Received 433 Mhz foldable antenna in good packaging condition. ordered on 11 Jan & received on 2 feb in bangalore. Support from Tindie team was very good . Though I request them for future orders them must give the option of different shipping partners so that customer can choose the option.
These boards are advertised as having "12.5/25 kHz bandwidth selection". This is not true: they appear to be preset for 12.5 kHz, as 5 kHz deviated signal drop out on voice peaks. Additionally, the CTCSS deviation is 1.2 kHz & the total voice+CTCSS deviation is 3.8 kHz. The squelch is too tight even on level 1, & if you program level 0 for squelch & CTCSS decode, the receiver stops working, so it is not possible to use only CTCSS (no noise squelch). Also, when programmed for CTCSS decode, CTCSS is only required to open the squelch. If CTCSS is then removed (such as when the desired station stops transmitting & there is another station without CTCSS still transmitting on the same channel), the receiver stays open. This is improper operation: the receiver CTCSS squelch should close as soon as CTCSS stops being detected.
