A very-common, no-tune RX antenna is the Tilted Terminated Folded Dipole
(T2FD). And if the termination is built to handle enough power, it can be
used for transmit too. Here is a good construction article for one.

Maybe the best antenna solution is a very large discone antenna like the one
at the old missile site near Tucson, AZ.  Unity gain but very large
bandwidth.

I have an M2 7&10-30LP8 log periodic up at 120 feet that will do wonders as

http://www.m2inc.com/pdf_manuals/7%20&%2010-30LP8.pdf

It covers 40M-10M very well and makes an interesting "monitor" antenna on 6

inoperative while PJ6D was in on 6 last summer and I couldn't quite make the

[Flexradio] v/u & Satellites

[Richard Lawn]

I'd like to hear from users that have the V/U module installed that are
using it in the satellites. Is it necessary to have the 2nd rcvr installed
to operate full duplex? What tracking software are you using and have you
found any glitches. I'm trying to decide on the upgrade and whether to fund
it by selling my FT-847 or TS-2000.

Thanks in advance for any advice.

Jack,This very question has been troubling me.  SInce the radio will receive 
all frequencies, and display 8 slices of them, how do you engineer an 
antenna with gain across all frequencies, and/or gain in eight directions? 
(Since the 6700 has two antenna paths for its eight slices, you'd really 
only need to engineer gain in four directions, and or on four frequencies). 
Is the answer a no-gain vertical, or long wire?  Or external antenna 
switches into the two RF paths?
I can just imagine my SteppIR trying to adjust length for four slices at 
once: it'd be better than watching a trombone concert.

A diagram of the hardware innards will certainly be helpful.But I 
think

some diagrams showing how the new hardware might be used within an overall
station would be even better.

For example,  the ability to receive (and presumably transmit where legal)
over the DC-to-daylight spectrum is technically very cool.   But what kind
of antenna system is connected to that port so that an operator can take
advantage of the power of an SCU? How does a station use the typical
limited-bandwidth ham antennas,  antenna tuners,  etc.?

What kind of operating activities might that operator be doing at the
time?

E. G.,  what might my station look like if I want to work a multi-mode
contest on 40/20/15 bands while I also monitor WWV and 6M?   People do 
this

kind of stuff now with multiple radios and multiple antennas.   How will
the new Flex fit into such a picture?

The new hardware is very cool.   But it's unclear how you might use it in 
a

real station configuration to take advantage of the capabilities.   Some
concrete examples would help a lot.

Re: [Flexradio] Flex-6500 antenna port (s)

[Len Morris]

It would seem to me that the SteppIR will only track the TX freq, which there 
will only be one freq. The other slices will get what the Rx antenna will 
cover, and slices out of the antenna gain range will be down.. The slice that 
is tracking the Tx will be fine.. 
Is that too simple of an explanation?
That is how I see my 6500 working when I get it.

Mathias,The standard method to troubleshoot. when all else fails: Reset the 
database to factory defaults.  If that fixes the problem, then an option was 
inadvertantly set incorrectly, or a PC crash hurt the file. If the radio works 
again, then you can import the tables with Ray K9DUR SDRDataTransfer.  Or, you 
can re-enter the options manually.

[Flexradio] PJ4 Operation.

[Dr. William J. Schmidt, II]

Well I've been on the air here (PJ4 land) for about 24 hours and I continue
to have some lock-up problems (every 15 minutes or so).  I even shut down
N1MM (just using the logging part).  I think the problem now is I can't get
a good ground anywhere.  The CPU is running about 10% loaded.

Re: [Flexradio] Flex-6500 antenna port (s)

[Jack Haverty]

A diagram of the hardware innards will certainly be helpful.But I think
some diagrams showing how the new hardware might be used within an overall
station would be even better.

For example,  the ability to receive (and presumably transmit where legal)
over the DC-to-daylight spectrum is technically very cool.   But what kind
of antenna system is connected to that port so that an operator can take
advantage of the power of an SCU? How does a station use the typical
limited-bandwidth ham antennas,  antenna tuners,  etc.?

