At present, I am experimenting to see if I can omit the last audio stage. There seems to be plenty of spare audio. Being a DSB design, it is inherently 3dB down in sensitivity, but that has not been an issue hitherto.

Every few weeks I try to give an update on activity levels on the narrowband transponder on Oscar 100 using the on-line SDR at Goonhilly Down. I looked twice last evening at times that would have been European Sunday evenings.
My impression was that activity levels were quite low with plenty of space.
One of the things now possible on my new web pages is embedding. This has allowed me to add a grabber, so you can see what I am doing on PSKreporter maps. I think you can change the menus. Certainly I can. At the time of writing, I am looking at the last few hours on 10m FT8 RX.

As much as I like the occasional fry-up, even I would struggle!
Some would be very much against this.
Ivermectin seems to have anti-viral properties against Covid-19 in helping to prevent serious illness.
Some governments (Goa in India and Ireland) are recommending this very low cost drug as a prophylactic. I regularly watch the YouTube channel of Dr John Campbell and he is puzzled why this is not being widely recommended. He always gives the source of his data. I recommend you check this out.
Always seek the medical advice of your own doctor!
For the last hour or so I have been on 10m FT8 RX with the tiny indoor loop. It is now 1210z and so far 92 stations have been spotted.
UPDATE 1327z: 120 stations spotted today so far on 10m FT8 RX.
UPDATE 1358z: 132 stations spotted today.
www.g3xbm.co.uk is now pointing to the new site. If there are any issues or you notice wrong pictures or errors, please let me know ASAP. For a while things may be wrong. Overall, things should be at least as good as the old site finally.
You can see what I am spotting on PSKreporter.
As I mentioned earlier, I reckon this loop (the old Whizz Loop) is probably 10dB down on an external dipole. I hope to get a 10m dipole up this week, possibly with a 6m dipole too.
UPDATE 1914z: 185 stations spotted today on 10m FT8 RX.
One of the pleasures of Cambridge is gliding along the back of the colleges on a punt on the river Cam. Many prefer others to do the punting...
