Seems to me the upper power limit in those days was 1,000 watts, but I probably remember it incorrectly. I'm not sure when, but it changed from 1500 Watts input to 1,000 Watts output. 1,000 Watts is a lot of power and may not be of much use, depending upon what you want to do with it. The difference between 100 watts and 1,000 is not very much when the band is open and not crowded, in a contest it may be the difference between making contacts and getting lost in the pileup. You mentioned you were in the hills of California, if you want something that is (almost) 100% reliable for an emergency a satellite phone might be better. In another thread in an another group, I mentioned the ELT (emergency locator transmitters) that at one time were sold only for airplanes being available for hikers, etc. The original poster said they are now down to around $100 each, which makes them a viable option for your car if you think you may end up in a ditch with no cell phone coverage and out of the range of any radios. Welcome back, btw, you can ask for your old call if it has not be taken by someone else. 73, Geoff. -- Geoffrey S.

You mentioned you were in the hills of California, if you want something that is (almost) 100% reliable for an emergency a satellite phone might be better. I used to have one about ten years ago, when a bunch of us motorcycle riders commonly cruised the scenic mountains here in northern California, again well beyond cell-phone range. If one of us bikers got in trouble, it was my job to call in a chopper. Beware, OT Rant Coming Up ***************** My 'cycle license is still valid, but now I have enough sense to avoid motorcycles. g For 7 years, I worked as a motorcycle messinger in the Los Angeles area, never had an accident, except for one time. An older gentleman edged onto the freeway from an on-ramp, going about 20 mph, cutting across all lanes into the fast lane, where I was going the "legal L.A. speed limit" of about 85 mph, along with all the other idiots. I _almost_ managed to keep the bike upright, but not quite - - - dumped the bike at the last minute with my leg trapped underneath the heavy bike while it was sliding to a stop. Last I saw of the old gentleman, he was still chugging away in the fast lane at 20 mph. g I was lucky, a trucker behind me swung his rig broadside to block the fast lane, until the ambulance arrived to scrape me off the freeway. Like with a horse, you have to get right back on again. I was back on the job in a few months, but very careful to avoid older car drivers. What really bothers me is that the youngsters today do not properly train themselves to ride a motorcycle. I traded in a new heavy Honda "Valkyrie" model, for an even heavier Honda "Gold Wing" model, the murdercycle that has a reverse gear, because it is too heavy to back up by using your feet, if you are on a slight downgrade. A youngster bought my "Valkyrie" from the dealer I sold it to. Youngster promptly killed himself a few weeks later, when he lost control of the Valkyrie on a turn. I really think the laws should be changed, to force the youngsters to take the $50 3-day course from the MSF. (Motorcycle Safety Foundation) MSF will not authorize a motorcycle license unless the youngster demonstrates competence by passing some rather stiff riding tests. End of OT Rant - ********* Welcome back, btw... Thanks very much, I should have returned to ham radio long before now, as it is a great endeavor, in my opinion. My daddy introduced it to me when I was about ten years old, it lead to a 34 year career in electronics, working in the research labs of what then was called Hughes Aircraft, later to be called Hughes Aerospace. Many interesting projects during my career, such as working on the old robot series of spacecraft named "Surveyor", paving the way for manned spaceflight to the moon. Back to beating the bushes, the enjoyable task of deciding which shiny new rig to purchase ![]() Mark |

I'm not sure when, but it changed from 1500 Watts input to 1,000 Watts output. The current limit on most bands is 1500 watts, Peak Envelope Power (which is an output-power measurement). It has been quite a while since the limit was specified in terms of input power to the final amplifier. 1,000 Watts is a lot of power and may not be of much use, depending upon what you want to do with it. The difference between 100 watts and 1,000 is not very much when the band is open and not crowded, in a contest it may be the difference between making contacts and getting lost in the pileup.
