TX Relay, Power and TX REQ IN

Wiring the Break Out Box and TX-REQ-IN

So I used my last spare plastic project box, some female phono jacks and found a push-button that I'd cut off of some other project in my junk box and went to work.

I used some shrink wrap for the momentary switch for the TX-REQ-IN pin.

I wired up 3 phono jacks... One for the TX relay, another for the +12v out, and one for the ALC control in case I ever do get an amp.  I safed the other wires for future use inside the project box.

Partial Success

Unfortunately, the TX-REQ-IN does NOT do what it does with other Yaesu transceivers.  Pressing the button grounds the TX-REQ-IN - the radio does transmit a carrier in any mode (here I tested with LSB) but rather than transmitted a reduced power carrier as it's supposed to, it just transmits at whatever wattage the mode is currently set to.  In this case I had the power set to 50w into a dummy load and it transmitted the full 50w rather than a reduced power 10w or 20w carrier for tuning.  See the power out on the radio's display

A number of years ago I purchased a Raspberry Pi intending to do something with it. Well, it sat for many years with me now and then taking a look at it and thinking someday I will explore the Pi. A few weeks ago for some reason, I Googled Raspberry Pi regarding weather programs. 

My thought at the time was to get live local weather reports via the Pi. Also, it had been about 3 years since I had seen my Raspberry Pi and was not sure if I had thrown it out during one of my spur-of-the-moment clean-up binges. I eventually came across it after searching everywhere. "I put it where for sure I would know where it was". That did not work so well BUT I have learned that once I do find something I always place it back in the spot where I first looked for it. I degrees.....

My Pi

The box the Pi was in was complete with a power supply, protective case, HDMI cable, micro SD card and a cooling fan. I plugged in the Pi and powered it up with the micro SD card in place, a monitor, mouse and keyboard. Well a red LED light came on but that was it the monitor was blank, and well actually had a floating message "No device connected". I was sure I had downloaded a Pi OS onto the SD card years ago. I did a fast Google search and found out if you have only a red light and no green light (besides the red light) then most likely your SD is either blank, not in properly or defective. 

It was off to the Raspberry Pi site to download the latest and greatest OS and in my case that was bullseye. I did check the SD card and it was blank so I was hoping after the OS was installed and put back into the Pi things would come to life...and they did. I also found out that my Pi was a Pi3 (not Pi3B) the latest and greatest is the Pi4 B. The Pi3 will do me just fine and I am finally going to be using it. 

As stated I wanted to use it for local weather and I ended up finding something better! Local weather, space weather, UTC clock, contest calendar, VOCAP, a world map that has a host of configurations and more. The software is called HamClock by WB0OEW. This package runs very smoothly on my Pi3 and will auto-update, which I have experienced once already. 

And so it begins

Now Raspberry Pi is all new to me and I am learning about Sudo, the command line and what to enter into the command line. At this point, in time I have just cut and pasted commands from websites (such as HamClock) to install the program. The installation process for HamClock can be found under the "Desktop" tab on the HamClock site.
I am just starting my Pi learning curve and would appreciate any advice and program suggestions to run.

This coming weekend brings CLE 291. This is a challenge for all NDB hunters, both new and old and the ultimate test of your medium frequency receiving capabilities. Can you meet the challenge?

From CLE organizers comes the following info:

Hello all,

This coming weekend we have another chance to enjoy a Coordinated Listening Event. All CLE logs will be very welcome, short or long.

Days:                   Friday, 21^st April – Monday, 24^th April

Times:                 Start and end at midday, local time at the receiver

Searching for:    NDBs in the ranges

240.0 - 259.9 kHz   and   420.0 - 439.9 kHz

BOTH frequency ranges are for ALL listeners.

REU and RNA show that the number of NDBs, each

of them heard by at least 10 or more listeners in the

last 12 months, was:

240-259.9 kHz   420-439.9 kHz

REU                      30                         116

RNA                      54                         54

Please log the NDBs you can identify that are listed in the ranges, plus any UNIDs that you come across there.

You can find details, lists and maps of the beacons in those ranges, if you go to  https://rxx.classaxe.com/cle.

Send your final CLE log to  ndblist'at'groups.io  with “CLE291” and

“FINAL” in the email Subject.

Please show on EVERY LINE of your log:

  #   The full Date (or Day no.)  e.g. ‘2023-04-21’ (or just ‘21’)

         and UTC (the day changes at 00:00 UTC)

  #   kHz (the beacon's nominal published frequency if you know it)

  #   The Call Ident.

Other optional details - Location, Distance, etc. - go LATER in the same line (or in footnotes).  Please make your log useful to old and new members alike by ALWAYS including your own location (and 6-character Locator if you know it) and brief details of the equipment and aerial(s) that you were using.   

We will send an 'Any More Logs?' email at about 20:00 UTC on Tuesday evening so you can check that your log has been found OK.

To be included in the combined results  your log must have arrived by 09:00 UTC on Wednesday 26^th April at the very latest.

We hope to complete making the Combined Results within a day or two.

 Good listening

If you would like to try some remote listening - you could use any one remote receiver for your loggings, stating its location (and with the owner’s permission if required).

A remote listener may NOT also use another receiver, whether local or remote, to make more loggings for the same CLE.

CLE's provide several purposes. They:
