[Flexradio] PTT via CAT Port Problem

2009-08-14 Thread Ray Andrews, K9DUR
I am using N1MM Logger with PowerSDR and have bumped up against a problem
(maybe) in the way PowerSDR handles PTT via the serial port used for CAT.  I
am NOT talking about PTT via CAT command, but rather PTT via the RTS or DTR
lines.

I have the following serial port pairs set up in com0com:

COM7==Com17
COM8==COM18

PowerSDR is set up as follows:

Setup|CAT Control|CAT Control
   Enable CAT is checked
   Port is set to COM18
   Baud/Parity/Data/Stop settings are irrelevant. 

Setup|CAT Control|PTT Control
   Enable PTT is checked
   Port is set to COM17
   RTS is checked
   DTR is not checked

DSP|Keyer|Connections
   Primary is set to Radio
   Secondary is set to CAT
   PTT Line is set to RTS
   Key Line is set to DTR

N1MM is set to use the RTS line on COM8 for PTT and to use the DTR line for
sending CW.

If I am in CW mode, N1MM Logger keys the radio  sends CW properly.
However, if I am running RTTY or PSK31, N1MM does not key the radio.  I am
virtually certain that N1MM is toggling the RTS line on COM8, but have no
real way of proving it.

N1MM allows you to set up a second serial port just for PTT/CW control.  If
I set the 2nd port to COM7  tell N1MM to use RTS for PTT control and to use
DTR for CW keying, then N1MM keys the radio fine in RTTY  PSK31.

My question is:  Do the DSP|Keyer|Connections settings apply only if you are
in CW mode?  The FLEX-5000 manual states, This is useful as some programs
allow both CAT commands and COM port line keying for CW.  This says that
they will work for CW, but does not say whether they apply to other modes.

I wrote a simple utility that allows me to open COM8 and toggle the RTS 
DTR lines.  If PowerSDR is in CWL or CWU modes, then toggling DTR keys the
transmitter.  If PowerSDR is in any other mode, then toggling RTS and/or DTR
has no effect.  

Is PowerSDR working as designed, or is it a bug?  If a bug, I will enter a
Bug Report.  If not, I will enter a Feature Request.

[Flexradio] Equalizer

2009-08-14 Thread Everett B. Simonds
The Flex 5000A manual states that the balanced microphone input on the  
back of the rig does not have a 20dB preamp as it does for the front input.


Does the rear input bypass the PowerSDR equalizer as well?

Has anyone found it necessary to use an external mic preamp when using a  
PR781 on the balanced input?


Thanks.

Re: [Flexradio] Equalizer

2009-08-14 Thread Dudley Hurry

Everett,

If you have the internal equalizer turned on in the Transmit profile,  
moving from the front mic to the rear will only cause a slight loss in 
gain (overcome this by raising the Mic Gain)  so you should see much the 
same audio performance, just slight gain change moving from the front to 
the rear mic connector.

Re: [Flexradio] Equalizer

The TX EQ is performed in software and is enabled for all phone modes.  It is 
by passed for CW and DIGx modes.  The mic preamp on the front panel is a 
hardware preamp.

I have a PR-40.  I can drive the rig to full output with it using no preamp and 
the balanced line in on the back of the FLEX-5000.  I choose not to do this and 
use a mic preamp to provide additional headroom gain for the balanced line 
input.  So no it is not necessary.

Yes, you'll need a USB/Serial adapter to connect the Palstar to the

Re: [Flexradio] Operators Manual

2009-08-14 Thread Joe - AB1DO
Although the F3K manual does cover most of PowerSDR as appropriate for the 
F5K, I'm afraid there are differences, some more significant than others. 
For example, there is no antenna form for the F3K and the mixer forms are 
different. Also the F3K has no second receiver, cannot sample at 192kb/s, 
etc., etc.


Whether or not the manuals can or cannot be split in hardware/software will 
depend much on how the new architecture pans out. Right now there is a very 
strong relationship between much of PowerSDR and the hardware it is running. 
The trade-off will depend on maintaining a high degree of readibility and 
accessibility versus splitting the manuals software/hardware.

While we are on the subject of manual confusion (as opposed to automatic 
confusion), there is a little something that might not be very intuitive 
to new users (and some of us OTs too).


