Howard:

Now that I use a Tentech 238A manual tuner all the time, I agree with you 
totally.

I think the auto tuner in the TS480 is good for basic functional purposes, 
but I think my Tentech manual tuner wins hands down, both in terms of 
receive noise, and in terms of matching what I have available for antennas.

I don't have an explanation for the difference you suggest, but I really do 
agree with you that the difference is there.

Subject: ts480 test


I don't trust my observation, so I'd like somebody else to test it.  After a
day of experimentation, I think that using my ts480 with an external tuner,
provides a better signal to noise ratio after tuning the antenna, than does
bypassing the external tuner and using the internal tuner.  I don't use the
internal tuner on receive.
I'd like an observation and an explanation.  Seems surprising to me.
