Hello
Sitting in the back yard away from the house using just the
telescopic whip antennas the older Grundig G5 whupped the newer G3 in
AM reception. Medium wave AM G5 was more sensitive.
Shortwave too, 15 mhz time signal not audible on G3 was heard faintly
on G5.
Anyone else notice this?

Similar reports on eham.net. Some suggest sample to sample variation
due to poor quality control on early G3's.
