I did a quick walk around informal signal check today with the Eton FR250 in hand.
Back at the greenhouse, I balanced the Talking House up in the corner of the greenhouse temporarily and draped the default wire antenna out through the eaves and did a slope antenna run to a sunflower plant carcass from last summer wrapped up in vines.
Went for a walk up my front street (heading north) which has some big trees along the way. The street is probably 15-18 feet wide I’d estimate. Street is fairly level in that direction.
as able to hear my TH broadcasting at around 2600-2900 feet before it went away midway across a viaduct (bridge). I stopped there and turned back. Possible the signal might have reappeared on the other side, but that’s a test for another day.
Tried walking a parallel street one block up and got nothing like that range there. Range seemed way less on street parallel. Looking at environment, it makes sense as to get signal that direction means overcoming the bricks.
So notes from this are:
1. The TH unit seems to function properly, at least with the wire antenna.
2. 2000 ft range seems doable and listenable outdoors.
3. Brick buildings seem to crush AM signals or at least cause deflection or other unwanted redirection.
4. The whip antenna hack connected to the internal ATU might not actually be as efficient (have to get the wire antenna vertically mounted on a piece of wood or in a piece of PVC to do a real comparison)
