Hi Everybody;

The MDSR group has released version 2.51 of the popular 12kHz IF modulator and demodulator software. The new software includes now AM (synchronous detector), DRM (Dream) and digital modes provided by FLDigi, which also includes a logging data base. This makes the MDSR the most versatile IF modulation and de-modulation package which can be used for free as long as it is used for amateur radio use.</SPAN></SPAN>

It didn't take long to realize it's not for me. Not sure it would work with my rig and anything that requires me to compile goes in the "later" pile anyway. All those FT and IC numbers and "any 455kHz IF transceiver in transponder mode and a computer interface" from the Yahoo group should have warned me not to try. Plus all the other apps it requires to work.... I installed it, but didn't get far. 8/

Hi Frank;

As I can see you are using Power SDR which is a very nice program if you can afford the hardware. The fact is that Flex radio started to charge for part of it. This is quite disturbing because it was made up by countless volunteers and now Flex is acting like they own Power SDR.

It looks like to me you did not even try to make it work and that the success of MDSR scares you! And now you discourage other users from trying it!</SPAN>

You should be ashamed of yourself! This is HAM radio and experimenting is a big part of this hobby. Do not discourage that process by forcing your opinion on others.

All the best;

The MDSR Team</SPAN>

Let's see, you ask for comments on your product; someone posts something that isn't singing the praises of your product, you get your knickers in a knot. While your product may or may not be worthy, sorry, I'll pass on your product (because of the attitude) and stick with my Flex. Oh, by the way, Power SDR is completely FREE, and, experimentation with it is welcomed and encouraged by Flex.

We do not have a problem if someone makes constructive comments, but to just put something down just because is not called for.
By the way: The MDSR is not a product, it is a research tool and lots of HAMs have contributed to it.

It is funny that you are complaining about my attitude and this just shows that because you can afford a FLEX radio you are better than the rest of the HAM community. And at the same time you create the believe that FLEX and Power SDR is the only way to go.
When some one else comes along and makes SDR accessible to everybody, even people with low budget you get threatened in your superiority complex and you feel the need to put everybody down.

That is not right!

Alex, right from the beginning you've picked on Flexradio/PSDR users. You are the one that brought up PSDR. I never made the comparison, yet you couldn't wait to say something about it. Completely off topic.

Then you come back with silliness such as "uneducated opinion", "the success of MDSR scares you" (lol! your success or failure has zero impact on my life, so why you'd say that I have no idea.), "should be ashamed of yourself" for "forcing your opinion on others". You obviously have a bug up your ass about Flex/PSDR. Your best competitor, so I can see why you'd talk it down, but it's unprofessional.

I don't want to take the time to compile, build a kit, add more wires, etc. just to discover MDSR doesn't offer me any more than I have. I love trying out new software, but it has to fit in my existing system. Which most programs do. I still don't know if your product works with a Flexradio or not. I think not. You're too busy bitching to actually address any issue I had.

Sorry you didn't find my comments "constructive". Neither are your comments to those that you think are "better than the rest of the HAM community" just because they own a Flex.

It took me years to save up and sacrifice other things I wanted in life to get one. Because it IS the best. Methinks you are the one that's scared.


Besides, why do this:

Flex radio is better for appliance operators, but at a price.

MDSR is another option for some people, but not all.

Same goes for Flex radio.

Why the pissing match ?

Again Alex, out comes the attitude. I was going to write a lengthly reply; however, I'll suffice it to say that your attitude in your responses have COMPLETELY turned me off to the thought of even trying your "research tool" (product). Also, (Dare I say?) I believe your attitude is turning and will turn away many others.

Best of luck in your endeavor.

Alex VE7DXW is a very good friend of mine. He and I have been collaborating on the MDSR project inasmuch as I have placed my RF lab at his disposal. Alex and I have been conducting performance tests on the system at each stage of the development.

