power pole reverse voltage indicator
I took one of the power pole voltmeters and hooked it up with reverse polarity. It drew no current, and it worked fine afterwards with correct polarity.
If a power pole circuit was hooked up backwards, the volt meter would be off. One might think that there was no voltage present.
So, I added a red LED, with current limiting resistor, to the voltmeter so that the LED would turn on if the polarity was reversed.
Attached is a photo with it hooked up with reverse polarity.

Re: Costco portable generator
All this being said... I have one of those Firman generators, same as the one pictured.? Came with the camper I bought last summer, brand new in the box.? I have used it once.? Have not used it for anything radio related.? If anyone wants to know...I can fire it up and see how much RF interfeance it does or does not cause.? And I would sell it for $300.? Don't need it as I have a Honda.
I might weigh in and mention that I have two Yamaha generators (2800 watt and 2000 watt) and feel that they are comparable to Honda.? My most recent Yamaha is the 2000 watt similar to the Honda.? Same pricing, size, convenience, weight
and spec¡¯s, and I went back and forth between the two brands before buying.? I finally chose Yamaha because it has a fuel tank shutoff valve on the control panel.? I turn that off and let the engine run dry for travel (less gas smell in an enclosed vehicle
or trailer) and in the fall I turn off the fuel valve, let the engine run dry, and just put Stable in the fuel tank for storage. Starts right up in the spring, and I have been very pleased with it.? Before the Yamahas I had a $350 Homelite and it was hard
to start, ?was always having carb problems, and ran rough whenever I could get it started.? I gave it away when it started gushing fuel from somewhere deep inside.? ?Honda or Yamaha are the most reliable and guaranteed to run when they are needed, and it might
come down to whether your favorite color is red or blue.? Jim, WA7MKN

The other thing to consider is how clean the power output is. I do all the training for Murdoch's staff, including on generators. A LOT of the cheap generators put out power
that would trash your laptop if you ran it regularly on that power source. I'd imagine the same is true for radios. You
absolutely get what you pay for in generators. In seven years and many many vendors, I've never seen a single exception to that rule.

Looks like the ham $35 fee won't start until summer... Here is a copy of an email I received:
Contrary to what you may have heard or read, the collection of
application fees for the amateur radio service and certain other
services will NOT begin on April 19, 2021.
Although April 19, 2021 is the date the rules in the FCC Report and
Order adopted last December generally take effect ¨C i.e., one month
after the R&O was published in the March 19, 2021 Federal Register ¨C
certain parts of those rules, including collection of the application
fees for the amateur radio service, will NOT begin on that date.
The effective date for new amateur radio fees has not yet been
established. The FCC explicitly states in the published Notice that the
fees will not take effect until:
? ? ?*? the requisite notice has been provided to Congress; AND
? ? ?*? the FCC¡¯s information technology systems and internal
procedures have been updated; AND
? ? ?*? the Commission publishes [FUTURE] notice(s) in the Federal
Register announcing the effective date of such rules.
The League¡¯s counsel for FCC matters estimates that the effective
start date for collecting the fees will be some time this summer, but
regardless of the exact timing we will have advance notice. Stay tuned
for further developments on this.?
Keep in mind that one can only renew their amateur license within 90
days in advance of the expiration date. If you, or a club station
license you are trustee for, are within that 90 day window now, I'd
renew as soon as possible to avoid the new fee.
If you are thinking of switching to a vanity callsign, I'd also
seriously suggest you apply for that special callsign sooner rather than
later.? (Of course, if you are an Extra class seeking a new shorter 1X2
or 2X1 callsign, competition for those calls in the future MIGHT be a
bit less due to the new fees! We'll see...)

Re: Link to Bob Bruninga's Presentation
Hi Rob - he is an amazing man.? The reason that we scheduled as we did was because he is undergoing chemo for one week and then double the next week and then resting a week.? We did this nearer to the end of his rest week to help give him time to recover.? Like I said it was longer than I expected but a lot of information and a extremely energetic person.? Besides all of this he is a very fine man.? Hope you enjoyed his presentation. Ronnie

There will be a hidden transmitter hunt Saturday March 13th.
3 transmitters on 144.525 MHz, starting at about 9:30 AM.
Will monitor the 447.70- (77hz) repeater when I can.
De-Briefing at the DPS Electronics parking lot, 317 Gallatin Park Drive.
Chose Saturday, because DST starts Sunday. Dark mornings again...
