Yes, it's now restored & working to the same level as I remember way back in the 90s when I had one on my belt in addition to a satchel type strap over the opposite shoulder.
I live on quite high ground & could hear somebody around 30 miles away tonight, in addition to strong local stations.
The power is spot on 0.4w/4W absolutely level throughout the band, and audio is great.
At some point in the next week when it's dark, I'll nip out with it & see how it performs.
To conclude - I'm eternally grateful to you, techman, & other's that have been so kind as to be patient with my layman terminology & assist with this peculiar fault.
