Re: FDM-SW2 DRM schedule source?

Neil Smith G4DBN
 

It goes to http://www.baseportal.com/cgi-bin/baseportal.pl?htx=/drmdx/scheduleini2

That is hardcoded as a Unicode string inside C:\Program Files (x86)\ELAD\ELAD FDM-SW2\ELADSampler.exe

Easy enough to use a hex editor to patch the executable and change that string to point at another site, or run a proxy with translation so any requests going to that URL are rewritten to go to your chosen site, so long as the returned content is in the right format (assuming SW2 obeys system proxy settings). 

If you don't have anything running on port 80 on the local machine, you could add a DNS HOSTS entry for www.baseportal.com = 127.0.0.1 (or point it at another machine on your local network or on a cloud host) and run a simple program to receive that GET request, fetch the new content from the alternate server and send that back as output as a response to the original GET.

It might be a step too far to allow a config file parameter to be used, depending on how much input validation is done on the existing source.

Subject: [EladSDR] FDM-SW2 DRM schedule source?

Hi All

Does anyone know how to change the URL that the SW2 software uses to download it's DRM schedule? What mine is showing now is a great work of historical fiction.

I'd like to change it to use the schedule database that I help maintain at the DRM Reception Project, https://www.drmrx.org, but I'm not sure how to change it, or if a custom format is needed.

Any help would be appreciated.

Cheers, Chris

Re: ELAD FDM-DUO tuning knob

Clint Chron
 

Hi Neil,

 

Perhaps there is more space behind the front metal panel that what I was thinking.  There seems to be a big gap from the end of the red line, going left to the front panel.

 

 

If so, then a Bourns optical encoder might fit.  The solder pins on an optical unit might be different from the layout of the factor unit, but that could easily be fixed with some jumper wires on the circuit board.

A single row ball bearing isn't going to be a full solution, as you need to allow for the shaft to move back and forth.  Perhaps a drawn-cup needle roller bearing is a better solution, but you always have a problem with lubrication, also any dust seals might cause additional friction.

 

If a drawn-cup caged needle roller bearing was fitted into an annular slot in a knob, and a hardened steel tube on a thin mounting plate was fixed into the milled round area in the panel, it would work well.  You wouoldn't be able to reach the grub screw though, so a different clamp, either a two-part version or a collet style, would be needed to tighten the knob to the encoder spindle.

 

That still doesn't fix the 30,000 operations lifetime of the encoder though.

 

An alternative solution is to use a Hall absolute encoder chip with a transverse magnet, mounting the chip and an 8-pin PIC in the space behind a hollow knob, with an annular bearing so the chip could be located centrally in the existing shaft hole.

 

Another way is to use quadrature proximity detectors looking at internal splines inside the knob.

 

None of those sorts of solutions would be good for a manufacturer though, way too fiddly and expensive.  Perfect for a machinist hacker radio ham obviously.

Hi Klaus,

 

Vianney – would it be possible for me to get a sample encoder of the model used in the Duo so that I could play around with different mounting options?

What is Elad’s position on a front panel oilite or ball bearing solution for the sloppy encoder shaft?

 

It appears that any brand of optical encoder is going to be thicker than the one used in the Duo. 

 

Here is a dimensional view of the current encoder:

 

 

Pending the non-availability of a better encoder, then the current issue could probably be resolved by installing an oilite bearing in the front panel encoder shaft hole.  The ID of the bearing would need to be big enough to take the slop out of the current shaft.

http://oilite.com/Products/Product-Line/view/parttype/ppl/24/pt/2

 

Worst case, a bearing tight enough to get rid of the slop is going to detract from the current smoothness of the factory encoder.

 

A ball bearing might even be better. 

https://www.lily-bearing.com/ball-bearings/miniature-bearing/miniature-metric-bearings/mr106/

 

However, the manufacturing tolerances for the solder tab mount on the encoder might not be good.  If so, then the encoder would need to be mounted in the front panel ball bearing before the encoder is soldered to the circuit board.

With a ball bearing,  they should be no slop.  The fit between the encoder shaft and the ball bearing would need to be loose enough so that the shaft could slide in the bearing.   It would be very easy to enlarge the shaft hole on the metal front panel and glue the bearing to the panel.  I am guessing that a quality ball bearing, purchased in quantities should be no more than a couple of dollars USD.

It is a much bigger part compared to the DUO(r) encoder and it's got no push function.
Price for the part is 40 USD for an order (single piece order) at digikey.
The life cycle for this part is spec'd for 10 million complete turns.

 

 

There is an even more robust version of this encoder available (200 million turns) for a price adder of about
25%.

Hi Terry,

 

That VFO encoder in the DUO(r) is a very lousy part, as far as mechanical robustness is concerned.
This weakness manifests itself *IF* the DUO(r) is mainly used as a stand-alone radio w/o PC control,
when tuning a frequency is done via this VFO encoder on a regular base.

 

BTW, the other encoders are no better, but they are not being used as often as the VFO knob in
a stand-alone environment. So they 'wobble' later in time and due to their smaller knobs not as
drastically as the VFO knob (they are also not used in a sort of 'spinning' mode).

 

My DUO VFO encoder also wobbles (early model). Not nice!

 

The only thing you can do, if it's getting too nasty, replace that encoder with a new one :-))
of compatible pin-out and size. They are lousy cheap.

There is not enough space in the DUO(r) between the front panel board and the front panel
in order to install a mechanically more decent encoder (limited by space).

 

The TM-2 option is a no-go option for a stand-alone operated DUO(r), as it requires a PC
running Windoooze and ELAD SW-2 software on that PC (TM-2 connected via USB).
I have no clue what kind of encoder(s) ELAD uses for the TM-2 add-on.
As said, this thing only works when running the DUO(r) via PC control.

 

This VFO encoder issue may be the result out of a cost-down design, which can also be found
in a number of other - in our case - ham radio sets, e.g. Yaesu FT-450, which, btw, is a 650 $
radio @100 watts and ATU integrated.

 

I'd be gladly spending an extra up to 50 $ if that DUO(r) VFO encoder was of high quality!

 

73, and stay safe!

Hi all,

 

My ELAD FDM-DUO tuning or VFO knob is very wobbly. I have checked the grub screw that secures the knob onto the encoder shaft and that’s OK. I have taken off the cover and there is nothing obviously loose. Does the encoder need replacing or is there some bushing that has worn ?.

Hi Klaus,

 

Vianney – would it be possible for me to get a sample encoder of the model used in the Duo so that I could play around with different mounting options?

What is Elad’s position on a front panel oilite or ball bearing solution for the sloppy encoder shaft?

 

It appears that any brand of optical encoder is going to be thicker than the one used in the Duo. 

 

Here is a dimensional view of the current encoder:

 

 

Pending the non-availability of a better encoder, then the current issue could probably be resolved by installing an oilite bearing in the front panel encoder shaft hole.  The ID of the bearing would need to be big enough to take the slop out of the current shaft.

http://oilite.com/Products/Product-Line/view/parttype/ppl/24/pt/2

 

Worst case, a bearing tight enough to get rid of the slop is going to detract from the current smoothness of the factory encoder.

 

A ball bearing might even be better. 

https://www.lily-bearing.com/ball-bearings/miniature-bearing/miniature-metric-bearings/mr106/

 

However, the manufacturing tolerances for the solder tab mount on the encoder might not be good.  If so, then the encoder would need to be mounted in the front panel ball bearing before the encoder is soldered to the circuit board.

With a ball bearing,  they should be no slop.  The fit between the encoder shaft and the ball bearing would need to be loose enough so that the shaft could slide in the bearing.   It would be very easy to enlarge the shaft hole on the metal front panel and glue the bearing to the panel.  I am guessing that a quality ball bearing, purchased in quantities should be no more than a couple of dollars USD.
