[Amps] keyers heath HD-1410, ham keyer HK5A

[Dan <n5ar@air-pipe.com>]

I picked up these 2 keyers at a ham sale. They seem to work OK, however, 
the outputs are obviously not a simple open circuit/short circuit like a 
relay. I assume they are some sort of transistor switch. I would like to 
know what sort of voltage/current ratings each output has. I assume they 
are suitable for keying a modern tranceiver. Can anyone help?
