Digital Mode data cable
Question:? have you made a cable for digi modes yet?? the Lab 599 website has some diagrams for making your own cables and it shows a 10uf cap inline w/ the audio in side.? did you do this?? if you dont have that size of cap handy, would you think you could use a smaller or a larger cap?
?
Also, do you have?any advice on FLRig and WSJTX?settings to make it talk to the rig?? i get receive reports on WSJTX?via FLRig using the Kenwood TS-990 settings, but nothing on the TX out side.? i get the rig to go into transmit via the USB CAT cable, but no signals make it out of the antenna.
?
just thought i'd see if you have figured this out & are willing to help out. 73,? Matt, KG8TRS |
I use the Kenwood TS-930 as my rig definition and it works much faster than TS-990. I have made several cables. I did use the capacitor?as I have tons of new parts and wanted to make sure the TX audio was isolated no matter what sound device I used.

New to Ham radio and working/soldering components in general.? I'm looking up 10uf capacitors and getting dizzied by the different types.? I'm assuming (and I know what the first 3 letters of that word are, so bear with me) I would need a something rated at 15v to do the job, or am I wrong?? Should I go with something like this ()?? I just got my TX-500 in yesterday and I'm eager to do some digital with it!

Again, I'm new at fiddling with electronics.? Two more questions...
To install it, do you need to snip the audio cable and solder each end to the capacitor, or just cut away enough shielding to solder the ends to the cable? I'm under the impression an "inline" capacitor is able to be used in place of the one you linked, is that correct? Thanks for the reply and input!? |

Well, I have not looked at the 599 connectors, but the capacitor will go in series with the signal lead. It can be placed anywhere in series. At either connector end, or somewhere along the cable, whatever is easier.
Depending on the cable construction, you might cut the cable to install it, or if the cable is not really shielded (not a good idea, but lots of the foreign cables are not) you can just cut and insert the capacitor in the signal path. Hopefully that helps ... Doug |
There is no reason to use polarized, other than cost of the cap.? On Sun, Apr 25, 2021, 7:02 AM Chris via <ad8f=[email protected]> wrote:

If a circuit calls for a polarized cap, you can substitute for a non polarized. It is just a matter of cost control when in design.? 73, de Steve W0ARK On Sun, Apr 25, 2021, 11:26 AM Chris via <ad8f=[email protected]> wrote:
