Re: [Elecraft] OT - High Power?

[Rick Bates]

Folks are missing the point. 

If producing even a weak signal at the other end requires maximum legal power, 
so be it.  It's still a weak signal. 

QRO is a mindset, not a fixed level.

Okay, I should have said 100 watts is QRO for JT65 on HF.  I've never used it 
on VHF, UHF, EME, etc.  I know it was developed for EME, but it has evolved a 
lot since then.  The newer JT9 was developed, as I understand it, for 
terrestrial weak signal use.  Perhaps my original meaning would have been 
clearer if I had used that mode in my example.  73 de Carl, N8VZ

Re: [Elecraft] OT - High Power?

[Bill Frantz]

I can go to 100W with my K3. That is what I currently log as 
"high power" in RUMlog. There are many K3 options that are 
higher on my wish list than more power.

Re: [Elecraft] OT - High Power?

[Ian - Ham]

David, it would depend on your context. For typical, day-to-day operations, I 
would say anything over 200 watts is high power. Most contests recognize high 
power as anything over 150 watts. If you are a QRPer, anything over 5/10 watts 
(CW/SSB) is considered high power.

Personally, if I have my KPA500 on and am using it, I consider myself running 
at high power, even if I'm only getting 300-350 watts out.

Re: [Elecraft] OT - High Power?

[Bob]

High Power is like beauty it is in the eye of the beholder.

Being an OT'er anything beyond the basic 807 or pair of 6146's is High Power,   
So my KPA500 is surely such.


My backup station which is a K2 driving a legal limit Ten Tec Titan sits 
unused.  Hard to beat the integration in the complete "K Line". However if a P5 
operation becomes available the KPA500 may go on a temporary hiatus.  I'd do a 
station reconfiguration until that is in the log.   In that pileup the legal 
limit might be low power, Hi Hi...

Re: [Elecraft] OT - High Power?

[Edward R Cole]

Jim beat me to saying it:

Depends on what band, what application you are talking about.

JT65 was created for weak-signal eme (originally) ...and where I use 
it 1000w is QRO and 600w is not.
QRP must be used in context of what is being attempted...I ran 150w 
on 2m-eme and that is considered QRPp.


On eme RF power is not very accurate description; ERP more relevant 
(eme doesn't happen without certain amount of antenna gain).  My QRPp 
ERP was = 150w x 83* = 12,450w, *19.2 dBd ant gain = x83


Currently I run 1300w, and ERP = 1300 x83 = 107.9 kW
wouldn't you like to run that on 20m!

JT65HF is a "johnny come lately" mode.  But there are a whole suite 
of digital modes available for experimentation by all aspects of ham 
radio - just be careful with sweeping statements without stating 
their application.
