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?


Now with a Color TFT display! 11/05/21

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.

Short Block Chevy 350 Engine

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!

New Technology for 2020 ~ The Hermes Lite 2.0 SDR Transceiver

  The Hermes Lite 2.0 SDR Transceiver. November 7th, 2020 ~ It's Settled! It is done! The stain of the Trump era is soon to be removed! Thanks to all who voted. The Voice of the People has been heard.  Congratulations to President Elect Biden and Vice President Elect Harris. Pete N6QW November 3rd, 2020 -- IT WAS THE MOUSE   We all know this is Dump Trump  Day. Go out and vote! It was the mouse! Back in 1999 I stupidly was one of the very first to purchase a Ten Tec Pegasus. Never buy the first batch of a new model.  Touted as the world's first computer controlled radio , actually I think the Kachina 505 was really the first. But the Pegasus was fraught with problems including a trip back to the Smokey Mountains. I was using an older Windows 95 machine to control the Pegasus and that may be a co-conspirator. Well after many calls to TT -- finally someone who has some smarts told me: Fix your station ground, Make all leads short and Buy stock in a ferrite bead company. I did all

2019 ~ What is the simplest homebrew SSB Transceiver that can be built?

4/27/2019 The Future of our Hobby is Here! Forget those simple rigs with homebrew crystal filters, cranky IRF510's and the analog VFO's. SDR is the wave that is building strength just like a Tsunami. With the Soft Rock V6.3 SMD Version + RRPi2 With the Omnia SDR and RPi2 Pete N6QW How Simple & How Cheap can you  build a Homebrew SSB Transceiver? 4/26/2019 --- I just converted my websites from an obsolete Windows Based Server with GoDaddy to their cPanel (Linux). This was a cost issue as a one year renewal of the Windows Server would buy three years on the cPanel. GoDaddy is discouraging the use of what they call the Obsolete Windows System. So I had to migrate and reload the whole, and the sites to the Linux based servers. Some files and links got lost in the translation --so you might not be able to see everything! Essentially I have  to open every link to verify that it works --that may take some time
