Awww, come on, Lyle. That makes too much sense.  Management will never understand that logic.

Since 9.8kW ERP is plenty, why not 9.0, or 8.45 (half of 16.9)?  The difference from 9.8 won't be noticeable, the transmitter won't be pushed to the limit, and you're not spending more on antenna, bigger transmssion line, etc.

It's a new station, no license yet, we're sizing everything now, we could
run up to 16.9KW but thinking that 9.8 KW will be plenty. To do that we'd
need to run the 5.5KW.

IF Nautel says it will do 5500W, then it should be fine, a transmitter
isn’t a car, in other words, a transmitter runs at a set power level 100%
of the time, it’s not stopping at red lights, or going up or down hills……so
if the manufacturer says it will do 5500W, it would be used at 5500W full
time.



That said my inclination would be to go to the next bigger transmitter,
which I think is a 7.5. That way When an RF module fails, you stand a
better chance of making (closer to) licensed power while it gets repaired.


Now the better question is, what is your licensed ERP, how much and what
size transmission line, type of antenna, and any filters. In other words
Have you calculated how much transmitter you need? This statement makes me
wonder “Management wants to run it a full output for a max ERP.” Because
MAX ERP is your LISCENSED ERP.

As long as you have a good load, proper cooling and aren't exceeding your
licensed ERP...you should be fine at 5500 watts.

We're looking into getting a new Nautel 5KW transmitter. They are rated
for a max output of 5500 watts. Management wants to run it a full output
for a max ERP. Is that something you have done? or would even consider?

To me, it feels like I'm gonna get in my car and run full throttle 100% of
the time! Don't think it would last too long at that rate.
