The MHST is now working on the RPi5

I am happy to report that I now have the Pi Pico able to work with the RPi5 SBC. The issue was that the package to recognize the Pi Pico has to be manually loaded into the QUISK directory. Once installed what should normally happen is that when QUISK is executed that radio should show up on the menu. It didn't on the RPi5 SBC.


It was a mystery as using essentially the same process the radio did show up on the Windows 10 machine. Then, I decided to closely read the instructions where I spotted something you needed to do differently for the Linux install. Dah RTFM! Suddenly the MHST rig is in the list. I still have a few warts to polish off but a huge step in reducing the size of the rig with the bonus of the features in the Linux form factor versus the Windows 10.

One really important Linux feature is the Pulse Audio Control Panel that is loaded in a terminal like this.

sudo apt-get install pavucontrol

This control panel gives you a whole series of adjustments and selections with regard to the two sound cards. This panel has the Mic Gain and overall Audio gain level sliders as well as the line levels for the I/Q channels on both transmit and receive. #11 is not always the best adjustment.

I did find with the package developed by the VWS that some sound items on the QUISK configuration menus do not show up automatically as a drop-down menu but must be added manually. I cannot fault their package as I am using their software for a completely different application and rig. The manual entry process did work.

Another issue was the Com Port. In the Windows 10 I was able to determine the 2nd Pi Pico is now com22. The 1st Pi Pico, I smoked, it was com21 and those com ports must be manually entered in the QUISK Configuration set up. The Linux com port is a bit trickier and is entered as /dev/ttyMACO

It is basically there but there are still some features requiring a bit more work and so we press on.

It is understood that some big thing will be announced from 1600 Pennsylvania Avenue on Tuesday -- how appropriate as that is April Fool's Day. T. S. Elliot, a noted American author and poet once said that April is the cruelest month. Maybe Tuesday's big news is more in line with T. S. Elliot. 

Where do all those who were RF'D go for employment. There is a timing disconnect between tariffs to create more US businesses and when those businesses would be in full production to absorb displaced workers. Two years is a very optimistic time horizon. Surely someone who attended Wharton would know that (from Econ101). So, what do us common folk do for two years?

Keep in mind those who were RF'D were not bad employees, yet they are categorized by one individual as Waste, Fraud and Abuse.

Them that know can make it go.

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