Even though the FLEX-3000 Owner's Manual indicates it is for the 
FLEX-3000, it actually contains the most up to date information regarding 
PowerSDR since it is based on v1.18.0 of PowerSDR as opposed to v1.14.0 of 
PowerSDR that the FLEX-5000 Owner's Manual is based on.  So those who have 
the FLEX-5000 (or SDR-1000 for that matter), if you want to reference the 
most up to date information regarding PowerSDR it is best to use the 
current FLEX-3000 Owner's manual.  Makes sense, doesn't it? :-)


I hope that there will be separate documentation for the software and 
hardware parts of the SDR system with the upcoming new software 
architecture code named Deep Impact.

Re: [Flexradio] Special Computer - New Idea: Benchmark

2009-08-14 Thread Gregory M. Zenger [N2GZ]
Benchmark idea presented at the bottom between stars (* *)

Lots of counterfeit capacitors out there. Some [mostly] Chinese companies
stole the formula for the electrolyte and started making their own
capacitors; of course they did it wrong (process, etc) and produced these
capacitors that have been plaguing a surprising percentage of products on
the market today.

The engineers who design products don't usually specify the brand; that is
left up to the company or division that is responsible for actually mass
producing the parts.  To cut costs and maximize profits, the cheapest parts
that meet the spec. are selected. These bad caps are often fine at first,
but after a few months or years of service, or so many hours of use, they
electrolyte breaks down and the tops bulge, the plates are distorted, and
the specification of the capacitor changes, often greatly.

What's unfortunate, is that different production runs or batches of the same
hardware part can end up with different brands of capacitors. So even in
Neil's computer, the motherboard, or power supply or any of the components,
could have bad capacitors, if they are not inspected before put into
service.

My friends and I have pulled from our university's trash, tons of
motherboards and power supplies and other equipment, measured the physical
sizes of all of the capacitors, and ordered replacements, a few hours with a
soldering station and we have working equipment again. All for a few dollars
spent at mouser or digikey.

Here is a list of some brands known to produce problematic capacitors.
http://www.badcaps.net/forum/showthread.php?t=388

If you are buying caps from mouser, digikey etc you will probably never
encounter these brands.


I think this whole 'special computer' thing is a bit overblown. Some good
points have been raised though.  The type of computer needed for SDR is not
that of your typical consumer PC. Best performance will not be achieved on a
machine with a million bells and whistles on the mother board, (turning
these off in the bios may help in some situations) A workstation type of
computer is probably more appropriate.  What about laptops? The Flex-3000 is
advertised to be a companion to a laptop computer. There are a lot less
options for laptops.


If the Flex will not work properly on the average modern (Dell, Gateway,
whatever) computer, then this is a problem that should be smoothed out by
the Flex/PowerSDR developers. I believe it is the goals and intentions of
Flex to produce a product that is compatible the majority of computers out
there. For those willing and able to spend extra, and get a Flex-C, or a
custom computer (build by themselves or some company willing to work with
them) then they can have a system that works a bit better than the off the
shelf alternatives that are more practical for many users.


*
What I think PowerSDR/Flex needs is a benchmark utility that measures the
parameters and performance of the sub-systems that matter. Things like
latency etc. come to mind. This way, Neil can build a computer, he has a way
of advertising the performance. Or I could build my own computer, and see
how well it works, do some tweaking, and see if I have changed things for
the better. I also could check to see if new drivers are affecting the
system. Or someone could buy a Dell, and do the same.  Using a benchmarking
utility we have a way to compare and share with each other what works. This
way we can make educated recommendations to help everyone settle on an
appropriate system that fits their needs, their budgets, and their shack. 
*

them both as the motherboards failed.  Up to about 1.5 years ago Dell

Page 47, I am trying to understand when the VFO B TX buton is yellow, what
does that mean?

 

Here's the explanation, which does not make any sense to me:

 

QUOTE

 

The operation of VFO B is similar to that of VFO A. However, VFO B is used
only in specific instances.

However, VFO B is used only in specific instances. When operating split
(SPLT button under VFO), VFO

B displays in red the transmit frequency (and TX indicator is red) When
activating the multi receive

function (MultiRX button under MultiRX), VFO B displays in yellow the second
receive channel's

frequency. Otherwise, it can be viewed as a storage container to copy VFO
data to (see the VFO

With MultiRX, the VFO B either IS or IS NOT the transmitting VFO.  TX on VFO
B is either gray (VFO A is transmit) or red (VFO B is transmit).  I
sometimes DO see TX as yellow, but I don't know how to make it occur and I
don't understand what it means.

 

Appreciate any clarification on this.  Thanks.
