Wire Wrapping

Security Check: Alexa Off, Tape over the Lap Top Camera, Mic on Mute. No doubt you are being spied upon! The spy could be a governmental or non-governmental agency!


A quick way to construct circuits, far advanced beyond the archaic chunks of copper PC Board and superglue is to use prototype boards and wire wrapping. 

First, a disclaimer as wire wrapping is not suitable for RF circuits but really shines when using ones and zeroes in the digital world.



I am covering this subject today as wire wrapping is the process I am using to build the Digital LO / BFO for the 20M Hybrid Wireless Rig. 

Firstly, wire wrapping is over 60 years old as a technique and thus mature as a process. The wire wrap process is simple and involves a more or less square pin and using a special tool the wire is tightly wrapped about 10-15 times around the pin. The square pin has sharp edges, so the wire grabs around the pin and won't slip off. A round pin having no edges we find would not securely hold the wire.

Our ESP32 VROOM MCU has 38 pins thus a single header cut in two makes sockets for one device.  A pack of 10 costs about $10 so enough material for 10 ESP32 devices.

Should you make a mistake it is fairly easy to "unwrap" the wires and the bonus no soldering of wires.

Them that know can make things go. Them also are vigilant about unwanted surveillance like trackers that follow your internet meanderings. Norton and McAfee have software to fix the trackers. No kidding this is 1984 in 2025!

January 26, 2024. A simple CW Transceiver/Transmitter

Cruise through the lower part of the ham bands bands and what do you hear? Well, FT-8 and CW. Often you will not hear any SSB stations yet go to the lower part of the bands, and it is a cacophony (I love that word) of bad sounding signals and some high-speed keying. Fast is not so much of the issue as is bad, run together and jerky keying. But none the less our hobby started there.    So, you could crank down your ICOM 7300 and watch the waterfall on CW or you could homebrew a radio. Actually, to do CW right you need more thought up front than you do with a SSB transceiver. Often, I will state that a CW Transceiver is much more difficult to build than a simple SSB rig. I published two articles in QRP Quarterly on CW transceivers and all I got was a yawn so maybe history will repeat itself.  Yawn!   30M CW Transceiver with RIT!   Of interest is that the LO is a Varactor tuned LC oscillator using a NE602. Look closely at the RIT circuit which is only activated on ...

March 31, 2024. Happy Easter to those who celebrate this day.

What a great day to Binge on Chocolate and experience the pain of that filling that has been leaking.  I would be in that category with the leaking filling(s) had I not just spent an amount equivalent to one of the fancy new uptown appliance box transceivers on two filling repairs. Well at least I can binge on the Chocolate bunnies without fear of pain. Regrettably everything appears to have jumped in price including the price of parts. Well not so much the parts as the shipping costs.  That notably is seen in the eBay treasures. I spotted a nice heathkit DX-20 for about $50 and the shipping was $65. Likely it is a twofer with part being a way to in effect charge a higher price by inflating the shipping and in part by increased shipping costs. Shipping with insurance across the US was about $150 for this jewel and that was three years ago. 6AM on the Left Coast ~ 20M Easter Sunday! My only hope is the cost of Chocolate Bunnies remains steady although a pound of See's Candies f...

August 30, 2024. A PNP 20M SSB Transceiver

Shown below is the Block Diagram for the 20M PNP SSB Transceiver steered in the  Transmit Mode . The components shown in the dotted block are relay steered so that the block module is single pass and amplifies in a single direction. The Block diagram show steered in Transmit.  Essentially the steering process works so that the IF Module input follows the Balanced Modulator on Transmit and then the input side follows the Receive Mixer on Receive. All done with some relays and a bit of RG174U coax. For those who count things in detail, this block diagram is not unlike what was used for the PSSST Transceiver which can be found on my website . Yes, a warmed over P3ST only using PNP devices. TYGNYBNT. 73's Pete N6QW
