Welcome to OneChipDesign !

*** HAMSTIR ST ***

Interface for FT8, JT65, PSK31, Echolink, APRS, SSTV etc..
No additional cables are required. Cables are wired to meet your transceiver.
When you order this product, please let us know your rig name.
For EchoLink operation, natural operating by squelch control can be done (DATA terminal model).
Hand-held transceiver can be used. For high power operation such as HF rig use, HAMSTIR DX is recommended.
Full photo-coupler conection separates rig block from PC block.

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)

Dual port by FT2232 FTDI chip inside.
COM-A is for normal use.
COM-B is for packet communicating. This port has a transmitting timer of about 45seconds.
After that, PTT is forcely turned off.

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..

Download basic setting for digital communicating(zip898KB) :
Most of pictures are Japanese, but the points will be understood.
This is the case of WSJT-X settings, but almost common on the COM and sound items.
Most of sound devices have a sound enhansment such as surround effect.
This digital processing makes bad encoding and decoding.
CAT and CI-V features are for rig controling by PC, not for digital cmmunicating.
If there is not a preparation for it, refrain from setting !
