Good morning!!!!

Got Tractor Morning Drew,

did you know there is a radio free area in West Virginia.
Scott sure won't be saying hello to anyone there for sure.

Absolutely fascinating Drew, actually that was a test question on my Amateur Extra exam, but I honestly didn’t know all the specifics Thankyou, the way life used to be

Good Tractor Morning Steve,

Scott Yes added to the decent antennas it did and best of all the Radio I run @25w and Amp puts out about 250w so the radio is just Loafing along.

Actually you answered my question before I even asked it So it appears that you can adjust your amplifier output by varying your input.
So I have one OCF dipole where the balun can only run at no more than 300 watts. My other OCF dipole 40 thru 10 can take 3000 watts. So I guess my only problem is to remember which antenna I’m using before turning on the amp
It also sounds like you can push that amp up to 600 or 700 watts.
Wondering what your experience is with that ?
I have been blessed with being on a hill, up around 560 ft above sea level and I have both dipoles up about 60 ft, so I am getting out fairly well already. I think I would use the extra power for working DX and any contests I might enter

So it appears that you can adjust your amplifier output by varying your input.

How important is noise factor or noise power in your application? If you can vary the input without attenuators (i.e. resistors), then that's a good way to go. But if you're using something like a variable attenuator anywhere upstream of the amplifier, then you're gaining up all the noise it creates, and really hurting your noise power.

If you look inside most variable-gain amps, you'll find they will often use the gain control to drive a variable attenuator(s), but they will place these as far downstream as possible to minimize this problem. The limitation in how far you can push that concept is the power rating of the attenuators, most of which are 1 watt or less.

The other option is usually varying the bias to the transistors in one or more stages of the amplifier, but this is substantially more complicated, and comes with other penalties (higher harmonic distortion, etc.).

<-- spent most of a career designing RF and microwave amplifiers, 50 MHz to 18 GHz and up to 100,000 watts CW power.

If Ziggy's, then good. If Keystone Volvo, just run away!

I spent many years dealing with both, although I'd have trouble believing Ziggy is still alive today.

We loved our Volvo's but had to stop buying them, because our local dealerships were that bad at everything. What a shame, they're great cars.

strange, I bought three volvos over thirty years from keystone, never had an issue.
244DL sedan, 740 turbo wagon, recently an XC60 off lease.
but then none of mine got higher mileage where the big stuff kicks in.
no I'm going to this place:

I started out with foreign cars in 1967, bought an
absolutely cherry beige peugeot 403 sedan for a few hundred dollars.
With a four on the tree, a sunroof and reclining seats.
drove it for a month til I figured out it had a fourth gear...
And solid rims that had to be done with old fashioned tools.
Shucks Garage in Stockton helped me, Dick Shuck was the local guy here.
I went off to college and had to sell it, no cars for freshmen and I couldn't afford it anyway.
A car was for me to get to work. In college I walked...

the metal on that 403 reminded me of my father's 55 Chevy. Felt like it was a quarter inch thick.
Like the old Checker cabs. I think it only had 70hp or similar, but very fun to drive.
Those reclining seats almost got me in big trouble. Almost...

Zigmunt Motors still in Doylestown.

Good Tractor Morning,

In plain English: What did they do ??

Jim, my question also

Lou, hope pain isn’t bad, and a quick recovery for you Sir

Good Tractor Morning WinterDeere,

How important is noise factor or noise power in your application

My concern with noise is on the receiving end of my station if I am understanding you correctly. When I turn on my equipment, if the noise level is really high I just turn everything back off again. Although my Icom IC7610 can dig out a signal that is at noise level. But for pure operating enjoyment I hate listening to all of that.

28 outside right now, snowing. Expecting an inch or less. Ground has slight cover to it already and I hear the emergency vehicles in the distance. Already.

Hope all have a great day. Be safe, stay warm.

Off to the morning chores and stoking the wood stove.

 

[DarkBlack]

It’s a balmy 2F here now, predicted high today of 23F.
The whole next week is forecasted to be cold with some mornings going negative.
Going through some firewood

Good Tractor Morning,
Ct, 8 F to start, and it looks like it won’t make it out of the 20’s.

Another busy day delivering yesterday. I think I delivered somewhere in the neighborhood of 3400 gallons. Delivered to one fuel assistance customer, $800 K home with a sports car in the garage and an entire landscaping crew cleaning all the yard leaves, and they were allotted 265 gallons of Free fuel oil . I absolutely hate scammers, Donny know how they do it, but it’s a shame that this happens

Looks like mostly an inside day with these temps

Hope all have a great day

Good morning TBN!!
36 here this morning and rain. Will probably end by lunch time but it won't warm up much.

Mostly ran around yesterday doing errands. Got the tractor wheel fixed but haven't put it back on yet. Probably later today when rain stops.
Came home and just relaxed,
No agenda today yet except putting the wheel back on.

Time for a second cup
Everybody have a great and safe day!!
