Re: TRX2A + Computer and PA100D
Hi, Daniel,
I presume that you wish to connect the Juma TRX2A + PA100D to a computer for logging purposes, or perhaps computer control, as the TRX2A can mimic a number of transceivers.
The 'problem' is that by connecting the TRX2A's RS232 port to the PA-100D you can no longer connect it to a computer, but indeed you can.
There are two methods by which you can have the PA-100D automatically select the appropriate band as well as control the TRX2 from a computer.
1. By setting the PA-100D auto-band selection to the FSENSE (Frequency Sense) mode then automatic band changes will still occur, thus freeing up the RS232 port and now the TRX2 RS232 port can be configured to mimic a Kenwood transceiver for example, or a Yaesu, and now you can connect it to a USB to RS232 converter and use any one of a number of logging programs or CAT control programs.
2. It is also possible to get the PA-100D to simply 'listen' to the data being sent from the TRX2A to the computer. For this you will need to make yourself a 'Y' cable. Connect the TX and RX data to the normal DB9 connector for the USB to RS232 as normal, but also take the TRX2 TX data to a 3.5mm stereo plug and wire the TX Data to the tip of the plug, and the screen to the ground. Set the TRX2 to use the Kenwood CAT mode where it emulates a TS-480. Set the PA-100D to the KX2/KX3 mode, and disable polling. The PA-100D will now 'listen' for the FA; VFO-A frequency string, and will respond by setting the band automatically. The normal CAT software constantly polls the transceiver with the FA; command requesting the frequency of VFO-A. The transceiver responds with a string of data such as: FA14175000; for example indicating 14.175MHz, and this will be interpreted by the PA-100D to select the 20m band.
I hope this is of help. Let me know how you get on, and if you require any further assistance.
