Buyer Show

XV analyzer a little more than 2 showed, but in fact it is less, in the end I will explain why. FM when receiving a weak signal: RHD 771 signal/noise ratio 50/50, Discoverability is bad 35/75, have to listen to understand, more noise. N02 S/sh 75/25, disability 100/0. Listened to railways at 153 MHz, at the window (the window exits 90 degrees from the signal source) RHD 771 and nan02 accept. I leave the window RDH 771 noising once opened, on the N02 everything clearly. Even further RHD 771 does not catch, N02 takes, noumoab opens. Distance to railway 20km. At 444 MHz N02 is slightly inferior to RHD 771. Does not fit, continuation in the additional review. 13 Apr 2020 14:23

Additional Feedback

From the generator to the regular sent a signal, at a distance of SDR, connected rhd771 then N02, all in the photo. FM 104,2 MHz is a radio station signal. for XV: when connecting to the XV radio station, the meter readings were 0,5 less than on the analyzer. The body, hands, the position affects everything. Shorter: the correct position of work from the radio station, it is, to keep at the level of the head at a distance of about 20 centimeters, the antenna strictly vertically. The antenna N02 is set to comply with this condition. respectively ceb: 138mhz-1,05/140-1,05/142-1,06/144-1,15/146-1,21/148-1,32/150-1,5/152-1,6. 420mhz-4,1/430-2,2/435-1,99/440-1,8/445-1,7/450-1,68/470-2,8/480-4,8/490-7,5/500-11,2. At ccp-2 power loss 10%. when connecting one counterweight 46 cm at an angle of 90 degrees by 144.5mhz on the last photo. 444 readings do not change. retevis antennas are good and especially in terms of setting. small gap when installing on the walkie-talkie.
