[GreenKeys] OT: remote transceiver

[E.]

In my situation, I could only put my antenna in one place and my station at almost the total opposite side of the basement in the house… no choice - it’s the layout of my house :/ … so I just ended up running almost 100ft of LMR 400 from the station (along the rafters in the basement), out to the antenna… hardly any loss.  Then the next thing - the power mains inlet is halfway around the corner of the house, so grounding was an issue… so I just ran the grounding wire on the surface outside, from the mast and first grounding rod, to the power mains.  I put plastic cable protection tubing around the ground wire to partway protect it above ground because I mean, if the first ground rod doesn’t take care of the bolt, then ground wire buried a foot down won’t make that much of a difference either.  Arcing could be an issue I suppose, but again, in my situation, I couldn’t really bury as well :/ .  I really do need a second ground rod… was the plan in the first place… but need to redo something in order to redo something in the first place -- clear as mud, right ;p ?

Not a easy run for the bond wire either.

Yeah, some fancy transceivers allow control over an internet connection, but those seem to mostly be thousands of dollars and/or are hf rigs (I just want 2m/70cm).  I have multiple cat6 cables available between the locations, and solid wifi with three access points, but these products all seem to get pricey.

>> What about mobile rigs with separate faceplates (must have mic input on faceplate also)?  I have no experience with them, but the price is reasonable (even adding a dc power supply).  Of course they are designed for 10 or 15 feet separation in a vehicle, but can any of them run further?  Do any brands lend themselves to a hackable interface to drive a long cable?  If it is just mic/speaker analog or digital signals, and some digital control channel, that would be easy enough to wrap with a bit of circuitry at each end.  Don't even care about what the proprietary digital encoding is, as it would just need a cable driver that handles the rate/slew/levels.
