Hello Folks, I have been remiss in introducing the Multus SDR, LLC team. So, here is an introduction. Multus SDR, LLC is a team of associates, five to be exact that contribute their unique talent and skills to designing and producing our products. A little over three years ago I set out to produce the Multus SDR Basic. Yes, it is a clone of another well known rig that the author and owner decided to stop producing. I liked the architecture of the rig so much that I set about determining what would need to be accomplished to produce the rig. As luck would have it, I met Tim. Tim (KQ8M). Tim was the first person to join up with me to help produce the Basic. Tim asked me what I needed help with and I mentioned I didn't have a clue how to use an EDA (electronic design automation). As it turns out, Tim is a wiz at learning and using EDAs (electronic design automation). Tim went to work and produced the design files for the Basic. Since then he has designed two other boards for the team. The mWattmeter and a yet to be released CW interface board. Tim was the key to getting Multus SDR off and running. Without him, there would be no Multus SDR. Now we needed a company to produce the PCB. One day I had a JT65 QSO with, Richard ((VK6FR). He happened to take a look at my QRZ.com page and noticed the rigs I was using (the predecessor of the Basic). He sent an email to me asking where he could purchase one of these rigs. I said you can't since the owner quit producing them, but wait! I let Richard know I was in the process of attempting to produce the Basic. Richard has extensive background and experience with having PCBs produced and contacts with manufacturers. He offered to help locate and coordinate having the PCB produced and the Multus SDR Basic Full DIY was born. Richard then prodded me to offer a more completely built version of the Basic and the Multus SDR Basic Semi DIY was launched. Richard  also happens to be a RF engineer. After a bit more gentle prodding , Richard convinced me to offer an all band version of the Basic. Richard went to work and produced the Multus SDR Proficio design. Working with Tim, they produced the PCB design files and the Proficio was born. One day I happened to have a QSO with, Jim (N7CXI), I don't remember exactly when. We got to chatting and Jim let me know that he has a strong background with audio processing and SDR in general. Realizing the team needed a person well versed with the software aspects of SDR, I asked Jim if he would like to join the team and he accepted. Jim is an expert in the field of audio processing and has deep insights into how this stuff works from a software perspective. He is the teams go to person when the rest of us go, huh? Over the course of our association, Jim decided to purchase a laser burner. He offered to produce the Basic enclosure and from there has designed a produced all of Multus SDR's enclosures. Recently we have added a new team associate. Stew (KF5KOG). Recently Stew offered to perform a build for one of customers. So (being the manager type that I am), I asked Stew if he would like to offer building kits as an on going service.  He accepted and already has performed a number of build services. Stew has the expertise and all the test equipment to provide a completely tested and checked out rig. And then there is me (W4MMP).  I am the front man (so to speak) of Multus SDR, LLC. My background is in technical management with a focus on super scale database management systems which has absolutely nothing to do with Amateur Radio. Go figure.  As for technical contributions to Multus SDR, LLC., my area is firmware. I prefer firmware development verses host application development. So, that is the Multus SDR team. I am deeply indebted to these folks and without them, Multus SDR would not have happened. -- Thank you for your support and business, 73, The Multus SDR,LLC Team, Ron / W4MMP

Hi Folks, The April refresh is almost ready for release. The name has been changed to simply MSCC (previously MSCC-Core). This release supports the soon to be available MFC and the coming Potentia. Salient features: 1) MFC support 2) Potentia support 3) Temperature compensated main oscillator frequency stabilization. 4) Frequency display trailing digits auto zero. Without the MFC or Potentia, you will not see much of a change. Most of the development work has been under the covers to support the new products and to make other existing features easier to use. The power calibration routine has been extensively revised. The power calibration values are no longer stored in the Proficio EEPROM and are now stored on the PC. This permitted the power value slider to adjust the power output in real time (no more apply button). The frequency calibration routine has the same user interface but has been substantially revised to support temperature compensation. The new trailing digits auto zero feature works like this. If the frequency display is set to 7.074.123 and the "1" digit changed, 2 and 3 will be set to zero. If the "4" is changed, 1,2 and 3 will be set to zero and so forth. This feature is optional and there is a check box to the right of the frequency display to turn it on and off. It is on by default. Contrary to what I said in a previous post, I was able to maintain backwards compatibility in the Proficio firmware for SDR host applications such as HDSDR. However, a word of caution. Since power output calibration values are no longer stored in the Proficio, it will be very easy to over drive the Proficio. You must have a method to monitor your power output (watt meter, oscilloscope, etc). The frequency calibration continues to be stored in the Proficio EEPROM but without MSCC, temperature compensation is not available. There is more testing to be performed before MSCC is released. The hope is this release will be very stable and for as much as possible, bug free. Installations of MSCC-Core and MSCC can coexist on the same computer. The initialization files for MSCC are stored in a unique folder and will not overwrite your existing MSCC-Core files. However, falling back to MSCC-Core will require the Proficio firmware to be changed to the version compatible with MSCC-Core. -- Thank you for your support and business, 73, The Multus SDR,LLC Team, Ron / W4MMP

Hi Folks, We will be offering a number of new products in the coming months. 1) Metal Proficio Enclosure. Below is a mock up of the design. It is shown with the optional MFC (Multi Function Controller), minus the knob. It will available without the MFC with simple a plain front panel. NOTE: The enclosure that will be supplied will have vents. It is identical to the one shown below but has vents along all four corners extending front to back. Then enclosure measures 7" wide X 4 7/8" deep X 2 1/4" high. \ 2) MFC (Option). The MFC is combination Tuning Knob and controller. The three buttons may be programmed to perform various functions when pressed. They are configured with MSCC-Core. It also supports a 2X16 display. The display will show frequency, mode and such. Just how many things it will display depends on what I can fit in the Proficio microprocessor. NOTE: The MFC is plug in compatible only with the Proficio Version 4.X PCB. The Rev C Proficio PCB can be made compatible with a cut and jumper hack. PCBs prior to Rev C are *not* compatible (unless a lot of hacking is performed and I really don't recommend it). 3) Cwattmeter. The mWattmeter is being replaced with a new version. The Cwattmeter supports all the functions of the mWattmeter but adds a 20W to 100W range. An enclosure will be available for the Cwattmeter and is the same style and size as the Proficio enclosure. 4) Potenia (100W Power Amplifier). Building upon the current Multus SDR, LLC, technology, we will be offering a 100W power amplifier. It incorporates much of our existing technology to control the amplifier. The ATU Port Expander and the Cwattmeter technologies have integrated into the design. The Potenia will be controlled and managed by the Proficio and MSCC-Core. The Potenia has been specifically designed to be used with the Proficio and only the Proficio. Without the Proficio, the amplifier will not function. We have no intention of producing a general purpose amplifier (there lots of those available). The Potenia is designed to provide the best operational characteristics with the Proficio. The amplifier will be housed in an enclosure very similar to the Proficio enclosure (only larger). The above products are now in the prototype phase. The first product to be released is the Proficio enclosure with the plain face plate for folks who have been asking for a metal enclosure. Next will be the MFC option and the Cwattmeter. We have a fair amount of prototyping to perform on the Potenia so that will be last and will be least 3 to 4 months before it is available. We don't have the pricing yet. -- Thank you for your support and business, 73, The Multus SDR,LLC Team, Ron / W4MMP
