There is something I have observed on my Tram D201 over the years and never thought about till now. There seams to be a sweet spot on the TTC control, as it gets close to the one o’clock position
Modulated power out is much better. I have always attributed this to audio circuit liking the higher frequencies being passed. Has anyone also noticed this (Sweet spot)?

Marc I haven't noticed a 1 O'clock sweet spot per-se, but I do notice that overall mic gain seems to increase along with the frequency of the TTC. I just attribute that to the TTC attenuating the high frequencies when the TTC is turned CCW, and thereby reducing the overall gain at those frequencies. |

Sandbagger I think I may have read your post wrong, but in my thinking the way you have the explanation for Treble and Bass settings on the TTC control is backwards. For more Bass in your voice it should be set CCW....for more Treble in your voice you would turn it CW, at least that's how my Trams are. If I misunderstood your post, I'm sorry for trying to correct it. Marc Sandbagger is correct when he said that the higher you set the TTC to the Treble side, the more it sure does appear to drive the radio more. I noticed that years ago when I bought my first Tram. But like Sandbagger, I don't really see any particular sweet spot except when the treble is increased darn near to it's max. I've kept mine at around 11 o-clock since it was new. It really would depend on the operators voice and microphone. Sniper |

Sniper There really isn't a bass boost per-se, but rather when the TTC is turned CCW, it is reducing (attenuating) the high frequencies, which make the bassier frequencies appear stronger in relative comparison. When the TTC is turned fully CW, the full range of frequencies is allowed to pass, which increases the overall gain, but the treble tones are more pronounced, especially with an already high end emphasized mic like a D104. It's a totally different story when paired up with a Turner Super Sidekick. In that case the TTC sounds better in the CW position. With a D104, I tend to run mine around 10 O'Clock. |

I understand now Sandbagger what you are saying. I run my stock D104's with my Trams, and right at about 11 o-clock on the the 2 D201's. I did try my Heil HM-10, and I tried it with the 4 and 5 elements. Everyone said that in the 4 position it sounded very close to my D104. With all honestly, I still think my Tram has the best receive audio of anything I own including my Ft-102 and Ft-1000D. Maybe after all these years I'm just used to listening to the sound of the Tram and just can't get accustomed to the other radios receiver tone. Anyways, thanks for the insight Sandbagger. Sniper

That is the same direction I was coming from The radio responce to the higher frequency's is better.
Now I have been playing with getting the circuit to pass more low freq so that when the TTC is rotated CW the percentage of lows that are cut are less and the highs still remain the same, and a better balance is achieved.
