More Transceiver Projects

Image
Yesterday I received an email from Jim up in 7 land inquiring about some Arduino sketches and problems compiling the sketch. I think some of the code was provided by me. I too at times have noted some issues with sketches that previously complied "slick as anything" but then started to hiccup.
Has any one heard about Arduino code that may contain viruses?

SS Podcast #210 we talked about the Vintage Sideband Roundtable ~ at any minute smoke and flames can come from an old boat anchor. It is true!

Search this blog for the Simpleceiver and you can see the painful detail on how to build one. The other day I was thinking about the original Simpleceiver and how that I still had most of the prototype boards still screwed down to a chunk of wood. Frankly I was OK with the 12.096 MHz crystal filter but still felt it has some short comings. So then I thought about popping in a 9 MHz GQRP Club Filter in…

An Arduino Discovery and a Mystery

What should be clear is still veiled!
So OK I have a lot of transceivers that I have collected with most being acquired on the cheap. So while there may be many, the invested dollars are relatively low. Periodically I will drag one out of the storage bin and try to fix the unit. This is done more so as a technical challenge; but often I drive myself nuts in the process.
Here is a recent example. Several years ago I bought a Ten Tec Triton IV Model 544 which is the digital version of the Model 540. Several years ago I actually converted a 540 to a 544 and you can see that on my QRZ page. It was also a subject of an article that appeared in QRP Quarterly. Thus I have a bit of background with this very FB Ten Tec rig.
The Model 544 I have supposedly was hit by lightning and was inoperative. Well that was true; but not a total disaster. (That is why I got it so cheap.) Replacing two back to back diodes that were shorted ahead of the reed relay that disconnects the receiver during transmit cu…

So How To Do CW on a Homebrew SSB Rig?

3/14/2019 ~ Calling All Junk Boxes????
Calling all Junk Boxes, N6QW is looking for a part!
Recently I bought an SBE-33 SSB Transceiver for $52.30 and have been doing some major restorations, which principally involved a great deal of capacitor replacements. I did have to replace the speaker which was blown; but had an exact replacement taken from a Junker unit. 
I have had the rig on the air and so far I am impressed at the 1963 technology --even with an analog VFO. Yesterday running my SB-200 I worked Croatia, 9A5W, Nikola on 40 Meters. That is a big first for me and I got a notable report of how good it sounded. 
A short story --- the dial markings are at every 5 kHz and a ham running a FLEX5000 contacted me to tell me I sounded bad and was not on frequency (7.208 MHz). I asked that he give me some chatter wherein I zero beat him. Then when I transmitted back at him inquired about the signal. He said I don't know what you did but you fixed it. You ar…

You Know You Are Gettin Old When ...

Stop Reading this has nothing to do with Ham Radio Stuff!
In a bit of wistful reflection, these days I am taking a more measured approach in what I do.
Take this morning when I was responding to renewing my AARP membership and checked the one year renewal period. I was thinking hey in five years I may not need this --maybe not even three.
Then I thought about what happened in the grocery checkout line yesterday (I was wearing my beret) and the rather attractive lady in front of me had a few items and her total amount was $19.56 wherein I blurted out --that was the year I was in the 9th grade. She turned to me  and said well you don't look that old. (I just know it was the beret).
Then I had a conversation with Go Daddy yesterday about the renewal of my hosting account and the five websites. They were trying to encourage me to sign up for three years. Again my thoughts about who knows if I will still be here in two let alone three years.
That gave cause to my penchant these days to NOT …

The $52.30 SBE33 Boatanchor

1963 ~ Lots of new SSB Transceivers!3/5 Late Update ~ On the Air w/SBE33Well what I posted this morning was a good exercise but it turned up  different problems. The driver (12DQ7) was bad and the reason no indication --- the meter is broken. Upon close examination I saw some very thin wires floating around. One option is to find a company that rebuilds meters. I just set the bias for maximum smoke and we get > 60 watts on tune. Made a contact on 40M with a station in the SF Bay area. Got a good report. We are cooking with gas!

3/5/2019~ Happy Birthday To The US Navy Seabees!
On 5 March 1942 the US Navy Seabees were founded. So to all who "Can Do" hoist a few and Happy Birthday!
In yesterday's post and in the video I mention that I saw no current and no output after fixing the HV supply problem. I guess I was so involved in the many fixes that I didn't take time for a bit of noodling. My brain works while I sleep and so this morning we now have a theory as to the why…

My First SSB Transceiver ~ 1963.

Image
I was asked a question...
A ham in the Mid-West with a "1" call frequents 40 Meters making contacts and always asks during the QSO "What was your first rig?"
I responded with my 80 Meter ARC-5 and the one tube Tx (6V6). But then I thought about my first SSB rig. It was the summer of 1963 and had just graduated from college and simultaneously entered the US Navy as an Ensign. My temporary duty station in Port Hueneme, CA was a three month school that focused on overseas construction and a dose of how to harden structures to survive a nuclear blast. (It was 1963). 
There was quite an active ham population on the base given that each Seabee Battalion had a complete Collins station that was activated during overseas deployments. KR6SB was the Seabee station on Okinawa. 
I happened to mention to one of the chiefs who ran Special Services that I was headed to Midway Island for a one year tour. He said "you need to take a rig with you and we have a deal with National Rad…
