CAT connection between Yaesu FT1000MP+MicroHam_MK+DXLab+SPE_RFPA 1.5k

 

HI All. My problem is the following:
I have working at present time the Yaesu FT1000MP + interface MicroHam+DXLab_commander.
All the CAT ports are already in use.
I have added a SPE RFPA 1.5K but do not know how to connect it to the CAT bus.
Do you have any suggestion please ?

+ Use Commander's Secondary CAT Port to convey your transceiver's frequency to your amplifier; see

Configure your SPE to work with an Icom transceiver, connect the
CAT input to the CIV jack on your microHAM MK II (?) and configure
the CIV output (System Settings) to output Transmit Frequency.

tnx for the info.
I think I have already all the CATs in use:
MK_Cat1 goes to the TRX
MK_Cat2 goes to the Logger32
Commander Port1_Cat goes to MK_CAT1
Commander Port2_Cat goes to ColibriNanoRX-sdr
untill here all is ok.
Now I need a 3rd CAT to enter the SPE PA?and possibly a 4th CAT for WSJT
?
I have tried also the VSPE SPLITTER but it does not work.
?
To try your suggestion I have to change the interface from MK to MKII (it will take some time to find one)
hopefully it will "fork" the CAT stream from RS232 to CI_V and finally enter in the SPE_PA.
It should be tried an USB-RS232 converter maybe it would drive the SPE_PA.
I am waiting for a response from the SPE support too
Will let you to know asap.

+ You cannot have Commander and Logger32 controlling the same transceiver.

You *can* make up a "Y" cable to connect the SPE to the FT1000MP
in parallel with the computer *as documented in the SPE Manual*.
Note however, that such a connection is not necessarily reliable
with the ancient binary CAT protocol used by the 30 year old
Yaesu rigs.

GM Joe , thankyou again for the info and SAD abt the Y_RS232 cable not reliably working with "25" years young MP radio.
I will try to add an USB_RS232 converter and see if I can let it be recognised by the SPE_PA
and DXLAB_Commander.
