There are two basic settings as "Vo-IP Priority" and "Packet Priority".
The difference is as below.
"Vo-IP Priority" is good for noise and less distortion.
- [Good] = EchoLink(VoIP), WSJT-X, MMVARI, MMTTY, APRS1200bps. [No Good] = APRS9600bps
"Packet Priority" is good for Packet 9600bps by flat audio range. (depends on rig spec.)
- [Good] = APRS9600bps, -[Normal] = APRS1200bps, WSJT-X, MMVARI, MMTTY, EchoLink(VoIP)

Various plugs can be taken so as to meet your transceiver.
When you request a quotation, please let us know model name. We will suggest a proper connection.
IF you choose MiniDIN 6P or DIN 8P plug, conversion cable is available.
Various models can be used by using proper conversion cableodels. (eg. 6P to Hand-held)

What's the differerence?)
= HAMSTIR ST
Basic circuit design with dual USB Serial converter (COM port) and
passive audio input/output line by PC on-board sound device.
One of COM port is set as transmit timer (about 45seconds).
No other cable is required for PC and Rig connection.
This is not only simple but also better reliability (less contact points).

= HAMSTIR DX-R2
This has a photo-coupled circuit between PC block (COM/Sound) and rig control.
This is good for high-power operating.
DX-R2 can control two systems together independently as below example.
EchoLink (Rig1) and APRS9600bps (Rig2)

= HAMSTIR DX-R1
This uses the same board as DX-R2. But DX-R1 is only rig1 use.
And a part of rig2 circuit is used for PC CW-Keying (no additional cost).
This is especially good for high-power operating such as HF band.

If you operate HF rig aside even HAMSTIR is not connected, DX is recommended.
If you operate only V/UHF only, HAMSTIR ST is enough.
General use in less 50 watts O/P power, You can countermeasure the problem by ferrite-core etc..
