Does your wireless Powertap work properly when riding on

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

1. A trainer (e.g., Kurt Kinetic Road Machine);
2. Rollers; and /or
3. Rollers with magnetic resistance unit?

I assumed he was more worried about electromagnetic interference from the magnetic trainers. Could be wrong though. The amount of wattage being dissipated through a magnetic trainer could cause a large enough magnetic field to interfere with wireless communications. Especially weak ones such as the short distance ones from Powertap to computer. Plus the distance from magnetic field to the powertap is quite small.

really depends on the frequency of magnetic radiation the resistance unit is giving off. I doubt it's the same band, stranger things have happened though.

If my cordless phone rings, it kicks me off my wireless internet.

OHHhhhhhh...I use a leather brake....I don't know the answer on that....

if that were the case, you could run a passive antenna...solid copper wire from the back end area of the hub
to the front of the unit, [length in even multiples of 31.25mm ] it could help
