signals from ISS are very strong when they are in low angle passes but will almost disappear if directly overhead especially if you are using a vertically polarised antenna such as your bicone , glad to hear its getting you good results

another satellite you can hear at very high signal strength is NOAH 19 on 137.1 Mhz which produces a one second interval pulse tone and completely wipes out some of my local airband transmissions during passes

If you have an amateur radio licence, even a foundation licence, you can sometimes work them on 145.800. They use FM or digital modes like Slow Scan TV. I have worked them twice, one of those times whilst mobile & only running 10 watts into a 5/8th wave antenna, so nothing special.

Hi, If you really want to pull in more signals you could try making your own antenna like I did, thanks to users on here who helped me with the info needed, it was with this home made 3d bicone that I could receive iss with such good signal strength as seen in the you tube video above, it also now allows me to pick up licence free PMR radios from many miles away despite the PMR radios very low power. 75ohm good quality sky satellite cable is also great to use as it has very low signal loss. as you will see mine is far from nice looking but it works fantastic, since my last iss you tube video I have picked them up 4 times since, I was told to solder the joints which I have still not done but did cover them with insulation tape, still seems to be working as good as the day I made and installated it. See this link

145.800 is what frequency I receive iss on and since the video recording above have picked them up again on another 4 occasions.

I did once catch the Russian Zarya downlink transmissions on 130.167 , but it's very close to Signature Handling at Luton & Gatwick on 130.175 , so you hear that far more often (depending on where you are).
I reserve the right to ignore people who have made no attempt to the read the manual, and expect others to do it for them.
