Re: email address for robby wb5rvz?

 

Hi Clinton.
He did not own Soft rock business. Tony Parks did and sold it to Ben Cherry
here:

the reason I was looking is I wanted to reference his websites. I think he
is still a ham and I wanted to as for permission.

Thanks for your note.

Re: FINALLY, I got 192K bandwidth on the Softrock display!

 

to set the gain you can open a terminal and run alsamixer , select the card
, and then toggle to the input or AtoD gain .

Hi All,

This is a continuing saga of my getting a Softrock LF operating properly

one Tony sent me seems to work quite well (with a few quirks). But one
thing I could NOT do was get a 192KCs bandwidth in the NDB band where I
listen. About 96k was the best I could get.

I had bought a new Creative Soundcard to install in my Tower computer as
the soundcard it had seemed a bit "hissy". This is the soundcard I
bought, as it said it was 192k.



After I finally got into the Win 11 setup for the card , try as I might,
I couldn't do any better than 96k, and that is all that HDSDR would let
me do.

Finally, in desperation, I plugged the Softrock into the soundcard that
came with the 'puter, a Realtek that is apparently part of the
motherboard. Well, imagine my surprise when I went into HDSDR and it
let me set the card up for 192K, and I can see that bandwidth in the
display. Seems to work quite well, except that I do get a "clip"
indicator. I've NOT figured out a way to lower the gain of the card
that works, (Win11 is TERRIBLE about letting you change things). But at
least it IS working, but I noticed that I seem to have three very strong
bands of IMD or "noise" (not listened to it yet) in the waterfall.
Something that isn't "real" as I don't hear them on the Yaesu receivers
using the same antenna/ multicoupler, etc.

But otherwise the receiver seems to work well, in three nights recording
(while it was still only 96k) I logged quite a few NDB's, including
several Alaskan ones that I always welcome here. . .

Re: FINALLY, I got 192K bandwidth on the Softrock display!

 

This is interesting! I haven't used my Softrock RX Ensemble II since Linux
Mint (apparently) dropped the driver for my M-Audio 192k card.

The motherboard on that Dell died (the bad electrolytic capacitor fiasco)
and now I'm using an Asus VivoPC VM60 mini computer with Debian 12 KDE
Plasma. (Dual boots into Manjaro.)

Any 192k (or higher) solutions for that? USB maybe?

Softrock LF Receiver off by 10KHz last night

Philip Atchley
 

Hi all,

Tony was very kind and sent me his Softrock LF receiver.? It seems to be working very well, except for ONE thing.? Here is a breakdown of what I've seen on the overnight recordings I made using HDSDR (my program of choice).? It's been a few years since I've last used a Softrock, so I might be missing something.

1.? On the night of 9 October I made recordings for the full night with an LO frequency of 220KHz.? Everything went well, except for a strong spur on the LO frequency.? I seem to remember that can be due to not using isolation transformers between the receiver and computer sound card.? Like I said, it's been awhile, and that wasn't a great concern at the moment.? I logged a number of beacons and all were on the proper frequencies.

2.? On the night of 10 October I again did an overnight recording, this time using an LO frequency of 250KHz.? Again, everything went well, everything on frequency and I logged a number of beacons (their number is rapidly diminishing).

3.? Last night I made an overnight recording using an LO frequency of 380KHz so I could cover the upper range of the NDB band.? This time everything is messed up frequency wise.? The frequency of all NDB's read exactly 10KHz high, this from well known and stable ones like MOG on 404KHz.?? NOTE:? I DID try using both installs of HDSDR (V2.76 & V2.80) to make sure that wasn't the problem, but both read the same.

As I no longer have any NDBs within daytime range I can't check things out until night falls.

Softrock LF, YIPPII, it works! A long saga.

Philip Atchley
 

Hi All,

Awhile back I posted a message saying that I was looking to purchase a Softrock LF receiver, were they still available and where? ? This is a rather long message, as I'm going into obtaining, the arrival and installation of my 'new-old' receiver.?? OK, here goes.

1.? Thanks to the folks on this list I discovered where I could order the set, and proceeded to do so, even though with the severe rheumatoid (sp?) arthritis in my hands I knew it would be very difficult to handle the small parts.? Some days I can hardly close my fingers to make a fist. That's something that didn't bother me years ago when I built my previous sets.

2.? THEN, I received an email from Tony Casorso offering to give me his Softrock LF that he apparently hadn't used in years.? Thank you Tony!? For me this was a big case of Deja-Vue (nobody ever gave me an 'A' for spelling) as Tony had loaned me that very same receiver many, many years ago and it got me started on the trip down the SDR trail.? With it I learned how to do overnight recordings of the NDB beacon band.

