First thing I recommend id to run a good ground braid from the powersupply  
to the radio. I have solved several weird problems with this..

good luck

And good filtering.  Old, dried out electrolytic capacitors can have 
lower than rated effective  capacitance, for a while, before they cause a 
more catastrophic  failure.

If it is a filtering problem  due to not enough capacitance in the power 
supply, the peak voltage may  stay the same and the 120 Hz ripple will 
get worse during higher current  loading on transmit. Depending upon what 
kind of voltmeter you use, you  might not see this as much of a voltage 
drop. An oscilloscope would be a  better way to see if this is the 
problem. Or just replace the filter  capacitor(s) and see if the problem 
goes away.

Need to balance the transmit and receive audio on LSB and USB, right now my
LSB is great full sound on transmit and receive, but on USB both transmit and
receive are squeaky narrow, can someone tell me if there is a pot on the
radio to adjust this and where it is located. 73.

Hi Don,

If there is a significant difference in the audio, comparing LSB and 
USB, the most likely reason is that the BFO frequencies for LSB and USB 
are not adjusted properly. The Omni VI manual lists the correct 
frequencies as 9.000000 MHz for LSB and 9.003000 MHz for USB. There is 
an order in which the adjustments should be made, which is important, 
because there are several trimmer capacitors and two crystals in the 
BFO. Some of the capacitors are in the circuit all the time and some are 
switched in by diodes only for some modes. If you do it in the wrong 
order, you'll probably never get it right.

The 2.4 kHz wide 9 MHz IF filter in the Omni should cover the frequency 
range of 9.000300 to 9.002700 MHz. When in LSB with the BFO running at 
9.000000 MHz the low end roll off due to the filter is at 300 Hz. In USB 
with the BFO running at 9.003000 MHz the low end roll off is also 300 
Hz. Based on your description of the problem, I would say that your BFO 
is running a frequency higher than 9.003000 MHz on USB. If it were 
running at 9.003300 MHz, the low end roll off would be at 600 Hz instead 
of 300 Hz. You would have less low end audio response.

By the way if you look at those numbers you'll realize that in the 9MHz 
IF, when you are in LSB mode, the radio is generating and receiving USB 
at 9 MHz. And  in USB it operates on 9.003 MHz LSB. It gets flipped over 
when it is mixed with the LO.

If the BFO frequencies are correct, the other possible cause of the 
problem is some non-symetrical filter shape which might be caused by a 
poor solder joint or a bad crystal in the 2.4 kHz BW 9 MHz IF filter. 
This is much less likely than improperly adjusted BFO frequencies.

Could anyone give me a comparison between the Delta II and the Paragon II
.Which one is considered better than the other and your opinions why .I own a
nice Delta II but I would like to try something new and I,m considering the
Paragon II .Is it worth the difference in cost ? The Delta II average about
$500 to $600 and the Paragon II,s seem to average about $700 to $1000
depending on the options such as filters .Thanks David N4XCE

Perhaps foolishly, a month ago I shipped two as new Titan II (Model 416) 
shipping containers to KB9YOZ upon receipt of his email agreement to 
reimburse the postage costs....while not a lot of money ($22 bucks), it is 
the principle of the matter.  I am hoping that he  has not followed through 
for good reason but his failure to reply to my emails has me wondering.  Not 
what you think of when you think of Ten Tec users.
Has anyone else had any dealings with KB9YOZ? Thanks for any info...
Tony, W4FOA

Tony -

Sorry to hear this, but...?  Hope you do get reimbursed for your kindness. 
Still miss you in
the club, OM.
