Re: Icom IC-9700 users topic

Here is yet another solution: inject GPS locked 49.152MHz AC-coupled signal into the the output of the X8601 VCTCXO without shutting it down. I have used 0.1uF 0603 for AC coupling and mini GPS clock - set at 49,152,000Hz and 8mA drive. VCTCXO seems to become either parasitic injection locked to ex...

Re: Icom IC-9700 users topic

FYI the 10 MHz logic output to the FPGA was constant duty and well behaved from 25mV ptp upwards. At 0.6V ptp, the duty cycle began to vary with input level, I would regard that is the maximum recommended level. That is, beyond the designers objectives. The radio seems to be just fine up to 3V ptp. ...

Changes from Version 1.10

Fixed an issue where the IC-9700 may hang up on a multifunction dial operation.

Re: Icom IC-9700 users topic

FYI Rob Sherwood Jun 11 #3174 I did some testing as to the effect of level into the nominal -10 dBm 10 MHz input. It will sync at -30 dBm, not that I recommend it. I fed in 0 dBm for quite a while, and it works fine. Also fed in +10 dBm, and the radio didn't complain. Considering the information pos...

I have uninstalled those drivers and installed the Icom supplied drivers. That has not fixed the problem. I have also renumbered...

WSJT USB Audio Sources???

I have never really persevered with WSJT before, as I have found it extremely user hostile years ago. And again now. I am trying to select the IC-9700's USB audio as a source, but this isn't an option. There is no problem with the 9700's USB drivers. I see both com ports (30 and 31 in my case). CS-9...

Re: Icom IC-9700 users topic

This part is interesting 'A small coupler PC board is soldered to the top of the TCXO can inside the IC-9700'. Any residual solder evidence from this 'mod' will no doubt void the warranty. The first few returns to Icom might slip through as warranty jobs, but I'm sure they will be on the look out f...

And another interesting snippet involving the always-on fan modification... which may become unnecessary, if the above is true. I have now got my IC9700 plumbed into my 23cm EME system. I have the 23cm output set at 12% (about 1.5W) and this drives the two stage PA to around 200W output. on JT65C I ...