3.? But to make it ready to install a Softrock I really needed to do some upgrades to my computer.? It is a high performance "tower computer" with Win11 on it.? In addition to my radio hobbies, I collect old time radio shows, old TV, old Movies, old comic books etc.? Mostly public domain, I share about? 112.7TB of files on various sharing hubs.? So, I have a total of 15 hard drives running 24/7, they vary in size from 10-18TB each.? 13 of the drives are "internal" drives that are mounted in two drive storage bays (5 bay & 8 bay).? With other peripherals installed all my USB ports were in use, and I had a couple external USB hubs installed too.? Problem is, if I was downloading or uploading files, with all those drives are churning away, it caused frequent data collisions and other problems.? So, I decided to install a new PCIe card in the 'puter along with a new Sound-blaster Audigy FX? PCIe card just for the Softrock.? The next paragraphs explain the problems I had with both of those cards , it may help somebody in the future troubleshoot card installation problems.? NOTE:? I'd installed similar cards in previous 'puters with NO problems.

4.? Installed the? FrescoLogic"USB3.0 Super Speed PCI Express Host Card" (7 USB ports).? Reading the (tiny) instruction sheet I installed the drivers for it from the provided CD (THANKS!) Rebooted the 'puter and tested the ports, nothing, DEAD ports! In checking the devices in the list of installed devices there was a yellow !? indicating that device wasn't working (I knew that). After a couple of hours working on installing, rebooting and so forth I finally went to their web site and looked for their help section.? Found it, the FIRST problem covered was "card not working" after install (or words to that effect).? The gist of the story was that the install CD is ONLY to be used on machines running Win8 and earlier.? Win 10 (it didn't mention 11) is to NOT use the CD, but during installation have windows look for the best driver which is part of Windows (again I have Win11).? After uninstalling it and then reinstalling? and letting Windows do it's thing the card works perfectly!?? Gee, thanks, all it would have cost would have been the price of a small piece of paper a few inches square with "DO NOT USE CD ON Win10 and LATER"!

5.? Installation of the Sound-Blaster PCIe card.? Should be fairly straight forward, I've done it before.? So after installing the card everything looked good, the 'puter saw the card as a valid sound card.? Plugged the Softrock into the Line In port and fired up? HDSDR (V.2.76) which I prefer.?? I kept getting an error to the effect that the Soundcard didn't recognize that particular file format.? After going around in circles for awhile I decided to try HDSDR V.2.80.? Imagine my pleasant surprise when the Softrock took right off and I was getting the expected waterfall and everything seems OK now.? Just for grins I retried? HDSDR (V.2.76) and it too worked just fine.? So I'm really NOT sure what the problem was at the start, but all is good at "The Beaconeer's Lair" (what I've called my shack for many, many years)!

Re: Receiver availability?

 

Hi Phil,

I still have that LF softrock that you borrowed from me years ago. It is sitting in a drawer and I would be happy to send it along to you if you want it. No charge.

As far as overnight recording of the NDB band, I used the Elad S2 for years and now I use the S3. Both have a 384Khz bandwidth which covers the band pretty well. I get about 64GB per night.

Subject: Re: [softrock40] Receiver availability?

Hi Zack,

Thank you for the info. Yes, I have a Airspy Discovery HF+, as well as
an SDRplay, both being good receivers. A couple problems for the task
I typically use them for though. Except when using a Perseus (I sold
it) my program of choice for overnight recordings of the NDB band
(~200-530KHz) is HDSDR (yes, I know it's old, but I'm used to it and at
80yrs old new software doesn't come as easy as it used to). Problem is
I've never been able to get a reasonable size recording from either of
those two receivers in HDSDR. A 2GB file only holds about 4.5 minutes,
meaning that an 8 hour night creates about 215GB of files, eating up
hard drive space rapidly (though I have about 120TB of drives on this
machine most of it is occupied by movies, TV shows, music, comics etc
(ALL Old) that I share on the hubs. I don't just record the NDB's and
then toss the files when the CLE (Coordinated listening session) is
finished, I archive them for posterity. I have files of NDBs going back
to 2016 (they are rapidly being decommissioned). The Softrock
recordings I have going way back (and used a 192K soundcard) would give
me about 43 minutes per 2GB file.

So, that's why I want to get another Softrock, seems like I go through
receivers about as often as some folks change their socks ;-)

I have the HF and the LF Ensemble II and a third that I was going to build.
The HF version has one 74AC74 divider in it. The LF version has an
additional 74AC74 divider in it. If I remember correctly, the HF version
would tune down to about 900 kHz and the LF version would tune down to
about 180 kHz. An additional divide by 16 board was supplied by Tony on
request that would allow the unit to tune down to the tens of kHz range, if
I remember correctly. That's the one I was building but never got around to
finishing it.

By the way, the Airspy Discovery HF+ is an outstanding SDR receiver that
goes down to 5 kHz (!). It's the best I've seen in the LF/VLF range.

Guy,

Thank you, I ordered the RX kit and the 16X board (16x board only
5.00). I seem to remember that the Softrock LF Receivers that I built
in the past all had the 16X divider already on the PCB, just had to use
different jumpers. Of course they came with toroid cores for the LF
bands instead of HF. Not sure what I'll do for that. . .

Now, I just hope I'll be able to build it well. I have built a
gazillion things since I first got interested in Electronics at age 10
(about 1953). But I have pretty severe "RA" (Arthritis) in my hands
now, especially the right one. Fingers are stiff.

By the way, I had an Uncle on my mother's side who was named "Guy" (last
name Surber). But we all just called him "Uncle Bud".
