A Scratch Built Minimalist SSB Transceiver

A Minimalist SSB Transceiver?

November 6th Update. 


Listen to the CQ WW CW Contest. Can your radio hold up in a crowded band with lots of strong signals?

First Receive and Transmit tests. Very Promising... HD8R is an Expedition to the Galapagos Islands! 11/04/21





Just as there is a difference between a 29A and a 44DD, the replacement homebrew audio amp for the eBay module certainly points the direction and stands out in a crowd. It is superb sounding with the final device being the the LM-380N-8. This will be in the final design.




The 1st Sounds of the Minimalist SSB Transceiver. I held the phone up to the earbuds to make the recording. C Change - The eBay amplifier module is underwhelming in its performance. I will have to sub in one of my homebrew modules. But this is encouraging! It does have a formal name but not a YL's name. 





These days I seem to be reflecting on the past and harken back to 1959 with an analogy. So in 1959 (I was 18) my thoughts about an ideal girlfriend was to think in terms of the minimum requirements for a YL such as could she change the spark plugs and set the timing on a short block Chevy engine. More importantly did she know what needle nose pliers were and did she know how to solder a Western Union splice joint. Yes indeed, those were the minimum requirements.

That is a 57 Chevy -- a Really Hot Car. The Girl looks OK Too ~ Healthy is a good word!


Yes , this is the official  Western Union Wire Splice!


These are not torture devices; but real Needle Nose Pliers

[ I have posted the above photos as many modern hams and many Box Top Extra's (BTE's)) who only use Facebook, would not know of what I speak.]


Likely an 18 year old kid today would have a list including: Is she hot looking, does she have money, does she drive something newer than a 2 year old car? Does she have a posse on Social Media and does she live on the better side of town?

In 60+ years the focus has shifted from skills (wrench turning and soldering) to the external environmental features (looks, money, power)

In today's world regrettably, many hams evaluate a homebrew project based on can it be found in EMRFD, does it have TIA amplifiers, does it have roots in a Bitx topology? Is it SDR based with a Teensy and Nextion touch screen display and has it been showcased on 'hackaday", mentioned in a well known podcast, has a Facebook following  or is published in QEX?  

Failing to meet any of those 2021 environmental criteria, then most of today's hams and certainly BTE's  would move on and not take a second look. Bummer! They have just missed an opportunity to experience building and using a  workable transceiver that performs well and will never see the pages of Facebook!

Unfortunately, Social Media platforms like Facebook have "trained" the modern ham to  think in narrowly defined paths which only run through these environmental aspects. That is so sad!

But suppose, just suppose you could have a design that uses the minimum number of parts with the same device in all sockets and have a working  rig, yet it never saw the light of the aforementioned 2021 Environmental Criteria.

This is a tall order; but suddenly there is now a shift back to skills and tribal knowledge! Thusly knowing stuff, you can do stuff. 

Stop looking --you can't find skills or tribal knowledge in Facebook! Today's QST won't help either unless you are shopping for a $6K transceiver from offshore!


I am taking on  this project adventure to show that you can build a proper SSB Transceiver using some very basic circuit elements. Additionally this is an in your face challenge to those who never build anything; but often speak like experts about everything. 

It does have a name; but is being withheld at this time.  You will just have to keep tuned to this channel to find out. 

In case your wondering --the YL in front of the 57 Chevy was not my girl friend!

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