What kind of operating activities might that operator be doing at the
time?

E. G.,  what might my station look like if I want to work a multi-mode
contest on 40/20/15 bands while I also monitor WWV and 6M?   People do this
kind of stuff now with multiple radios and multiple antennas.   How will
the new Flex fit into such a picture?

The new hardware is very cool.   But it's unclear how you might use it in a
real station configuration to take advantage of the capabilities.   Some
concrete examples would help a lot.

Re: [Flexradio] FLEX-1500 no more working

[Mathias Krüger]

Hello,
i never used the squelch before, but if it is swiched on squelch is
working. I have it off normaly. It is not the problem.
Thanks for the hint.  But i have to look for another reason.

Many of the high-end RF switch companies sell some very nice blocking RF
switch matrices that meet these requirements.  They'll set you back quite a
few $, though ;-)

For a less pricey alternative, take a look here:


http://www.microwavejournal.com/articles/1615-matrix-switches-blocking-versus-non-blocking

then acquire the appropriate surplus multi-port mechanical coaxial switches
off of eBay, etc., and homebrew the beast.

Let's say you wanted a 4x8 matrix.  You would need:

4 8-port switches (RX-side) ...can't find any 8-port? Use 2x 4-ports
and a Transfer switch configured as a self-terminating SPDT (corner common
and a termination on the opposite corner)
8 4-port switches (Antenna-side)
32   short low-loss coaxial cables w/ connectors to match the switches (you
might want to have these made new - or DIY)
1 control mechanism of your choice
Nappropriate DC power supplies (go linear here to keep the RF noise
down)

Ta-Daaa ... you have a matrix that can connect any one of the 4 RX-side
ports to any one of the 8 antenna-side ports simultaneously, with the sole
exception being that a single Antenna-side port can only feed one RX-side
port at a time, and vice-versa.  Insertion loss at HF/VHF will be very low
in the switches, with the dominating factor being the interconnecting
cables.  Isolation will be 80 dB or better (I've measured in excess of 100
dB at HF/VHF).

If you want more ports on either side, just follow the general example
above accordingly.  If you plan on running TX power through the matrix,
then look up the power handling capability for the particular switch model
numbers you have.  I've been able to find data online for switches just by
doing Google searches with the exact part number - even when they haven't
been made for several years.

I've used this sort of matrix in complex engineering characterization test
systems for years and they can be quite versatile for routing signals in
both directions to where you need them.

Oh... and if you decide to try this with solid-state switches, the
insertion losses will be greater and the power handling capability will
generally be much lower.

[Flexradio] preamp on 3000

[y...@aol.com]

 was there a sn# on the 3000's that would show the rig had the preamp upgrade 
from the factory? If a older 3000 went back to flex to be upgraded, anyone have 
a guess on the cost and was the upgrade worthit?
thanks

Re: [Flexradio] flex pepole please read

[Sheldon Hartling]

There should only be two command lines.

To fix the word-wrap in the original post:
The first command starts with "rename" and there is a space between
"Default" and "2012"
The second command starts with "copy" and there is a space between "Default"
and "2012" and between "FlexRadio" and "Systems".

You can move the Flex Radio logo from the top-right corner of the display to
the bottom-right corner by opening a command window and entering these two
commands:

rename "%appdata%\FlexRadio Systems\PowerSDR\Skins\Default
2012\Console\picDisplay.png" "WAS_picDisplay.png"
copy "%appdata%\FlexRadio Systems\PowerSDR\Skins\Default
2011\Console\picDisplay.png" "%appdata%\FlexRadio
Systems\PowerSDR\Skins\Default 2012\Console\picDisplay.png"

This will "remove" the logo from a dual display like the panafall.

You can edit the background skins in mspaint. I don't recall where they were, 
but it didn't take long to find them and the edits only took a couple minutes.
