[Elecraft] KXPA100 with Other Radios

[Jose Rivera]

I am a happy KX3, KXPA100 owner.  I had the opportunity to obtain a Flex-1500 radio. I want to use the
Flex-1500 with the KXPA100, since the Flex is a qrp radio. 

My question: Do I have to have a cable running into the KXPA's PTT plug or can the KXPA100 be keyed up by
the Flex-1500 via just coax connections?

I am terrible making cables and soldering, which is why I am loath to attempt to make a cable. And no one
seems to sell such a cable. The Flex-1500 has a nine pin female DIN, While the KXPA100 has an RCA PTT.
