I assume you want it on the actual control circuit, and not on the timer request input. Adding an LED and limiting (say 1k) resistor between pin 3 and 2k7 resistor would work. This put the LED circuit

I was looking to create my own interface with perfboard and liked the idea of a built in timeout timer as shown in Raspberry-Pi-APRS.pdf (

Just to be clear - the question(s) was the original post from Mikel EA2CW. *Mikel EA2CW* So, just to confirm: There doesn't appear to be a way to cause the radio to PTT through the SCU-56 cable. a)

Hi Rob, I'm not aware of rig control for the FTM-100/FTM-200 radios (it may exist, but if so it is not documented). I'm supplying PTT to the radio's Data Connector from a C-Media CM-108/109/119 based

I'm very glad to hear about people experimenting with new hardware, especially with higher data rates. Dire Wolf relies on the soundcard audio sample rate for the bit timing.? A new timing strategy

Thomas - you state I think the question at hand is "When using Direwolf as an external TNC, how do/did you connect pin 3 (PTT)?" The previous comments are to say that CAT PTT (like: PTT RIG 2

Hi Mikel, I don't have the Yaesu FTM-200DE but I do have a Yaesu FTM-100DR which is the predecessor version for the North American market (I believe the DE versions are for Europe). Looking at the

Hello Mikel, Though you say a COM port shows up, did you check in the Device control panel and it doesn't show an exclamation point? You might consider installing the *Yaesu supplied* Prolific driver

I did a quick review of the manual for the SCU-56 and did not see any mention of PTT. The DX Engineering website (where I download the SCU-56 manual) implies it has CAT control, so the function may be

Hello, I am trying to configure FTM-200DE as VHF TNC for direwolf Currently I am using: - Direwolf ver 1.7G for Windows - Windows 10 - Yaesu FTM-200DE - Data cable SCU-56 (creates COM16 on the PC) I

Hi Thomas, thanks for the clear explanation. You confirm the information that Direwolf "as? is" should be able to support connected communication. Unfortunately I did several tests with two stations

That was a very good summary of the tunable parameters and tradeoffs. A more detailed discussion can be found here:

Thank you Thomas. This is why I am subscribed. Answers like this are very educational. Thank you -- Paul AC1DW

Hi Giovanni, I know I'm late to the party and you already got Direwolf in Connected Mode working for you. However it seems that you didn't get a proper answer to this question: There is no simple

With a bit more research under my belt, my questions come down to: * If I have a simple FSK transceiver that has 3.3v or 5v logic level for transmit and receive, is it possible to interface this with

After additional reading, I believe buddy filter is wrong for what I am trying to accomplish; should be ! g/N1VTT-1 as I am trying to limit transmitting messages where I am the addressee. But, I am

Jumping in on this informative thread to see if anyone can assist with getting the correct syntax for FILTER IG 0 ((i/30/2/37.05/-76.41/50 | i/60/1 & ! b/N1VTT-1) | (b/AKQ*)) During testing I get

Thank you David, my experience with sound cards? tells me that Windows 10 behaves often in unpredictable ways, not limited to Direwolf. Maybe it's more an issue of how it deals with USB Codecs, but

understood! Excellent, everything is working perfectly now!! Lynn that you so much for helping me understand this as well as teaching me how it works!

So that would add a term of -s//a/D?? You can never go over the 3 parts for a single symbol filter term. Lynn (D) - KJ4ERJ - Author of APRSISCE for Windows Mobile and Win32
