Re: Bug in FDM-SW2 ?

Michele
 

I'm not in front of the fdm-sw2 atm (i'm using a different pc..i'm in the garage trying to build a qfh antenna :P).
Let me see if i've understood...
To avoid that problem, i can click on "Lock CF" so the tuned frequency will be always on the center of the spectrum (visible spectrum=LO Range right or not?).

So we should have a lock CF command on TCP and CAT connection right?

If i'm right....PLEASE ADD THAT COMMAND!!!!!!!!!!!!!!

Many thanks, let me know if i've understood well or not.


Re: Bug in FDM-SW2 ?

Henry
 

Right, this is again that Lock CF problem. When you tune manually, you shift the frequency within the LO range. Your TCP command tunes the LO, but you have just created a shift manually. The tuning frequency follows that shift (difficult to explain in words).
You have to engage Lock CF.
This is one reason why we need a Lock CF control not only in the CAT but in the TCP control as well. Or at least a tuning and LO frequency control. But this has not been very stable in the CAT section already. When setting LO and tuning too fast in a sequence the SW2 often did not follow. You had to insert delays or verify the result and repeat the action until both matched.

You can see the problem in this video:

I hope to have explained the problem.

Good afternoon Bob

I use the TOKYO HI-Power HL-50b.

Its pretty much bomb-proof, delivers 45 watts (ish) and plays very well with the DUO -- without the need for any connection between the two items (Just use the RF sense on the HL-50b.)

You can pick one of these excellent amps up for circa £150 second hand.

There are many other options for more (and less) £'s.

TCP Command on fdm-sw2

Michele
 

Hi!

- Will you implement the set tuning freq on the tcp protol? I only see the command to set the lo freq.
- Will you release the updated sw today (as you said yesterday?)

Many thanks!




Re: SW2: working split - help please (long question sorry) WISH TO ELAD TEAM

Neil Smith <neil@...>
 

The part which I find confusing for the HF pileup case is:

RX1 is on the DX station for receive.
RX2 is set to somewhere in the pileup.
TX is set to the RX2 freq.

Now I want to move the RX1 frequency a little as the DX has drifted off channel.� I click on the RX1 button,� *BUT* that disables the RX1 speaker and enables the RX2 speaker, so I have to enable the RX1 speaker and disable the RX2 speaker so I can still hear the DX.� Is that correct behaviour?� All I want to do is change the RX1 frequency.

OK, back to the pileup.� I am listening to the RX1 channel, TX is set to the RX2 channel.� The tuning context is still red for RX1

Now I want to adjust my TX frequency again.� I would expect to click on the RX2 yellow button or the yellow freq box next to the yellow TX button.� When I do either of those, the tuning context changes as expected, but the RX1 speaker is disabled and RX2 is enabled, so I cannot hear the DX, and have to enable the RX1 speaker and disable the RX2 speaker again.

Same thing happens if I use RX2 and RX3 for transmit and receive.� When I click to change tuning context to another RX channel, the speaker for the selected TX channel becomes enabled and all other speakers are disabled.� This happens whether I click on the selected TX channel or one of the RX channels.

Is this correct behaviour? It would be much easier if there was no effect on the speaker settings when changing tuning context.

Hi Neil

I have the same opinion as you, SW2 is not smooth to operate when it comes to split or RIT operation. I do like this:

1. Use RX1 as you RX VFO.
2. Use RX2 as you TX VFO.
3. Tune around with RX1 until you find someone to QSO with. I usually tune around�with Lock to CF disabled.
4. Click ->CF to get the RX frequency to the center of the display.
5. Click on yellow RX2 button.
6. Click ->CF to align RX1 and RX2 (the TX VFO) on the same frequency (center of display).
7. Click on the red RX1 button.

Now you have RX and TX frequencies aligned, TX is fixed in the center and RX is free to tune around. This scheme is how I solve the problem but it is very awkward and makes the DUO/SW2 experience less enjoyable.

t last thanks to David Price's Help all is now up and running.  A thought. I would have expected that files and information that are essential to get the kit working might rate a mention in the setup documentation.

Has anyone any ideas on fitting an amplifier to the fdm. I originally thought I would use my TS 2000. Any pros and cons.

Thanks again for the help folks.  Bob G4WHX

Try opening the virtual audio cable application and adding additional audio cables to the default starting point of a single virtual cable . These should then be available to assign to the required rx/tx slices in SW2 .

For some reason he deletes or renames the file on his disk later.
Now when SW2 ist started a System.IO.FileNotFoundException is thrown.
I can imagine this is annyoing for some users.

Either skip the error or show a confirmation dialogue "File not found".

OMG!
Instead of using the 0xc9 command i was using the 0x01 command!

Re: SW2: working split - help please (long question sorry) WISH TO ELAD TEAM

Because I want the RX and TX VFOs to be independent. I usually work split and use one VFO for the TX frequency (fix, not changed during the QSO), and the other VFO for RX. The RX VFO is adjusted, if necessary, during the QSO to get a nice signal form the station I work. If I just click on the TX button on the RX I use for tuning around I will not be able to independently adjust the RX frequency.

Re: CAT protocol problem with fdm-sw2

Richard Langley
 

When I wrote a Python script to automatically log the S-meter values on a particular frequency at specified time intervals, I found that I had to first send a command to set the LO frequency and then a second command to set the tune frequency. I also had to be careful about the decimal frequency conversion to a string of hex byte values (to which the CAT command was appended) and then into a byte string​ and then into a byte array, which was sent out the virtual serial port. Might be an easier way to do it but that approach worked for me.

Hi,


the FDM-SW2 use the CAT protocol of YAESU FT-897, that do not allow resolution down to 1Hz for frequency above 100MHZ.

For more accurate frequency setting I suggest to prepare for the TCP/IP server. Maybe tomorrow we will release new FDM-SW2 release with some corrections.
