June 5, 2024. A Bit of Nothing Today.

Don't read today' s Blog. Just some bits and pieces for me to share but no Technical stuff and no CRAP (Cool Radios And Projects)

One bit of technology however that I found really interesting, a result of my interest in personal care and now I share with you. All of us should have a concern about our health from eating properly to exercising and extending that to annual physicals and routine check ups.



I do that religiously and one test currently in progress is the wearable heart monitor that is about the size of a Timex watch. They glue this thing to your chest and you wear it for two weeks where it measures your heart parameters.

That in itself is amazing technology. Along with the monitoring you have an option to write down in a small book provided you, any time you sense any symptoms such as a rapid heart beat or dizzy spells.

Now this is where I saw brilliance and stupidity. Optionally you can scan a QR code and manually record these same events on your phone. At the end of two weeks  you rip off the monitoring device and mail it back to the supplier of the monitoring unit where the data is downloaded and a report provided your doctor.

So the stupid part. Why not set up the whole test so the normal process is that you link to your phone with Bluetooth and it is all automatic where the data collected is routinely dumped over the internet to the suppliers computer. In fact should an event occur that is life threatening --automatically 911 rolls.  That my friend is called real time monitoring! The hardware structure is there so why not?

But that is not unlike our radio gear. Recently I showecased two products from Xiegu, the G1M and the G106C SSB Transceivers. 

The review of these products (somewhat non-technical) noted that there was no way to adjust the Mic gain either by a physical control or a hidden menu. 

Also noted was the cheapo microphone that would need replacement in due course. So if you had a microphone in the junk box --its level could be too low or too hot but no gain adjustment to accommodate that mic. A problem -- so you would have to find an exact replacement of the cheapo supplied unit. Why?

We can all think of other examples where common sense would tell you that what is there certainly falls short of the mark. The same with our health -- common sense says take care of yourself.

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 ...

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...

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
