2018 ~ The Year of SSB Transceivers

Coming September 19th, A New RIG!The Sudden 40 Meter Transceiver (Design Data Provided for 20M)
I was advised that the latest SPRAT is in the Royal Mail and so later today on my website I will upload supplemental information on the Sudden SSB Transceiver. Part II which covers the transmitter elements will be "live" when Part II is released for publication. As will be evident once you read the article and the website -- building the receiver section puts you well on the way to the transceiver configuration. Hopefully once you read the information you will say --" I can build that rig!" If you have joined the GQRP Club  your very own SPRAT is on its way to you. 
Yet, another exciting project from the N6QW Radio Laboratories.

9/15/2018 ~ Some Specifications:
Minimalist Circuitry ~ not a Bitx Knockoff! 5 Watt "Ionosphere hole burning" output. Two VFO's ~ All done with the Si5351. Upper and Lower Sideband Panel Selecta…

Using the Digital Modes WSPR & FT89-11-2018
Some nice spots into Africa and South America. Am using a new site for displaying information. This site also has analytics about your spots. Thanks Phil, VK7JJ.

This is about 15 minutes this morning, 7 AM PDST, running 10 watts on 40 Meters and a droopy dipole. You can see the paths favor NE SW and are pretty consistent even running 5 watts. Some of those paths are in excess of 12000 KM.
The secret is the newly designed and scratch built digital interface that can turn any SSB, USB capable transceiver into a digital workhorse. Unless you modify the Bitx40 it will not work without modification to USB. Most of my rigs are homebrewed by me and thus are USB capable.

I modified a sound card interface board from KF5INZ (eBay) which used a Serial Port for communication with my computer so now the lash up works on USB. The computer is a small form factor Windows 10 Intel NUC that is about the size of a CD case…

FT8 & WSPR on your Homebrew Rig!For several months now I have been working on a new SSB rig that will be the subject of a couple of articles in  future issues of the GQRP Club publication SPRAT Magazine.

Run don't walk if you are not already a member of the GQRP Club so by joining you can gain access to the articles. Most of my operation is on SSB but I have come to recognize that many in our ham community have moved over to the digital communications dark side and therefore challenged myself to enable my SSB rig design to "do digital". I am happy to report that I have been successful in running both WSPR and FT8 from the new rig.
All that was needed was the software WSJT-X, a $10 (delivered) sound card interface board, some cables and an old computer with a serial port DB9 connector. That is it. 

With technology advancement comes change. Most new computers do not come with a serial port and thus that presents some difficulties in using the sound card interface device. …

Something for the SDR Crowd!
You too can build your own SDR Transceiver!

Second Generation Main Board

The board above is a second generation board and contains the two ADE-1 Detectors and the Modem coupling transformers, the divide by four 74AC74 and to be installed is the band pass filter. If you look close you can see the ferrite core balun used to split the signals going into the two detectors. This is a deliberate attempt at isolating signals and keeping things neat and tidy. I am thinking about a separate enclosure just for this board. Later today I will install the bandpass filter with the intent that it may be used at 9 MHz with a possibility of a different front end. You will have to stay tuned for this.
How about using the SDR on WSPR?

While I can claim I built this rig and added several modifications, by and large the credit goes to Charlie Morris ZL2CTM for his design and software development. You can follow ZL2CTM on YouTube and he has many videos and tutorials!
The bottom line…

Boat Anchor to Silk Purse.

Start looking for some old boat anchors as they offer possibilities for upgrading to modern radios.  Right now I am personally trying to locate a reasonable condition, reasonably priced Heathkit Hot Water HW-32 or HW-32A. The plan --Color TFT/Arduino/Si5351 upgrade so it will have full band coverage and offer switchable sidebands. Possibly even CW with the 3rd Clock. Email me at  if you have one of these rigs hiding in your garage and are looking for a new home for this jewel of the 1960's. Remember reasonable condition and low cost. If I can do this to a HW-101 just think what a HW-32 or 32A would look like.

7/29/2018 ~ Arduino Code for LCD to OLED replacement http://www.n6qw.comLook inside the Purple framed text for the link to the code. You will also have to have the included files -- see the notes in the sketch and as mentioned below. If you are unsure on how to do this … don't try it.
73's Pete N6QW Secrets Revealed: How to Add a Tune Tone and CW Identifier to your Homebrew Rig. 7/27/2018Disclaimer: I am not a software programmer nor do I profess to have those skills but I am a person who likes to tinker with things. For several years now I have had a Pulsed Tone TUNE capability with my rigs. I developed the code myself and even figured out how to change the screens to show you are in TUNE. For those who do software on a daily basis --you probably snicker (a lot) at my code. Frankly that is unimportant in that what I developed works!
So today I said to myself "Pete why can't you add a CW identifier following the pulsed tone?" So I did and it works! How this works is …

6/21/2018 ~ 6 and/or 4 Meters Your Band?

Yes you are reading that the displays are saying 6 meters or 4 Meters. There are many possibilities with the Arduino and Si5351. These are but just a couple examples. No, the 6 or 4 Meter hardware is not built but if you have such rigs and need a sketch email me

6/18/2018 ~ More Possibilities

The code has been ported over to the Color Touch Screen and the 160X128 Color TFT. Lots of possibilities!

6/17/2018 ~ New and Improved Code(Up on the link)
No Flickering of the Display !~ Thanks DuWayne KV4QB!

6/16/2018 ~ Two VFO Code: 160X128 TFT
Follow the link and look for the Simpleceiver project. There you will find a link to the code where the code is a notepad document. Copy and paste into an Arduino sketch. Note below:

5/6/2018 ~ Update
Here are some photos that have survived ....

The above photo is the "Officers" shower facility and the man near the right hand center of the photo is taking a "whiz" into an outdoor urinal. This device invented by the Seabees is comprised a 12 inch diameter piece of PVC pip sunk into the sand and that is it. I must admit that after a few drinks the 12" target was hard to hit and the same problem late at night.
The next photo taken in 1965 should conjure up thoughts of the movie and TV series "MASH" -- I think the movie stole our lifestyle. That is my rack in the corner of the hut. Please note that my 782 Gear is packed and at the ready. Oh there are those asking what is 782 gear. Well the Seabees worked closely with the US Marines and adopted many of their processes and procedures. The term 782 refers to the form used to delineate the field gear that a US Marine (or Seabee) is issued. Typically this is a pack, helmet, entrenching tool …
