Kenwood TS-2000

The computer can only update both main and sub frequencies either:

  • In receive mode, or
  • In transmit mode with SAT selected.
A special solution is required when the uplink (TX) and downlink (RX) frequencies are in the same band. When you start the TS-2000 you have an extra TX VFO option Sub+XIT which is only used for same band split operation (see below). When selected the Sub VFO is used for transmitting, Doppler correction is applied by adjusting the XIT value.

Cross Band

In normal cross-band satellite mode (for example transmit on 70cms and receive on 2m) select:

The TS-2000 must be in satellite mode so that the computer can update the TX frequency.
Be careful with the TS-2000's TF SET button, each time you press TF-SET the uplink (TX) frequency and the downlink (RX) frequency are swapped. So if the frequencies in Ham Radio Deluxe are the opposite of those shown on the radio just press TF SET once.

Same Band (Split)

An example is talking to the astronauts on the ISS where the TX frequency is 145.200.000 MHz and the RX frequency is 145.800.00 MHz. You cannot use SAT mode as this is only used for cross-band operation, so you use Split mode.

XIT will be switched on as soon as you check TX [X] updates. If you switch it off then Ham Radio Deluxe will switch it on again.
The RX (main) frequency on the TS-2000 is set to the correct RX frequency (satellite + Doppler correction).
The TX (sub) frequency on the TS-2000 is set to the TX satellite frequency; the Doppler correction is applied by adjusting the XIT value. When you transmit the TS-2000 displays the TX (sub) frequency +/- XIT so the frequency displayed on the TS-2000 is the correct frequency (satellite + Doppler correction).
When you start transmitting you may hear beeps from the radio - it takes Ham Radio Deluxe a few seconds before it detects that you are transmitting. When Ham Radio Deluxe detects transmit mode it stops updating the RX (main) frequency until you return to receive as the frequency cannot be updated by the computer while transmitting with SAT off.

Yaesu

FT-847

You must select SAT mode on the FT-847 so that Ham Radio Deluxe can read and set both the TX and RX frequencies. It is not possible to determine the state of the FT-847's SAT button so you must press the SAT button in Ham Radio Deluxe so that it shows SAT as being enabled.
In normal cross-band satellite mode (for example transmit on 70cms and receive on 2m) select:

The FT-847 must be in satellite mode so that the computer can update the TX frequency.
When in SAT mode the FT-847 takes a long time to respond to 'Read Frequency' requests - especially if tracking is on, as a result when you tune the FT-847 with the radio's tuning dial the displayed frequency will not update very quickly.

Other

The transmit frequency of some Yaesu radios such as the FT-817 and FT-857 cannot be changed while in transmit mode, so it is not possible to apply Doppler correction while transmitting. If you think your Yaesu radio can be updated while transmitting please contact the author.

ICOM

IC-910H

In normal cross-band satellite mode (for example transmit on 70cms and receive on 2m) select:

Sat-04.PNG

The IC-910H must be in satellite mode so that the TX uses the Sub frequency. If the bands on the radio are the same as Ham Radio Deluxe but reversed press M / S to switch the Main and Sub frequencies.
Because the IC-910H cannot display the same band on both Main and Sub Ham Radio Deluxe cannot update the frequencies unless the correct bands are select using the radio controls.
In same-band mode:

A few notes:
  • The TX mode is not updated from the radio.
  • The software has to switch between Main and Sub so that the Sub VFO is updated, it is not possible to detect the radio's current Main / Sub selection so the radio operates in main mode all the time. If you press Sub on the radio you will see that radio switch back to Main as soon as the Sub frequency is updated.

Single VFO Radios

If you are using a single VFO radio such as the FT-817 then you use the same VFO for TX and RX. Use the TX (F1) button to switch between TX and RX. When you switch to TX the transmit frequency is loaded into the radio before it switches to transmit, when you return to receive the receive frequency is loaded into the radio after it switches to receive.

So the rule is: always use the TX (F1) button to switch between transmit and receive.

Frequency Resolution

The frequency resolution is set the 1 Hz for:

  • All ICOM,
  • All Elecraft,
  • All FlexRadio,
  • All Kenwood.

All other radios are set to 10 Hz. If you have a radio that supports 1 Hz resolution and is not in the above list please contact the author.
