Cheating? Yay or Nay?

What say you?

I have a very good Ham friend who is in a dilemma.

He is a senior Ham, and a few years ago, he moved into his daughter and son-in-law's house after his wife passed away. He's always been active, having great stations and decent antennas when he had his own house. Not wishing to be a bother or an imposition, he has made a lot of sacrifices and compromises.

He's always had verticals, wires and even a tower and a yagi when the house was his and his wife's. However, now he has resorted to a GADS antenna - gutters and downspouts. That's not his problem. In fact, he's been quite pleased with that setup as it has allowed him to do a lot. He gets his share of DX and  stateside contacts, as well as ragchews.

The problem is the solar panel system that his daughter and son-in-law have installed on their roof. So much RFI is generated that he can only operate on 40 Meters and below. Starting at 20 Meters, there is so much garbage generated at regular intervals across the bands as to make them useless.

He's tried contacting the solar panel company, but as you might expect, they don't seem to be anxious to help, even though that's required by law. About a month ago, the problem disappeared and my friend was estatic. The letdown came a few weeks later when his daughter informed him that there was something wrong. Their provider wasn't giving them their discount for the electricity being pumped back into the system by the panels. They called the installer who rectified the situation, only to re-introduce the dreaded QRN that my friend thought was gone forever.

So I made a suggestion that he should use his laptop and use a webSDR receiver as his receiver. He'll still transmit like always, but for 20 Meters and higher he'd rely on receiving through an SDR receiver that is in his area. It's not 3 or 4 states away, it's local as far as radio is concerned.

He told me that he had thought of that, but as a Ham licensed for over 50 years, it feels like 'cheating" to him. It's not like he's contesting or anything, or trying to get a leg up on anyone else. I told him it's a matter of survival. And in this case, getting on the air this way isn't nefarious or under handed in any shape, way or form.

So what say you? Let me know what you think by posting a comment. My friend is a regular reader and I'd think he'd appreciate some opinions other than mine.

Another pleasant surprise

Two weeks ago I was walking past the steps leading to the basement, and I noticed that ol' familiar electrical burning smell. Not overpowering, without any visible smoke, but enough to set off the alarm bells in this Ham's cranium.

I went downstairs to find the smell emanating from our clothes dryer. The top was very hot and the smell became even stronger after I shut it off and opened the dryer door. Fearing a lint trap fire, I gave the lint duct a touch with the back of my hand to see if that was warm. Compared to the dryer itself, it was stone cold. I went outside to the vent opening on the house and gave a good sniff. Nothing from that end either.

Convinced and relieved that the house was not in danger, I unplugged both the washer and the dryer and let them sit. The dryer cooled off. I wasn't sure what the exact cause was, but I suspect that the control circuit board had gone again, as it did a few years back. The odor was identical to that of either burnt components or traces on a circuit board.

The matching washer had been giving us its own problems for over a year now. I decided that it was time to purchase a new pair.  My wife didn't object to my statement that I didn't want a fire hazard in our house.

We went to Lowes, one of the big box hardware stores where Marianne picked out a pair of machines manufactured by Samsung. I was a little wary. Our cellphones and TV are from Samsung, but our washer and dryers have always been Whirlpool, Maytag or even GE going back to my parent's house.

They were delivered a week ago; and as Marianne seems happy with them, I didn't give much more thought to them - until yesterday.  I was downstairs listening to not much on 20 Meters, when Marianne came down to put in a load of laundry. I was about to answer a lone CQ from UA3EDQ when I thought to myself, "Here we go!"

Our last pair of washer and dryer were notorious RF generators. If I was on the radio and Marianne put in a load of wash, I could literally hear the agitator motor in my earbuds. I could heard the motor rev up and die down during the spin cycle. The dryer wasn't as bad, but was still a nuisance.

To my delight and surprise the Samsung pair are the antithesis! I was able to work Igor without having to listen through RF hash. Both the washer and dryer are RF silent on 20 Meters. I checked the other bands as well, and they all seem to be free from washer and dryer hash.

So kudos to Samsung! Whatever and however these machines were engineered, they seem to be Amateur Radio friendly!
