Kenwood TS-2000 Bugs and Quirks

Birdie:
Note that there is a strong birdie (false signal) at 436.800MHz. This is the 28th harmonic of X400, the 15.6MHz TCXO. There are proposed fixes, not yet implemented.
This birdie interferes with the first 1/3 of AO-27 and SO-50 passes. Using Narrow FM and tuning away from the birdie helps greatly.

Kenwood TS-2000 Internal TNC

Kenwood TS-2000 internal TNC UNDOCUMENTED COMMANDS: PASSALL ON | SOFTDCD ON
Note: The effectiveness of "SOFTDCD" doesn't match a "real" external TNC--the TNC still relies on the squelch (ugh).

To help mitigate the "No TX with internal TNC" issue, you might try "S-meter Squelch (menu #19A)" to enable you to transmit when the received signal is strong and transmits constantly (such as packet satellites like GO-32).
Note: This is ONLY effective when the station you desire to communicate with can receive while transmitting, and you must manually turn up the squelch for an instant, then turn it back down so that the TS-2000 can receive the other station after the TS-2000 sends its data.

The Kenwood TS-2000 with internal TNC is capable of ARISS packet operations.
The performance of the internal TNC can be a little frustrating on recieve.

Kenwood TS-2000 Satellite Mode

Satellite TRACE:
The "TRACE" feature of the TS-2000 is ONLY useful in conjunction with computer tuning, since it does not account for Doppler shift magnitude increasing relative to frequency. For example, a -1.0kHz Doppler shift on 146MHz will be about -2.99kHz on 436MHz, and so on.
