Kenwood TS-2000 tips and tricks

Birdie

The Kenwood TS-2000 has a strong birdie (false signal) at 436.800MHz. This is the 28th harmonic of X400, the 15.6 MHz TCXO.

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.

Internal TNC

Kenwood TS-2000 internal TNC UNDOCUMENTED COMMANDS:

PASSALL ON 

SOFTDCD ON

The effectiveness of SOFTDCD doesn’t match a “real” external TNC–the TNC still relies on the hardware squelch. This means that the internal TNC may miss packets from mobile/portable devices with fluttering signals common to VHF/UHF.

fix no TX with internal TNC

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).

This is ONLY effective when the station you desire to communicate with can receive while transmitting. 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 receive.

Satellite Mode

The satellite 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 -1.0 kHz Doppler shift on 146 MHz will be about -2.99 kHz on 436 MHz, and so on.
