Two Instances of WSJT-X Running Simultaneously with Two Radios Two Antennas


I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

I am interested in using DM 780 for cw. I have tried it on the free HRD version, but it doesn’t decode fist cw very well. I know the fist is the primary problem, but I was wondering if maybe my rig/ computer settings might be refined to help.
I am running on a IC 7300 using the free HRD software. If there would be an advantage to purchasing the current version of HRD, I would be open to that.
Thanks for your help.

Are you running bandpass filters to avoid intermod in the two radios while operating simultaneously?

I just got my 7610
There seems to be a lot of floor noise in the 7610?
With no NR, ATT, or NB, SSB OR SSB DATA 1 and the AF gain at 12 and vol at 12’o clock. It is a loud QRM hiss.
My old FT 990 was quite the opposite, almost silent.
Is this due to the SDR technology, or maybe an issue with the 7610.
The noise reduction and filtration works great, but I would think a loud floor without an antenna attached would not be what you need?

Thanks as always

I did this, but ran into a problem. I use HRD to control both radios and interface to WSJT-X. However, after I opened the second WSJT-X, it overwrote the settings on the first instance, from COM9 to COM4. So, I had both instances listening to the same radio on the same com port. How can I get around this
