Plug & Play Interface for Android Smartphones to Yaesu FT817, FT857 and FT897 as well as IC-703 and IC-706 radio’s
Wolphi-Link is an Android Smartphone to Ham Radio interface similar to the interface shown in the QST 5/2012 article. Wolphi-Link works with DroidSSTV, DroidPSK, DroidRTTY and Morse Decoder. It will work with radio’s which don’t have a VOX. “Audio in” and “Audio out” levels are adjustable. The interface connects with a 4 pin 3.5mm (both ends) to the Android Device and with a 6 pin Mini DIN (both ends) to the FT817, FT857 or FT897. The interface should work with other radios as well but the cable needs to be customized. For customized cables please contact us at email@example.com .
Important: The interface uses the voltage of the microphone pin of the phone. The voltage on the microphone pin is ussually used to supply an electred microphone in headsets with a voltage. The voltage varies from phone to phone. We measured voltages between 1.8V – 2.7V on various phones but it might be possible that certain phones have a lower voltages. If the voltage is lower than 1.4V this interface will not work but so far we are not aware of any phones or tablets which have a voltage lower than 1.8V.
Wolphi-Link will not work on first generation Nexus 7 tablet (2012 version). The Nexus 7 2nd generation (2013 version) works fine.
WolphiLink might not work properly if you transmit on VHF or UHF while having your antenna to close to your phone/tablet and WolphiLink. The PTT might get triggered by RF and would not release.

Attention international customers: Priority Mail Internation normally takes 6-10 days. In the past a very few customers didn’t receive the package within this time frame. This delay normally seems to be related to customs. Paypal will email you a United States Postal Service tracking number when I ship the package which will be emailed to you but the package can only be tracked within the United States. There is no way for me to track the package outside the United States. In other words it may take longer (sometimes a lot longer) for the package to arrive and there is nothing I can do about it and I can not be held responsible for lost packages.
