Hi Guy's n Gals.?

I recently purchased a FL-7000 & was wanting to interface it with my FT-847.?

Was wanting to know if anyone has interfaced their FT-847 with a FL-7000 & could let me know the pin-outs for a interface cable, or where I may be able to get one from.

Your help is greatly appreciated.

?Hi,

? I have both but there is no band change data from an FT847 but you do have standby for PTT. You cannot hook up the FT847’s PTT socket to the FL7000 without safely using a buffer. You just need a cheap optoisolated relay with short to ground. That goes to the STBY socket of the FT847 and the buffered side to the FL7000. The ALC “from memory” is -9vdc but might be wrong. I use mine straight though but let me double check that the -9vdc is in the range for the FT847 as I also have the VL1000 and that again has no option for band change other than use the F button in sequence and let the radio auto sense band from the signal.

? Other radios like the FT840 I have the band data but not the FT847.

I don't see why one needs a buffer to connect the PTT in the amp to a
FT-847. Per the amp manual the open circuit voltage is 12V and the
current
is 10ma max. The stby jack on the 847 is rated at 24V and 100ma.
Thus
the voltage rating is twice the needed voltage and the current
capability
is 10 times the needed current. I've used my 847 with several
different
solid state VHF amplifiers and never had a problem. Now if you were
connecting an old tube amplifier there likely would be a problem as the
amp
key line is often a negative voltage over 100 volts. Just read the amp
manual and check the max voltage and current rating required.
