Geoff, yes you can use that point, and also connecting the chassis and body is a good way to go.
Does the radio tell you that it's tuning Ok ? If it does then there's no major earthing problem.
Radio Oz is a LOT more powerful than 737, and some nights you might not hear much of them, especially in Brizvagas.
For example, I am west of Toowoomba when I first start to hear the early morning skeds. Can't hear much of them on the mobile at home.
However, I can hear most of it on my base setup at the same place.
If you need more braid just strip the coax, makes an excellent earth braid for HF.
BTW any electronic rust prevention systems might bugger up HF receive, a fact lost on many.

Thanks for all that.
Yes, it said it was tuning ok. The radio says it gets a VSWR(?) of anything from 1.0:1.0 to about 1.6:1.0 when I was paying attention. Mostly it seemed to be about 1.2 or 1.3 : 1.0.
I planned to ask about the rust prevention systems (later). I read in the archives about somebody who had a megapulse (I think) and it seemed to be interfering with the radio. I don't have electronic antirust at present. But would like to add it. I guess I'll need a kill-switch or some such for when I want to use the radio.
So I take it the further bush I go the better reception will get. Is that because it just happens to be better for atmospheric bounce, or is it because there is lots of "noise" in cities? Kinda makes it hard to be sure it is all working before I go though. We're off to the Simpson in three weeks.

Geoff, less interference in the bush, and a number of other tech factors.
You could try selcalling a mate to see how your radio works, but be sure to choose the right channel for that distance and time of day. Or you could try a
beacon call to one of the bases (same rules as above).
Try using the radio (receive) with and without you being mobile. From memory the later Barretts have an excellent noise reduction system.
Good luck with it.
