![]() ![]() The 15kHz filter setting is their botch attempt to capture the signals because its so off frequency, this gives a higher BER which means much poorer digital decoding.Ĥ. 15kHz is far too wide a filter for DMR, NX48, iDas, dStar, 6kHz is plenty wide enough. At HF, 5MHz, it drifts the opposite direction and has to be tuned -300Hz at 20 deg C which is 54.5ppm, 10 times out of spec.ģ. The DV10 has to be tuned +3kHz at 450MHz, +8.5kHz at 900MHz after about 1 hour at an ambient temperature of 20 deg C, it is supposed to maintain +/- 5ppm from -10 deg C to + 50C operating temperature.Ģ. However understanding the wish of higher frequency stability for a better receiving experience, we will work on the firmware to add a function which adjusts frequency depending on the internal temperature. With +/-5ppm, at 450MHz it might drift by +/- 2250Hz which is within official specifications. As the frequency stability is +/-5ppm, the drift you describe is unlikely, however understanding the wish of higher frequency stability for a better receiving experience, we will work on the firmware to add a function which adjusts frequency depending on the internal temperature. The reply that claims to from "our engineer" is pretty much the standard text that AOR Japan send out, that is very similar to what they emailed me 2 weeks ago.
