Not in the real world. The REAL limits on serial cable are 1) capacitance and 2) noise pickup. If you use low capacitance cable, and if the cable has good noise rejection, you can go hundreds of feet

At my old QTH in Chicago, I had very limited space for antennas. On 160 and 80 meters, I used a long wire that ended in the shack and ran within 18 inches of the serial cable connecting the computer

shielding Most "RF in the shack" has a "Pin 1 problem" as the root cause. I haven't looked at the Orion, but my Omni V has a pin 1 problem. My FT1000MP (which drives a Titan 425) has a pin 1 problem

That's my solution also. It's very easy to wire them to the Herc II, and it works fine. You need the right Molex connector (easy to buy from Newark, Allied, Digikey, etc. Two 50A supplies is pretty c

If you connect it properly and don't overdrive it, the Herc II will work well with any decent transceiver driving it. I've successfully used mine with an Omni V, K2, K2/100, TS850, and FT1000MP. You
