I finally had some time to assemble and test the new bought accessories to the FT-102.
Here's the result:
Now only some "minor" issues:
1- The HF antenna is broken (nothing to do with the radio tough)
2 -The accessories bough came with extended feet, the FT-102 didn't
3 - There are 2 birdies generated by the external VFO at 100Khz and 200Khz mark
4 - There's an offset of around 500Hz between the external VFO and the FT-102 counter (assuming one of them is correct, could not beat against WWV to confirm since the antenna is broken, see point 1)
How to address the issues:
1 - When I have time will fix it (not using this shack at the moment)
2 - Asked for the price of a pair of extended feet (got the reply while writing this; 5 GBP)
3 - Will investigate cable routing (signal is picked up on the antenna port)
4 - When I have plenty of time will adjust the thing
Another view of the setup:
Didn't tested the antenna tuner, assuming it's working.
Have a nice week!
