SRF-M37W curiosity


Steve KT5H
 

When I awoke this morning, there were way too many lightning crashes
on the MW band here, so I tuned to the weather band to listen to the
forecast.

In doing so, I noticed that the battery indicator showed full capacity
while on the MW band, but upon switching to either of the FM bands or
weather band, it fell to one bar.

Has anyone else experienced this with their M37W?

Do you know the cause?

Does the FM circuitry require substantially more current than the MW
circuitry, thus the battery indicator reflects that difference?

Just one of those things that make you go "hmmm..."

72 es gud dx,
Steve

I have one in the mail.... That will be interesting to check out with a meter.

I own several M37V/W receivers and there is no change in the battery indicator switching from AM to FM bands. 
 
Good DX.

Thanks, Richard.

I took another look at it last night.

This time, there was no change between MW & FM, but the indicator dropped from 3 segments to 1 segment when I switched to weather band.

When I switched back to MW, it came back up to 3 segments and remained there.

Curious.

I have two m37W and there is no change in the battery indicator switching between AM/FM/WX on either unit.
