[Elecraft] KPA1500 with P3 Transmit Monitor

[Clay Autery]

Whether the TXMON add-on to the P3 "should be [useable] with the 
KPA1500" is certainly an opinion you may choose to adopt.
Whether Elecraft wants to implement your desire for lifetime forward 
compatibility of all existing products with all future products is a 
decision for the company, not us.

Frankly, I think that would be financially unwise and a severe 
limitation on engineering and innovation.

If YOU want to use your TXMON features on YOUR KPA1500, here is how you 
do it...

Bypass the KPA1500's internal tuner.  Add your OWN external tuner 
between the antenna and the KPA1500....  Insert your TXMON module 
between the tuner and the amp....  (or any other place you may care to 
insert it).

This is the path I am choosing to take, as I will always have horizontal 
loop(s) that I want to use on multiple bands and frequently need better 
than a 3:1 tuner.
When Wayne asked the pre-launch question, "What features...", I 
specifically asked for NO on-board tuner knowing I would never use it. 
I'd MUCH prefer an external KAT-1500 that can tune full power to 
10:1.... cost be d$%^d.  :)

Alternatively, you could perhaps figure out where to tap the signal path 
and pull it external to put your module inline... or simply trust the 
numbers being computed by the device itself.

Cleanest idea for no external tuner would be to add the SWR/power 
readings to Win4K3Suite...

Just my 2/100ths of a US Dollar...
