Modern troubles again
#5

I made another interesting discovery while taking notes on this radio yesterday. Last weekend, it was noted that the high impedance antenna connection was not providing very good sensitivity on the short wire I was using. It ought to have been the best option. The antenna terminals - spring clips and an SO-239 socket are attached to a small PCB. This assembly should also have a 9:1 impedance transformer, but mine doesn't. It is clear that the component was never soldered in to place, as the traces are still bare copper!

So, another task will be to attempt to make and fit a suitable transformer.

I don't hold with furniture that talks.
