Re: Spitfire Am Transmitter Hum (Buzz)
Hi all again.
I think a possibility presents itself - I can run a piece of coax from the aerial socket of the Spitfire to a little distance outside the building and then hang the aerial from a tree and it's not too hummy. The Spitfire still needs to be earthed near the device - and even then any mains leads coming anywhere near it introduce a lot of hum in the modulation. But at least I have a workaround which I am happier with then running everything outside.
I wonder why this device is so sensitive to hum relative to the SSTRAN. Hmm.
Thanks all.
Kind regards.
From Mike.
