Some try to develop scenarios that justify enabling transmit

I recently received a Yaesu FTL-7011 F radio. It's brand new in the box.
It has 24 channels and operates form 485-512 Mhz.
Can anyone think of a use for this thing ?

I must agree that the CK1614 is an extremely versatile timer, with many
potential uses. However, using it for fan control is not only expensive,
but unnecessary.
A fan blowing on a transmitter heat sink does absolutely nothing immediately

I agree that timers for fans are a waste of time, effort and money.
If you can stand a little waste of power, I like to simply key the fan with
a relay driven by PTT. Sure, it starts the fan before it's needed, but to me
it's no big deal. Once the repeater stops transmitting, so does the source

This is excellent Eric. I have an R1225 repeater in a GR500 case. There is a
fan but it runs continuously. The duty cycle is low but because of the
nature of
the service there are times when it may be very high for extended periods of

So most of the time the fan is not needed, but I want it

Larry,
That's odd; both the GR1225 and RKR1225 repeaters I am familiar with, which
use the R1225 transceiver, have a small thermal switch that is wedged
between two of the heat-sink fins. In both repeaters, the fan runs only
when the radio gets hot. I am surprised that you have a repeater using
