Yes - the antenna was connectd in both images - sorry if that wasn't clear.
I took some time today and took equivalent pics in several configurations with both firmware versions, placed in roughly the same location.? I am attaching them - hopefully the filenames are self-explanatory --?
with antenna (multiples with different marker positions), with NO antenna, and with the 30Mhz cal output turned on.
The levels for the 30Mhz signal were:
FW1.1-52: -25.4 dBm
FW1.3-265: -25.0 dBm
I was running under the assumption that those were real FM signals, as the high peak (old firmware) was at about 95.7 MHz (which is a local FM broadcast freq).? I also found that when I brought the TinySA outside my home office/work area peaks on the right end settled down a bit.? There is a LOT of stuff in that office (3D printer which was actively printing), multiple PCs, LED lighting, IoT stuff, etc.
Two additional "newb" questions on this:
- What does the 'afrgnb' represent between the LOW annunciator and the FW version on the display?
- I noticed a difference in the display output between the two firmware versions (yellow top text, and one showed a prefix of '1T' and the other was '1R').? Is this a sign that I may not have had identical settings between the pics?
