I have a B line and a TR4. I use a shure 450 mic on the B line and the audio is
rich and not tinny. I have a D104 on my TR4 and it has a 750K resistor in
series with the audio line to reduce the highs. Yet, it is more high pitched
and I use that advantage for working DX, I work the mic close.. not 3 inches
away, I use enough mic gain to deflect the plate current meter. around 11
o'clock. Pay attention to the 12AX7 mic amplifier tube. Replace it if
necessary, or sub it with the other 12AX7. Try to get on the Drake net on
Sunday at 2000Z at 7138 so our technical people can hear your audio. Also, Make
sure that your tranceive alignment is on. if it is wrong, your PTO could be
transmitting higher freq than your receive. I hope some of this helps. 73's al

Well I am working on the audio now!!! I have only owned these shortly and I
absolutely love the receiver audio and the way it all operates. If anyone else
knows how they are supposed to sound, it would be a real plus!!

Hello
This is often the case with drakes their audio is tinny sounding . Mine are
the same way R4B - T4XB. If anyone knows of a way to custom tailor or pad the
audio to let a few lows through I'd like to hear it.
I have had this discussion before with a few guys and they thought that
carrier balance could be off or the filters are not where they should be or
component values have changed over the years. If that is the case I would not
really know how to attack the problem .
Maybe someone who had a Drake new back in the day could tell the group if this
is just normal comm. audio..

Hello to all,
Just purchased a beautiful set of drake twins, r4 and t4x, they are an
absolute joy to operate. My only problem is with the
tx audio. I get reports of it being very trebly (if thats a word). I am using
a shure 444 with it. Hope to enjoy these rigs for a long time. I sold a ts 2000
to purchase them and I am glad I did. Love the vintage tube stuff!!
Tnx