Alex and his Belgian co-developer Guy ON6MU have been, and still are, working very hard on the MDSR program. In my view, they are certainly deserving of consideration, and at the very least they merit a courteous hearing. MDSR is not really positioned to “compete” with established SDR products; its mission is to provide an inexpensive solution to the task of adding SDR-type functionality, including a GUI with extensive radio-management features and a spectrum scope, to conventional superhet-type receivers and transceivers. It is our hope that MDSR will appeal to the experimenters and builders in the amateur community who are still interested in trying something new.

Alex,

Thank you and your colleagues for further rolling out the feature of synchronous AM detection.

I have received emailed recordings of AM QSOs made in the "SAM" (Synchronous AM) receive mode, and it's an outstanding way to participate in our part of the hobby.

Most of the operators I encounter who are using synchronous detection are also running some version of the Flex transceiver, although a few are using the Sherwood SE series on a traditional receiver.

Me, I'm still "stuck" using the high quality diode load terminals from an R390, an R390A or an SP600 receiver. Not bad, but not as good ...

Here's hoping more will acquire and implement your system to help spread the joy of synchronous AM reception...

Alex,
I think Frank k2ncc and Jim W8LGZ are right.
There is something as freedom of speach and expression too. And the way you replied... Not my cup of tea.
This being said, I too find this MDSR thing way to complex to start with! You need a whole lot of study just to get the hang of it. Surely the MDSR java is full of complex settings to get lost in easily.
The idea is good, tapping from mf and demodulate it with software, but does it need to be so complex? And we still need an expensive rig to get on HF. No rig, no MDSR = no radio = no HF.
I think MDSR has a future in a different category but not as SDR. Perhaps in analysis of the spectrum, DSP and so. I do know.
Of course this all is my personal opinion. I do not want to bad mouth MDSR at all. It has its purpose for the experimenters out there.
MDSR is not for me but please do not hesitate to give it a try. I could see that there was a whole lot of work put in this product.

Sorry to hear that you where not able to implement MDSR at your station setup, seeing from your QRZ profile seeing that you are running a Flex Radio put you in the rarefied group of individuals for sure.
I on the other hand only have some "Classic" rigs at my disposal for experementation (IC 706MKII, IC-746 non DSP) and my available computer for use in the "ham shack" (located in a corner of my garage) is is a bit dated in comparison to your setup so the MDSR route was the the most cost effective method for me to get into DSP "like" radio, I believe my total expenditure was no more then $70.
Yes the operation of the MSDR software required a small investment of my time and gray matter since it is so Flex-abel and this was a good refresher for a "old timer" like me to the latest software methodologies in DSP radio.

In fact MSDR and its use got me into even better low cost DSP radio with my aquiering of a few rather inexpensive RTL2832u E4000 / R820T type dongles and a HF converter for them for a total expenditure (dongles and HF converter) $90.

So let see $70 + $90 =$160 for this low sum I now have a 50 MHz to "Daylight" multi format DSP receiver, followed with a VLF-HF DSP Receiver via the dongles and of course the MSDR abilities on my classic icom radios.

MSDR is what got me into the DSP game at extremely LOW COST in comparison to the cost of a FLEX type radio, and just think I can still use the classic radios without the need of a computer oh and yes I do have a laptop and I do use it for Digital modes with my classic radios.

If you require help I am willing as a old timer to act a "elmer" to assist you in getting MSDR compiled.
Best Regards.

I have some questions to ask of the SDR users on this board. Do you notice a delay? I have listened to a NWS Weather Station with a HT at the same time tuned my DVB-T USB dongle to the same station. Now without feeding the two signals into Audacity to see eactly how big the time lag is, it appears to be more than one but less than three seconds. Would this present a problem with breakin CW?

I have also turned on the CPU scaling tool in Ubuntu and have a Load of 88% to over load, this is with an AMD Sempron at 2Ghz, any one else notice these loads?

I am using HDSDR, SDR# and in Linux GQRX. All three exhibit the same symtoms.
