Playing with sig gen function today on a Wouxun UVD1 HT.

Andy G0FTD All Messages By This Member #12985 I seem to use the sig gen function quite a lot with my Ultra. Today I was toying with my old Wouxun UVD1 on the FM broadcast band. The broadcast FM RX has always been a bit weird, but usable, but nothing special. I learnt that I could get exactly -100dbm of MDS out of it before the the rx died, at 108Mhz. Even 1 db below was unusable, much like the typical sensitivity of other RX's. But the difference here was the absolute cliff edge when a signal was below -100dbm. Other rx's are still a cliff edge, but hell the UVD1 was so absolute. Below that the audio was so terrible as to be awful. Sent for info only, just appreciating the Ultra's sig gen function. Messeed around with other HT's in my collection. For example my Yaesu VX7R on HF was about -100dbm also. As is my Tecsun PL880. But at least it as some AGC, unlike the VX7R. I very much appreciate the sig gen function on the Tiny SA Ultra. 73 de Andy

Anyone remember the HP3486C? toggle quoted message Show quoted text On Oct 10, 2023, at 1:54 PM, W0LEV <davearea51a@...> wrote: Yes, the TinySA Ultra could legitimately be termed an RF DMM.
