I want to use a Collins 30L-1 amp with my K3, when I plug the 30L-1 amp control cable into the K3 KEY OUT jack, the 30L-1 keys. The 30L-1 is keyed by grounding it's key line (pulling -160 DC to ground). The K3 specs says +200 VDC, at 5 amps, I guess the K3 does not like the minus voltage on the 30L-1 key line, any suggestion other than an external relay?
