Right after sustaining the parcel and post in the newsroom, I made yesterday with the following test setup first tests in our workshop.
Notebook, Receiver: RadioJet 1102S, Antenna Switcher: AntennaJet ASM300 (Ant 1 Boni-Whip; Ant 3 Mini-Whip), 2 Measuring leads to the junction boxes, which were operated with their analog power supplies, 2x 10 Meters RG58 with 2x BNC (ready assembled), 1x telescopic fiberglass poles from Spiderbeams. The mast is about 4 meters high and 25 meters from the house and about 7 meters away from the workshop. The Boni-Whip was equipped with the original 10 cm long radiator.
Mini-Whip 147kHz. Signal -90db some noise.
Boni-Whip 147kHz. Signal -75db significantly more dynamic in the signals and less noise.
Mini-Whip: 177kHz; -80 DB signal, the signal is drown, the SNR is 15 db. 171 kHz can’t be seen almost. The intelligibility suffers from the interference (circled in red) but with the RadioJet Software you can notch this out.
Boni-Whip 177kHz AM, Signal -70db, SNR 20db, very good intelligibility of the signal, no interference in the Signal, much better Dynamics.
Mini-Whip 756kHz, Signal: -95db, SNR: 9db. lots of noise, bad intelligibility of the signal. Signal drowns, low dynamics.
Boni-Whip 756kHz, Signal: -80db, SNR: 12-15db. Much less noise, good intelligibility and dynamics.
Mini-Whip 9625kHz, DRM, Signal -100db; SNR: 30db. Despite the high SNR, the signal seems to interfered and the decoding snapped on only rarely.
Boni-Whip 9625kHz, DRM, Signal -78db; SNR: 36db. Immediate decoding without dropouts or sound fragments.
Mini-Whip: 21540kHz; Signal: -60db; SNR: 18db. Very clear and intelligible reception. You can see that very well in the waterfall.
Boni-Whip: 21540kHz; Signal: -69db; SNR: 20db. Noisy reception with less dynamics. The signal is drown.
Mini-Whip: 77kHz Zeitsignal; Signal -90db, der SNR ist 10 db. Lots of noise.
Boni-Whip: 77kHz Zeitsignal; Signal -88db, der SNR ist 15 db. More dynamics, much less noise. In the waterfall you can see the switching from the Mini-Whip on the “Boni-Whip”. The “Boni-Whip” significantly less noise.
Boni-Whip: 24kHz; Signal: -120db SNR: ??db. The signal is significantly smaller as on the Mini-Whip. Should there be a interference of a power supply or similar, then the Boni-Whip is insensitive about it. But a review is currently not possible.
Interim summary: In most cases, the “Boni-Whip” is better than the Mini-Whip. The tests are absolutely timely manner, proving the time code in the RadioJet software. , I will try the 21540 kHz again with a longer whip. Further tests will follow soon. A video is planned.
I’ve made more screenshots that I post here in a gallery without review. For questions and comments, please write me.
