March 3, 2024. From Whence Cometh Radio Innovation?

When I was an Ensign in the US Navy often, I would get orders that just didn't make sense and I would say (under my breath) "Who in the hell thinks this stuff up?" Often the answer is surprising. As a Lieutenant I was surprised to find out the answer for one order. 

The CO calls me up to his office one day and says to me "Pete, I want you to form a Seabee Band and with the best of the players a small Dance Band?" Aye, Aye Sir!

I did just that as it turned out it was not too hard to find quality musicians as being in the Seabee Band was the alternative to a mount out to South Vietnam.  I found a Chief Petty Officer who played sax in Woody Herman's' band and so we had a key player.

The dance band was also formed, and their debut was opening night at the Port Hueneme Seabee Officer's Club.  That is when I got my answer. It was the CO's wife! It seems the skipper and his wifey were former ball room dancers and she missed that venue to doing some serious dancing. You never know from whence the order comes.

Thus, our subject of where radio innovation starts, and I sat down and prepared this chart.
 
This was an eye opener for me and likely I forgot some manufacturer, but this shows not the coastal guys, but the mid-west has the majority. One or two started in a garage and the rest is history. But that begs the question as to why.

I wondered about a company like Ten Tec who had a start-up in Tennessee (Dolly Parton Country) and formerly produced some high quality and innovative radio products. Having had some personal experience in setting up a manufacturing plant in Melbourne AK, I think I know why. 

The answer is that the workers often came from a farm background where problems were aplenty, and they were the only path to solution. There was no help line or 800 number (which actually is in Indonesia). They had to figure it out -- and they did. I also think it was inherent in their upbringing about being self-sufficient and not giving up. 

Sadly, today most on that chart are gone with only two who remain technical innovators one in the mid-west (FLEX Radio) and a left coaster (Elecraft). I am not certain if Ten Tec is still active under their new ownership so there may be a third. 

In case you wondered this is a Morrow radio receiver from Oregon.



 
In mind, the left / right coast "think tanks" like Stanford, Cal-Tech, Harvard and MIT may have come up with the theory part, but it is the mid-west who turned that theory into radios that even today are in use. (Gulp, my boat anchor stable includes Drake, Collins, Hallicrafters, Swan, Ten Tec, SBE and National.)

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...

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 ...

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
