Hmm - apparently not - RS website finds nothing here either :-(


You managed to find the only website with a 100% negative rating on
the G5! :-)


I have one (Eton G5). Essentially, I agree with those comments. LW
insensitive, and suffers from MW interference. MW is OK. SW not bad from
(say) 4 to 20MHz (not good at all 1.6 to 3MHz, where whip switches in).
FM seems very good (don't have really local stations, so haven't noticed
overload). Where insensitive, external antenna helps, but overloads
easily.

So, Ian - the whip is not the antenna for 1.6 to 3 MHz? If so, I
assume it relies on the internal ferrite, which would typically be
inadequate...I have an older single-conversion superhet analog radio
where the ferrite works all the way to 6 MHz - to increase
sensitivity, I place a *single* wrap of normal wire around the radio,
connected to my external antennae. That brings up the signals a lot.
More than one wrap of wire and I get images galore...so my experience
matches yours closely.

I think the lesson here is that:

(1) It's hard to get good reception on a portable on the 1.6-3/4 MHz
band; and

(2) you need a rock solid front end to be able to use an antenna for
1.6 to 3/4 MHz and NOT get spurious junk, unless you are far away from
major MW transmitters.

Yes. It uses the ferrite rod up to 2.999MHz. At 3MHz, you can hear the
noise increase, but the sensitivity is poor up to at least 4MHz. The
external antenna connection (via 3.5mm audio jack) seems to work on all
frequencies. There is a 10dB attenuate to help with overload (a tuneable
passive preselector would help a lot).

I forgot to mention that it's full of self-generated internal beats
(nothing to do with the incoming signals). A few of them paralysingly
strong, especially when you're using the whip.

All-in-all, it's not too bad a little portable radio, but it certainly
is not a serious communications receiver.
