Hi All
Would like to use the SDR for serious contesting. So far have been unable
to resolve several issues. Normally run SO2R at high power using a FT-100
MK-V and and IC781 plus amps. The station is adequate to achieve rates of
70 to 80 per hour under good conditions. Use FSK with MMTTY with N1MM or
WRITELOG software. Station is stable with minimum RFI in the shack and
only
problem is second harmonic of 40 meters de-sensing the 20 meter radio for
a
portion of the 20 meter RTTY band (+- 10 kHz from 2x the 40 meter freq.).
However:
Using VAC:
DIGL PTT drops out too fast and loses parts of messages
ZERO beat moves the rtty mark signal to the center of the filter band and
not to 2125 Hz. ditto for mouse click .
Using any external program ( MMTTY or N1MM) with PTT by radio command
causes the the SDR-1K to immediately go into receive before transmitting
of
of the letters still in the pipeline.
On the other hand: It takes 2.4 seconds to go into xmit before it sends
out data.
This is independent of audio buffer or DSP size from 512 to 2048 VAC
buffer
held at 256
as an example, buffer contains (including spaces:
{TX}CQ TEST DE NO2T NO2T{ENTER} {RX}
What get received (FT 1KMK-V) is:
(transmitter on)__ CQ TEST DE NO2T NO(transmitter off)noise noise etc.
The underlines representing carrier without diddles or any modulation.
Changing the VAC delay to 10 ms/int maybe causes startup time of 2.03
seconds between keying and data. Shut down is immediate with loss of last
few letters.
Without VAC and using an AUREAL AUDIO sound card everything works well--
but not enough power output with the audio gain at maximum. Delta-44 shows
-35 db on it's WAVE OUT 3/4 display. Using VAC gives all the output
needed
to drive the external amplifiers.
I have tried to fix some of the problems:
POWER 1.6.0 (Modified SOURCE CODE AND COMPILED so that DIGL uses CW mouse
click)
Freq readout on diplay for DIGL is off 2 kHz from mark freq. The same is
true in the N1MM bandmap when used in the same computer using VCOM to
provide the interconnection.
BUT!!!:
The frequency sent to a "real" ComPort and to another radio is correct!
By "REAL" is meant the frequency shown is the MARK freqeuncy. This is
commonaly used to define the location of a RTTY signal.
Where in the code is the calculation for putting the DIGL mouse click to
20xx Hz?
Where in the code is the ZeroBeat for DIGL determined?
Where in the code is the Frequency diplayed determined?

You guys nailed it as a battery charger. I had previously turned

You do not want to know how many times I have looked for a hardware
problem or software glitch and it was an unplugged cable. One day I
pulled most of the 3 remaining hairs on my head out when I could not
figure out the high swr (on my Steppir antenna which was perfect with my
conventional rigs) and poor power on my amplifier. I whined and
complained and then asked myself how many races could I run a month on
one hours food. I had it on a 12 amp supply.
Glad it is working.

Hi Jerry,
There are several of us that prefer REAL FSK for RTTY. Truth is the SDR
lacks some in that department. I have done some work on the receive side
of
the console to enable RTTY to the correct frequencies for 170 shift FSK
reception (-2295 -2210 -2125). All the filters are optimized for RTTY when
in the DIGL mode. Click tuning works correctly which is really cool.
The setup form has some new controls for selecting FSK or AFSK so as not
tie
up DIGL if you don't want FSK. You are on your own for FSK xmit for the
time
being as SDR is not implemented yet. Quiet a bit more to doing the xmit
side. But, you can use AFSK in MMTTY or any other package. This is a work
in
progress and there is a lot left to do to get it to where it should be,
but
it's a start.
Looks like you can compile the code so if you are interested in what I
have
done let me know and I will put the code on SVN and talk you through it
either on the phone or TeamSpeak.
73,
Steve - K5FR

The Flex Meetings will be at the Crown Plaza at 7 p.m. on Saturday May 20.
Again, this year, I will be MC, (can't figgre out why, but probably cuz I
wore a tie last year!) More information will be forthcoming. Everyone is
welcome! I'd really like to meet the presidents of YIK there!
John - W5GI mentioned it in an earlier message.
For the new owners, and participants of this Reflector, John also
mentioned
"Flexi awards" which is an honor that FlexRadio Systems awards to the
Flexers who have made most significant contributions to FlexRadio in the
past year. One award is given for contributors to the Software, and one
for
support called "Goodwill Ambassador". There may be one given for hardware
support and ideas, however, that is has not been determined.
The forum last year, and this year is informal (my 10 year cycle of
wearing
a tie notwithstanding). Just a fun time for Flexers to gather, and enjoy!
Emotional expressions of Boo'ing and Hissing and Cheering wildly and
Laughing are permitted. Quiet clapping is frowned upon!

