Re: NaP3 Setup for Panadapter and Waterfall Display from QRP-Labs QMX/QMX+ Transceiver
Joy, I have seen a video of Hans playing his favorite rock band using the QMX+ in SSB mode. This radio uses a similar architecture as KX2&3 use. It has lots of great features for a great price. I you like to wind toroids, it is a great kit. Otherwise, pay an extra $60 to get it built and tested. Happy Thanksgiving, Dave W6VYC

Pipe sizes
Some while back, there was a discussion about pipe sizes. For example, does ?” specify the ID or OD?? In the 21st century the correct answer is neither. Starting in the early 1700’s steam engines were being developed.? They needed pipes for steam and water.? Different shops started making pipes and fittings and valves. ? Then the steam engine people wanted higher pressures which meant thicker walls.? If the OD was kept the same, fittings and valves did not need to be re-tooled.? So the “next generation” of 1 inch pipe might have an ID smaller than 1 inch. ? From time to time, improvements in metallurgy and processing allowed thinner walls and cost reduction so the ID might be bigger than 1”. And every shop had it’s own specific sizes.? Why would they want to share the business with a competitor? In the 1920’s standards committees published “schedules”.? “1/2 inch” refers to a schedule (or table) of dimensions.? PVC pipe commonly comes in Schedule 40 and Schedule 80.? Both have an OD of 0.840.? The ID is 0.602 for Sch 40 and 0.526 for Sch 80.?? I suspect that, “40” and “80” might be echos of terms originally meant for 40 or 80 psi steam. There are different schedules for copper pipes and stainless steel pipes and ... Anyway if you are thinking about a project, it is best to look up the schedule of dimensions to know what size wooden dowels and U-bolts you will need.? And you can blame this situation of a committee. More history here:?? and here:? Be sure to scroll down to see all the messages in this thread. |
A Powerful Gift!
Free to a good home is a vintage Knight Kit P-2 SWR/power meter. These are simple and rugged units with many uses, 5.0/5 rating on eHam. This particular P-2 has the interesting characteristic of being hyper-sensitive. When passing 5W to a dummy load, I had to turn the sensitivity control almost all the way CCW (i.e., min sensitivity) for full-scale power meter deflection on the Forward setting. Another P-2 that I own required nearly full-CW rotation (i.e., max sensitivity) for FS reading on Forward under same condx. If I connect the gift P-2 "backwards," i.e., transmitter to antenna port and vice-versa (forward / reverse paths are symmetrical), sensitivity appears normal. Wiring appears correct and the knobs are new.?
?
Could make an interesting project or could be a "feature" for QRP ops! Any takers? Best, --David KM6RI

Re: QRPops Zoom meeting tomorrow 11:45-1:45 for those interested
开云体育Howard, thanks for hosting!? we had a rollickin' great time.?
folks that missed, I hope we'll have another rainy Friday some
time soon.? here's links to a few things we discussed: tonight John Portune W6NBC is talking about slot antennas at
FARS.? From Steve K6OIK: "This
meeting will be simulcast on Zoom.? Connection information will
be posted on FARS web site shortly before the meeting at ."
730pm meeting starts. Dave W6VYC showed a new book, intro and survey of SDR.? I missed
the book title and author.?? Ah, there it is
Also showed his Hermes rig, including the software running on a
Raspberry Pi 4.? I think the software is HPSDR
Dave KM6RI talked about his new W6xxx? loop antenna.? And high
QRM at QTH.? everyone agreed Dave should set up the loop and use
it, to find the noise source and null it out. I'm looking forward to zooming in to the FARS meeting presentation.? slot azntennas offer a lot of physical configuration possibilities.? Cliff K6CLS

Re: Friday
I just returned from Chester today, hitting a hole in the "bomb cyclone."? Two and a half weeks where the wx was so bad I couldn't even put up a hamstick.? After my driveway was plowed at 7:30am this morning, I left at 8am and drove in driving rain for 3.5 hours before outrunning the storm.??

Re: New DX entity
Monsieur Pollack, actually Napoleon made one more trip to his final resting place,? a tomb underneath the rotonda of the Invalides, the Military Museum of France,? located in Paris.? I know this because I visited it in person several years ago.

Excellent tidbit about the dx entity.? Thanks for sharing.?

Re: OT - if you are looking for a cheap but great trip
开云体育Joy,Even though English is not spoken widely in Japan, many mono-lingual American visitors have enjoyed traveling to Japan.? It’s probably the safest country in the world to visit. There is no reason to hesitate. You’d have a blast. I’d be happy to give you pointers. Also, ask Dave Pollack about his experience of visiting Japan as an American.
