OT - High Power?
Locked
 
|
What do you regard as “high power?” Is our beloved KPA500 at 500 watts a high power device? Or do you have to have a big Alpha at legal limit?

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. 73 de, --Ian Ian Kahn, KM4IK Roswell, GA EM74ua [hidden email] 10-10 #74624, North Georgia Chapter #2038 PODXS 070 #1962 K3# 281, P3 #688, KAT500 #860, KPA500 #1468 -----Original Message----- From: Elecraft [mailto:[hidden email]] On Behalf Of David Ahrendts Sent: Thursday, September 3, 2015 12:35 PM To: Elecraft List <[hidden email]> Subject: [Elecraft] OT - High Power?

For JT65 100 watts is QRO! ;-)

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... 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 9/3/2015 12:58 PM, Carl Jón Denbow wrote: > For JT65 100 watts is QRO! ;-) > > Sent from my iPhone > >> On Sep 3, 2015, at 9:39 AM, Ian - Ham <[hidden email]> wrote: >> >> David, it would depend on your context.

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. 73, Ed - KL7UW on 78-GHz 1w is super QRO.

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. 73 Bill AE6JV On 9/3/15 at 9:35 AM, [hidden email] (David Ahrendts) wrote: >What do you regard as “high power?” Is our beloved KPA500 >at 500 watts a high power device?

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

Gentlemen, thanks for your thoughts on High Power. We’ll now close this OT thread.

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. 73, Rick wa6nhc Tiny iPhone 5 keypad, typos are inevitable > On Sep 3, 2015, at 11:40 PM, Carl Jón Denbow <[hidden email]> wrote: > > Okay, I should have said 100 watts is QRO for JT65 on HF.
