High Power Ham Radio Stations - Your Responsibility 

OK Jim! You'll be fine :)

Wow, thank you

0.1 k-Banana! :)

Thumpy!

Why is that..? They TX 2.7kHz wide. That's it. Doesn't matter what power you are running. Now - if your receiver is as wide a barn door, then you ought to fix it.

If you run more power his filters will have to be in good order.. I was under 10 miles from your 1kw live stream tx and either side of center was clean enough... I could hear you on a 3inch wood screw on my rx input though.. For most of my tx I run radio power and enjoy myself just fine.. Antenna Antenna Antenna Then amp..

@DXCommanderHQ used to seeing people from Europe splattering over the bands - just thinking ahead of how it might be when they're in the next street :) When I'm doing some ft8 and the guy a few blocks away comes on, it's game over for me on that band - can't really filter that out easily?

Sunds like fun! Watch this space!

Fascinating.

@@DXCommanderHQ That was just an fyl for comparison. I know if very few people with amps that large here. Maybe a couple that hang out on 160M but that's about it.

What amateur amps can run that kind of power, the big Henries?

If you're on 10 meters, here's a hint: if the solar flux is below 160 100 watt DX is nearly impossible. If it goes above 170 the world is your oyster. I use 100 watts and a Penetrator at 25 feet.

I had PLENTY of 100W stations last night. They aren't rolling over.

@@DXCommanderHQ Heck, I talked with VK2BY with a TS-430S and the Penetrator from Pittsburgh last night about an hour after my sunset. I turned the radio on and there he was, so I threw out my call and was surprised when he came back.

Haha.. OK Ade.. I remember having to reboot the fridge!

If you want to find out what RF can do run power. There are things you can do with a 4 watt CB radio but it gets more interesting the farther upscale you go. Let's start with your CB. You can interfere with analog television. Usually making the picture fuzzy and coming through the sound. You can come through the landline telephone if someone is using it. You can be heard on record and tape players. You can come over commercial public address systems if you're close enough. Let's put a 100 watt linear on. Everything above gets worse. You will not only blank out your TV but those of you neighbors. You will start coming through their phones and stereos. If you are in an apartment and using an indoor antenna, picking up a spoon while you're transmitting becomes a shocking experience. Been there, done that. So, we earn our ham license, and go for the maximum amount of power output. Expect to come through phones, TVs, table radios, and all sorts of things even though they are turned off and unplugged! Fluorescent lights will illuminate as if by magic. Family members may be shocked when operating faucets and shower controls. Microprocessor controlled equipment like HVAC systems, washer/dryer, dishwasher, and the refrigerator may stall and stop working. Garage door opener may operate on its own. People wearing jewelry may experience minor burns. Home security systems will begin sending false alarms. The way to avoid this carnage is to mount the antenna as high and as far from any houses as possible.

Welcome!

Yes Arndt! And from wikipedia: On 27 June 1817, the British member of Parliament William Lamb proclaimed that "the possession of great power necessarily implies great responsibility"

Yes!

Jim, drop me a line and I can build something for you!!

Yes.. I remember a Russian station a few years ago, he was literally end-stopping my meter.. Calling CQ CONTEST.. I hit him with everything I had. Totally deaf..! He must have been doing 20kW. Not joking.

Unfortunately it happens all the time on all bands :(

Ah!!

You had an RF powered electric water heater. Good that the amp did not arc something. 73, Jim W6LG

One way of heating up the coffee!

Our radio club inherited a Dentron 2meter amp. We were running a Stationmaster on the 146.61 repeater. It was fine at 100 watts but not at 1500. The higher you go with power the smaller the window of error becomes.

@@spaceflight1019 you've got that right! Did you hurt the repeater?

@@NovemberOneOscarGrouch It caused the amplifier to fail, long after everyone had gone home. After the second failure we abandoned the amp. We would encounter the problem of the GE Master 2 110 watt repeater amps failing and the "cure" was to replace the antenna. Once we abandoned the Stationmaster and went to a four pole the issue went away.

Wow

Sounds like corona discharge. 73, Jim W6LG

@@ham-radio yes ! Cal gives instructions on his antenna's to prevent this off the end of wire on his antenna's . things change at KW RF power levels . 73's

Thanks, you too!

Acom Director (don't use latest version but one before). I also use ARCP 990, N1MM and Camdesk.

Good point!

Antennas work exactly the same on tx as rx unless you meaning high tx power is causing the antenna to break down..

Currently EcoFlex 15.. SImilar to Messi & Paoloni's heavy stuff - but I already had it knocking about.

Interesting.. How do you find a call from a name..? OK, there is a book, it used to be published annually, it's called the Call Book.. Not sure if you can reverse search from a name to a callsign.. Perhaps drop the RSGB a line - even Ofcom. If you have an address and a name, someone might be able to find it. Fun fact: You MIGHT be able to take over that call if / when you pass your ticket! There's some motivation for you!

Thank Cal for the reply, will drop them a line, I hadn't thought about taking over his call sign, that'd be really good. I love radio, and do a fair bit of shortwave listening, wife rolls her eyes when i put up yet another long wire lol, going to find out when our local amateur radio meet and start popping along. Love the channel 73's

​God bless your grandad ♥️ he would be so proud of you

Acom 2000 is comfortable with up to 575W of reflected. Nothing wrong with it.

Totally agree with you ground control, you want minimum reflected power in this hobby. Even if producing 1kw there should be no more than 5 watts of reflected power. You always want the best of matches concerning VSWR, reflected power, and of course antenna tuning. 73’s

I have a few, verticals and dipoles

Send it! LOL

Difficult if you want DX on 40m. But everything is possible, depends on how much patience you have.

@@DXCommanderHQ Yes, VK3YE does well on the beach. Location, location, location? Not sure how I'll do here as I've been inactive for 8 years 160 to 20m due to internet QRM of S8. It cleared up when they went to fibre optic cable in January. 73, Bill, G4GHB.

Haha

I see pink elephants, but hey..

I genuinely don't understand about the QRM issue. If the bandwidth is set correctly, you shouldn't splatter. END OF.

I hear U.S.A. stations 5.9.+20dB. Not surprising, 1.5 kW, 5 el Yagi, 100' tower. I'm glad I don't pay their electricity bill. How loud do they need to be? Recently my 5 Watts got me Sicily at 5.5. report, 1400 miles on 17m on my attic dipole. Readabilty 5 is what matters. G4GHB.

Anyone who knows radio can relate to this...

Nooooo!

Yes!
