Antennas • Re: DIY QFH Antenna troubleshooting

Your results are looking good. I have skipped a few posts but i registered to share my experiences with NOAA sats. I have found building QFH antennas to be very a temperamental exercise, especially when using cheap sdr dongles. The minimal interference shown on your last pic is to be expected. I suffer from huge drop-outs due to pager transmitters which are found at several frequencies some of which are very close to the sat frequencies. I used to get more consistency when i used a scanner to receive the analogue sats, definitely worth considering if your budget can stretch to a cheap scanner

Comment on KerberosSDR Preview: A 4x Coherent RTL-SDR for Direction Finding, Passive Radar and more by K9CQB

I see an Android phone showing a Line Of Bearing (LOB) display in one of your photos. Will there be an Android interface for this device? That would be so useful.

Здравствуйте, уважаемые члены сообщества. Хотелось бы попросить вас свежим взглядом глянуть на мою проблему. Если кто помнит, несколько месяцев назад я делал автономую станцию для приёма метеоснимков со спутников NOAA на базе raspberry pi. Проблема в том, что на выходе постоянно получается всякая фигня (её вы можете увидеть по ссылке. все принятые изображения автоматически падают туда). Менял антенну, менял местоположение, применял USB фильтр... всё бестолку. Только изредка проскакивает какое-никакое понятное изображение. Возможно, у кого-нибудь есть какие мысли на этот счет. Поделитесь ими со мной. https://www.dropbox.com/sh/fph8io6gc6rakqs/AABKa0Tu-IZoCJxMmdIpFZEVa?dl=0

sure!
You need just 2 thinks:
1) a HackRF you get a copy from China cheap
2) this Antenna: https://www.tindie.com/stores/hagster/
