.

This is more on the theory of polyphase networks. http://antennoloog.nl/polyphase-networks/ 73 de LauritsF, NT1G

Pretty much self-explantory 1pps pluse generator from a single cell clock.

Modern lpfs on cqx 'softens' the square wave transmitted. The traditional lpf is much too high in cut off to prevent a 20 M signal from blasting 10m. If the amplifier is a 'linear amplifier'...it need

Traditional lpf were intended to limit TVI...on the transmit. Modern lpfs are used to limit the RF into SDR rxes.

Won't you have to evaluate the harmonics on 80M to evaluate a 160M lpf/ toroids? 73 de NT1G Merry New Year!

Ever consider putting AIRBAGS on a motorcycle? Just a thought? Merry New Year!

I think IF you are just testing inductors or caps... this is what you can use. https://smile.amazon.com/KKmoon-Secohmmeter-Capacitance-Frequency-Inductance/dp/B082VBTM3H Looks indentical to my AADE l/

What makes an AADE LC 'display' better than the ones available today? Soldering/assembly skills? Single point failure? 73 de SkipF, NT1G HO! HO! HO!

Thanks! It's now time for me to wind my 'smart watches'; pair of seiko 4R36s. No battery included. Skip, NT1G and a Century22 (still)

Oh, yes...and I'm also working with the CORDIC algorithm... AKA the slipstick killer.

I've learned it's easier to apologize for any spelling error than it is to fight with a spell checker. And I can still use a dictionary, straight key and sextant. 73 de NT1G

I'm using an HP laptop supply to run a 50+50W Bluetooth AUDIO AMP board I bought from 'amazon' for $13. The speakers on my 'tablet' aren't 'hifi' and this board has four screw terminals for 2 speakers

Another list member (me!) want to know...do you have any inductance meter or bridge? I takes a lot of guessing (and doubting) out of the picture. Skip Flem, NT1G Boston-ish

QRPLABS is NOT a YAHOO group.. It's like driving a Mercedes and Chevrolet says they are dropping your warrentee. Whoop Dee Doo.

Great news. I have several spools of 'Phelps Dodge' copper products. All HAPTZ (the good stuff). Where did you buy this colored wire? THANKS for the info.

Never seen magnet wire available by color... Perhaps a task for a 'sharpie' marker?
