The 1MC ~ AKA the "The Bitch Box"

 The 1MC AKA ~ The Bitch Box.


For those who served in the US Navy especially aboard ship the "1MC" is the Main Audio Communications System that is used for communicating to "All Hands". 

You have seen it in the Movies -- The CO gets on the 1MC and announces, "Now Hear This! This is the Captain Speaking". Sailors being sailors gave this a nickname -- "The Bitch Box" as many of the messages dealt with complaints or commands. 

What shipboard Navy man doesn't remember the sound coming over the 1MC: "Sweepers Man Your Brooms, proceed with a clean sweep down fore and aft"?

All of us have heard the civilian version of the 1MC when we visit Wal Mart or Costco in the form of the PA Announcement. "We need a cleanup on Aisle 6". 

These days those same words have come home to my QTH. In effect, my home is Aisle 6.

My XYL was in hospital for two months earlier this year and although at home is not fully recovered and may not be for some time.   So, I along with hired staff get to play caregivers with me doing about 60% of the effort when the hired staff is not here. 

Reflect back on the war in Iraq and Afghanistan when many of our troops suddenly were exposed to the IED (Improvised Explosive Devise). Well at the N6QW QTH, we now have the IDE (In Diaper Explosion). I know this sounds gross in a ham radio blog but it none the less is a reality of life. So perhaps my blog is my form of 1MC. "Now hear this we have an incoming IDE in Aisle 6". It is OK to laugh!

Believe it or not I find that humor is a great coping mechanism, and my caregiving has taught me a whole lot about PPE. I have regular orders of rubber gloves, KN95 Face Masks, cleaning supplies, and medical aids such as foot operated pedal bikes. A new skill is to swap out the small oxygen bottles in less than 20 seconds. 

The key to remaining sane is the use of disciplined processes and to think three steps down the road. My formal engineering training has really paid off. 

Sadly, there is little time for ham radio either building rigs or even operating. But I have found that arising at 3 AM does provide about 75 minutes of free time to work on stuff before the daily processes takes over. 

I now find that many of my projects that were say 95% complete can now be recycled to finish off that last 5% -- and are good candidates for the 75 Minutes of normal time. One such project is the Spilsbury Tindall Replica rig. 



This was how it was left (95%). I thought the yellow background on the frequency display looked harsh and should be "rounded" and there was no S Meter. BTW that is a 2.4-inch, ILI9341 type display with a lot more pixels than the 1.8-inch ST7735 type.


The display has been "Rounded" and we have added an S Meter which is still to be added in 'hardware' but the display part is in the software. I am hoping for another 75 Minute window to do that piece.



I note that the audio output (fed into an external amp) has a bit of a raspy sound. Need to add that to the list of further review/evaluation. The IF Module is the Plessey Amp version and the whole module is SMD.

Never lose your sense of humor and I must now retreat, as I just heard the call on the 1MC "Incoming IDE on Aisle 6".

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 pastapete.com, jessystems.com and the n6qw.com 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

2022 ~ Building a SSB Radio Transceiver ~ Updated 1/31~ Final Capstone

Building a SSB Rig (Radio) in 2022 [A word Document of this total posting can be found here   PLEASE NOTE this opens to the home page of my website and staring right you in the face is a LINK to the document. The link is "How to Build an SSB Transceiver with a Date".  As I update the document, I put the date in the link so you know as of what date -- today the link will change to January 31, 2022] Updated 1/31/2022 ~ The Final Capstone. The above photo is of a Tri-Band Solid State version of the Heathkit HW-100/HW-101. It uses the SSB Filter, BFO Crystals and the Heterodyne Crystals straight from those radios. The rest is N6QW magic. You can read about this project on my www.jessystems.com website. Even the panel meter is Heathkit. BUT the PTO is from a Ten Tec Triton IV. An added touch -- the LCD Display. But this photo is a constant reminder that when you are at this stage is NOT the time to think about an enclosure to house all of that hardware! Regrettably it was an after

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
