I suppose if you're an expert at everything, there's no reason to try to help. 1G requires all four pair. If you're getting a good 1G connection, your pairs are electrically connected. If you have th

My Trane makes a lot of noise. I added their "fix" but I think I probably need to make sure it's properly grounded. The bigger problem is that my furnace is a hybrid, meaning that when it gets too co

Lots of RFI from my Trane HE hybrid, even with the factory rfi choke installed. No RFI from my Carrier High Efficiency Hybrid gas / air heat pump (reversible air conditioner). 73 & DX, Gary - AB9M Sa

I'm not a lawyer, but part 15.103(d) appears to exempt furnaces. If possible, when you replace your HVAC system, have the company doing the install write into the contract both you and they sign, tha

Obviously, you are not a lawyer either. I would not mention things that have no applicability to the issue or you're going to get arguments that they are compliant with Part 15, and now that you've m

I haven't actually confirmed this completely, but I think my MFJ detector picks up a lot of RF that is above ultrasonic. Pointing it at a fluourescent fixture picks up a lot of buzz. I bought it as a

The Trane kit didn't do much for me. You can google for it to see what is in the kit . If I remember correctly, it was just an RF filter on the power line. Want to recall Trane hvac systems have a rf

It has analog controls. It washes very well. It is has a great reliability record. It is pricey for what it is, though. Wouldn't trade it for any other make or model. Dennis AE6C And none from ours,

OK. I just tried 20M and didn't have any issues. 40M was my problem last night. I'm not sure of what the equipment nomenclature is. I have two units, fiber-to-copper, and then a router following it.

Nice work! I've lost steam now that I'm just using FT8 and don't have to listen to the radio. I'm also in the middle of town and have given up on tracking down noisy houses. I tended to use MFJ equip

Thanks for the tip. I don't mind modifying/repairing MFJ equipment. I'm a ham after all and even worked in a ham radio repair shop where I developed my wariness of all things Swan. :) You may have to

I would not assume that people understand this is a joke. It's been suggested many times on here and old timers talk about it, so I understood that it used to be standard (and rather foolish) practic