I am sure all of you are aware of the issue with the Firebox related to
the substantial roll off of the noise floor starting at 24 KHz when
operating at a sampling rate of 96 KHz. If not, you can refer to the
follow up post by Eric on 3/30/09 entitled "Panadapter at 96K
Questions".
Essentially, the noise floor past 24 KHz rolls off significantly. Eric
assumed it was an anti-alias filter of some sort, which was a valid
assumption. Starting on 3/30/06, I tried contacting Presonus Tech
Support via e-mails and phone calls that went to voice mail. None of
these went answered. Finally after calling numerous times I finally got
through to a live human being.
I'll have to admit the Tech Support guy I talked to was very interested
in the anomaly I was describing. He was so intrigued that he went and
discussed it with one of the main software developers. The answer I
received was interesting to say the least. The developer admitted that
this behavior has been observed and is a known bug in the Firebox
firmware. The same bug existed in the Firepod firmware and was
subsequently fixed. It has not been fixed in the Firebox. The reason
he gave for not having a fix for it yet is that not enough people have
complained about it since most people who use the Firebox use it for
audio recording and not much is recorded above 24 KHz. He also
indicated that it would not be trivial to upgrade the firmware once
fixed ($$$). The unit would have to be returned to the factory for that
change. I assume that the firmware is read only and probably soldered
to the PC board.
So, it looks like we need to band together as a disgruntled user base
and mount a letter (e-mail) writing campaign to request that the
firmware be fixed so that we get the attention of Presonus and put this
issue on their radar. It should be a polite correspondence indicating
the problem, the fact that it is a known issue and that you would really
appreciate them making an effort to fix this in a timely manner. If
they get inundated with requests, it should expose the problem.
Here are the folks at Presonus that this effort should make an impact by
reading you letters. I am sending my letter to all of them.

Where in the code is the calculation for putting the DIGL mouse
click to
20xx Hz?
[Eric] Look for the picDisplay_MouseDown() routine. Note that all of
these functions are in console.cs.
Where in the code is the ZeroBeat for DIGL determined?
[Eric] ZeroBeat is called from the zero beat button. See the
btnZeroBeat_Click() routine.
Where in the code is the Frequency diplayed determined?
[Eric] The frequency calculations can be found in the
txtVFOAFreq_LostFocus() routine.

Welcome to the wild and woolly world of using devices with A/Ds outside
their nominal intended uses. The same problem exists with FPGA boards for
developing DSP applications. They'll make some reasonable design
decisions
(like a LPF before the A/D intended to digitize, e.g. video) and then,
when
you want to do something like IF undersampling, you can't get to the raw
A/D input.
Sometimes the mfr is responsive, other times they aren't. Sometimes it's
a
lack of technical support resources to give you the data you
need. Sometimes it's that they don't want the hassles of explaining why
the modified board doesn't behave as expected, or, that they aren't
confident it will work at all, and have no time/money/staff to find out.
You can contact me off list if you want specific companies that I've found
are good and/or bad to work with in terms of this.
So, it looks like we need to band together as a disgruntled user base
and mount a letter (e-mail) writing campaign to request that the
firmware be fixed so that we get the attention of Presonus and put this
issue on their radar. It should be a polite correspondence indicating
the problem, the fact that it is a known issue and that you would really
appreciate them making an effort to fix this in a timely manner. If
they get inundated with requests, it should expose the problem.
Given that they are a consumer equipment manufacturer, don't hold your
breath. They can make a perfectly reasonable marketing decision that it's
not worth it. Here's an idea.. see if you can figure out how many of
these
widgets the company sells total, and what fraction of that we SDR1000
users
are. Maybe looking at serial numbers might give a clue? If they're
selling 10,000 units/month, we're not a very big market in comparison. If
they're selling 10 units/month, then we are.
Here are the folks at Presonus that this effort should make an impact by
reading you letters. I am sending my letter to all of them.

Vegas at the end of April? Explain why providing this capability is useful
to ALL of their customers (not just the tiny number of hams with SDR1000s)
The customer service manager isn't really involved in product design

performance that might adversely affect their core clientele (folks

about producibility and driving the last penny out of the build cost.

While you're at it complain about the fact that you
can't install more than one firebox. The drivers do
not allow you to use 2 therefore you can not expect to
install 2 SDR-1000's using fireboxes. I contacted
them as well about this issue and got the were looking
at it real soon now.... real soon.
I think a better tact would be to encourage the Xylo
board guys to perservere

Jim,
Thanks for your comments and insight.
I hope you are not correct in you presumption that they might not fix it
for the reason you stated below, but that is a possibility. Even with
the limitations using 96K, the Presonus is a very good interface for use
with the SDR1K with the particular features it brings to the table, such
as balanced inputs, mic preamps, headphone jack and volume control and
the good dynamic range numbers.
If they do no choose to fix the problem, then I suspect I'll be looking
for a more complete solution in the future.
-Tim

I am sure all of you are aware of the issue with the Firebox related to

Welcome to the wild and woolly world of using devices with A/Ds outside
their nominal intended uses. The same problem exists with FPGA boards
for developing DSP applications. They'll make some reasonable design
decisions (like a LPF before the A/D intended to digitize, e.g. video)
and then, when you want to do something like IF undersampling, you can't
get to the raw A/D input.
