Rob Sherwood has several YouTube videos and he always makes the same point (paraphrasing - you don't buy a radio on one number).

go to the 28 minute 50 second spot to hear it in his own voice.

Perhaps a solution for urban radio operators will be SDR receivers capable of synchronous receive from multiple antennas, allowing future computer DSP multi-input noise reduction algorithms, perhaps with far more sophisticated algorithms than just diversity phasing and spectral subtraction.

Two current examples of radios might be the SDRPlay RSPDuo and the Red Pitaya 288-16.

Do any of the Big 3, 4 or 5 amateur transceiver manufacturers have dual antenna dual synchronous SDR receiver capability?

Urban? I'm pretty much at the op of the "L" where it says Poncey Highland on this em73ts map. :-)
http://www.levinecentral.com/ham/grid_square.php?Grid=EM73ts

I viewed the video demo with RSPduo and SDRplay software. Is there any other phasing software that works with the RSPduo?  I did not see anything for Red Pitya? The 16 bit RP board is considerably more expensive than the 14 bit. For an urban setting, is the extra range really necessary?

I've got a reasonable understanding of signal processing from long ago days in the oil industry. But, my programming skill is along the lines of the guy who does not know which end of a soldering iron to hold. I'm in the process of installing some 20' verticals in a triangle in the back yard to use with the MFJ-1025. I'm intrigued by the idea of some software handling the phase shift and level control.

This should probably go in it's own thread.

Thanks.

The current Anan radio/software setup rules for noise reduction.
They have beam steering as well as some sort of noise sampling on a close by frequency and then phase it out where you are listening, sore of like pure signal on RX.
I have been told its amazing.

Hi Bob, I have been using a vertical that is around the 40 mark with one simple radial wire as my noise antenna on my cheap and dirty modified MFJ 1025, simple relay mod to remove the RX noise antenna from the system and most of my transmit antennas are horizontal. I use the vertical for noise which I know is thinking out of the box but it works and works well. Before FPL had taken care of the S9+ power line noise when I first moved here I used this system to get the noise down to almost S1 but today since they finally fix the power line noise I do still use it for other urban noise around my area, the improvement sometimes is night and day but if you could get the radio to do that automatically that would be excellent but even with the Anan you have to tune it.
I do plan on replacing the cheap pots MFJ uses but this system allows me to works stations that would be no copy before or just using the transmit antenna. I would be real interested on how array of 20' verticals work out. I might change the noise vertical to a 40m OCF dipole with the long element vertical and the short wire horizontal so it can be a multi band noise antenna, for that mater e4ven the 80m version could be used cause swr doesn't really come into play its really about capturing enough noise well on multiple frequencies so you can phase out the noise not the signal.

I talked (on the air) with someone using the Anan sdr radio and software who said the software does exactly
that, it listens to wideband noise (a large swipe of frequency) and nulls it out leaving only (mostly) the signal you want.
He said it takes about 6 seconds from turning it on and then its like magic.

A vert makes a GREAT noise antenna for these systems.

I'm sorry I am not interested in the Flex or Anan rigs at this time, I have a few friends who own either the Flex or Anan or even both, I have seen video's of how the Anan works bit not interested in a radio that I have seen my same friends freeze up and then they have to re boot both there computer sand the radio, that is NOT for me. I see this even when these hams have a computer especially built for there radio and this still happens plus service for these radio's is half way around the world plus with the Anan its open source which tell me its constantly changing so you spend more time frigging with the dam radio then using it. The Anan is for the computer geeks, I get it but what some of use who live in an urban environment are trying to do is try and use our existing radio and improve or signal to noise ratio without the noise.
I am not a Flex or Anan hater its just NOT my cup of tea and I would rather operate my radio for enjoyment then screw with some software half the time!

BTW I have had ham friends visit our home and check out what I have done with the modified mfj junk noise box and they were extremely surprised plus they owned Flex 6500 radio at there home. What is funny is that they enjoyed using a knobbed SDR radio again and were kind of board with the mouse and needing a computer all the time to operate there radio!

I am not suggesting anyone buy any radio, just saying what I have been told.

I suspect people have problems because they do not know what they are doing, or do not know much about radio or computers.
I have had almost every SDR and have never had any problems with any radio not working correctly.
I get a half decent computer ($250.00) and only run the sdr, no other programs at all, and they just work.
I also ground my station and even though the antenna is close to the shack, I do not have problems.
I know very little about computers (software really) but know you will not have good results if you use a windows computer for sdr with updates on, and virus protection running, and use it for Email and shopping, and logging, and digital programs and the kids play games on it, and it sits on top of the amplifier and has 30 foot speaker wires running all over next to your end fed antenna.


I might point out this is the SDR FORUM so not wanting a computer is a bit odd since you NEED a computer (of some sort) to run SDR.
There are only a few real sdr radios where you do not need a PC, others have band scopes and dsp but are not the same as what something like an Anan can do.

The Icom 7300 is a real sdr radio but because it does not use a PC, there are MANY things it can not do.

Since Flex moved a lot of the sdr work into the radio, they are now very limited in what they can do.

I suspect nothing out there other then the Anan is really going to do better then the MFJ thing you have now....

But the computer need not look like a Windows PC box.  Some radios (7100, mcHF, etc.) have the computer (an embedded processor or Turing-complete DSP) built-in.  The Red Pitaya has an ARM CPU embedded inside it's FPGA.  I use a Raspberry Pi 4 as one of my SDR computers.  And you can do SDR with a mobile device (Android, iPad, etc.) which often has a very powerful computer hidden inside (my iPhone benchmarks faster running SDR code than most i5 PCs).

I think SDRPlay has some software that works with the RSPDuo.

Some people working on the Hermes Lite 2 project are experimenting with using 2 HL2's, ganged together to do diversity Rx.  Currently the beam forming software is being tested for FT8 spotting, but adaptive diversity noise cancellation could be next.

Yes, that is all true, but unless you can play with the software like KE9NS does, and whoever does the Anan software, you can not just update a radio to enable pure signal, or some of the noise reduction, or the pro audio tools that are now included in some software.
You only really get what you have when the radio is new and a few rare updates that fix or enable little things.
The old Flex radios like the 3000 and 5000 now have all the things KE9NS has added.
The Hermes can run on a computer, and even other platforms can be upgraded to support some things.
You are stuck with what you have (mostly) with the 7300, 7610, ftdx radios...
That might be fine, for a while....

I wish they would make programs for the Apple computers, I hear they do not have all the windows problems. I DO hate windows 10 with a passion. 7 was not too bad.

Working on it.  And there are other radio related apps in the App store and online.  For instance, linHPSDR and SparkSDR are reported to run on a Mac to operate the Hermes Lite 2.

But the problem is who is this "they".  Everybody seems to want someone else to write Mac programs, but still include all their favorite Windows app features.

I think its great that people write software for SDR radios and do not charge, but I would PAY for powerSDR mrx to run on a mac.

I see there are quite a few ham radio programs for the mac, but not many sdr programs.
