I do not recommend the EasyDigi interface. The audio transformers will prevent the higher speed modes like VaraFM.?
?
I use a modified CM108 USB sound fob for my digital modes interface: ? $4.?
$7 with the added mini-DIN DATA cable: ? See the attached photo.?
How to build:???
(The COS connection is only needed for the AllStar application -skip for all other digital modes)?
Scavenge a mating male mini-DIN plug from an old PS2 extension cable https://www.ebay.com/itm/224029009071?
Note: The cord from a PS2 mouse is usually missing a necessary wire from pin 2 (GND).?
?
If you cannot solder, buy an assembled unit: https://hamprojects.info/dinah/?
??
?
Use the linux alsamixer or Windows sound (mmsys.cpl) to adjust TX and RX sound levels.?
??
?
Also, get a transceiver USB computer control cable:??Icom CI-V 3.5mm
??
??
fldigi, direWolf, soundmodem, ARDOP and Vara Winlink have added CM108/CM119 PTT support in their Linux and Windows versions.??For other digital modes like WSJTx (FT8) and JS8Call, use the CI-V cable and hamlib to command PTT.
Also, CAT7200 for Windows emulates the serial RTS or DTR interface for PTT.?

Remember to disconnect your microphone. The microphone element remains in circuit on the front and rear microphone? connectors on the IC-7000, and will pick up stray audio. When I disconnected my microphone, my repeated packet rate in Vara WinLink dropped to zero.?
