The OP never came back to this thread, but there is something very wrong if a simple dipole does not improve on just the connector.

Well, sure someone somewhere developed some stereo FM tuner better than my SAE3200. And ... I don't like the digital way that much, sorry. So I'm forced to analog MONO. It's good enough for my night listenings. Many thanks.
The blend switch is available on some tuners to reduce some of the stereo noise, which essentially merges the L+R at higher frequencies.
On Brian's site (http://ham-radio.com/k6sti/) he shows some modifications to the basic circuit.
The old TCA4500A/LM4500AN part has a analog blend input control, that uses the analog signal strength output from the usual quad detector, ( CA3089/HA1137 etc) to control the blend or separation.
Modern day DSP parts like Si4735 do the same blending, but in a much more sophisticated way using controlable (registers) for filter and thresholds settings. I designed/built a DSP radio/media player using this part based on the Elektor article now 10 years ago 🙂
The two protype radios sit on the shelf, collecting dust, how many tuners do I need?
But in the end the highest quality signal is required to get the highest quality sound, back to having the best antenna you can have in your situation, mine is climbing up on the two story roof, yagi ... the wife looking up at me, shaking her head, be careful up there, just to get my favourite LPFM station, with comercial free broadcasting ... Today I listen using a old Sherwood s-7650cp that I have fixed up for my cousin as a favor ... Fun wow
