I have considered using a couple of short pieces of RG11 to get the
balanced line out of the shack. I don't think the additional resistance
would be that great, as the length would only be about 5 feet. However,
I'm sure there are some pretty high SWR points on the transmission line,

Chris,
The published loss spec for RG-11/U is 2dB/100' @ 100 MHz. This means that
at 100 MHz, the loss in a 5' run would be 0.1 dB. At frequencies below 30
MHz, the loss in a 5' run would be TOTALLY insignificant.

Hi Ray.
Thanks. I believe that spec would be for a 75 ohm impedance at both
ends. Since the impedance of the antenna would change considerably from
one frequency to another, that loss spec wouldn't work. Nevertheless, I
can't see that 5' of the cable would present much of a loss at any
impedanc

This is what programs like XLZIZL are for. Put the lengths of coax and
other components in, and see what the losses really are.
Gut feel.. 5 feet of anything won¹t make a big difference at HF.
Even if the VSWR is 20:1 (and the corresponding ISWR is the same) and you¹re

I recently built an Atom 330 Machine for the 5000A and ran into a
problem that I originally thought was a problem with the MOBO. If MixW
was in TX the power out would jump up 100+ watts output no matter what
the drive setting. The same for TUNE. This was even happening in LSB
(VAC disabled). The p
Mark,
Are you using a released or the trunk SVN version of PowerSDR and not any of
the new test SVNs on the Atom 330?
Are you testing the power output with an external peak reading power meter?
I am testing an ATOM 3300 (Intel mobo) too and I do not see this problem.
Also the behavior regardin
With high SWR the losses can easily be determined by TLW found on the CD
in the ARRL Antenna Book. The loss can be different depending on
whether the SWR is caused by a low resistance or a high resistance
because at HF the losss are largely IR due to the resistive part of the
load. At the sam
I never played with HotWheel before what a cool little applet
Now what we need is VFO A's freq read out in the PSDR button on the Start bar.
Then you can read your email and tune the band. That's what I really call
reading the mail. :)

Folks,
Due to a sudden family event, I will be away from the shack Sunday
afternoon, but if you are interested in the SDR radios from Flex

The Firewire hotfix may not be applicable. The Hotfix is for 1394b adapters,
which are the 800 Mbps adapters. The interface in the FLEX-5000 is a 1394a

the full data rate with WinXP and limits the 1394b adapter to a
I have attached an external; reference to a Flex 5000A. The reference output
is about 400 mv which is well within the input spec of the radio. The radio
does not appear to be locking onto the reference. when I check the external
reference box in the setup the radio's frequency shifts about 230 H
The PowerSDR sure could use a CW spot button. It would be quite helpful to me.

Even so, my SP3 install would not allow 5000A to work without this
patch. You mileage may vary.

You know Dave, I agree. We have had the code in DttSP to supporta

Don't let me forget.
