No Radar, missing targets

[Cojaken]

I too would like a clarification of what "No Radar" means. The manual says:

"ADS-B system is reporting that it does not know about radar traffic targets, or that it is
not receiving information from any ADS-B ground station (in this case, you may still see aircraft that
are equipped with 978 MHz ADS-B out devices via the ADS-B receiver). Although you are receiving
ADS-B traffic from other ADS-B equipped aircraft, you are not receiving all detectable traffic because
you are not currently in a radar service volume and ADS-B service volume. Thus, the traffic portrait
may be incomplete. "

My receiver is an AFS ADS-B Dual Band Traffic and Weather Receiver (US only) 74113.

I am seeing some traffic and ADS-B weather, so my assumption is that the receiver is working, I am in a radar service volume and ADS-B service volume (Class C airspace).

Why am I seeing "No Radar" please?

Typically, its that your aren't within line of sight of an ADSB tower, which can vary greatly by locale. In my area, I usually have to climb to about 3k to pick up the ADSB feed from the FAA and then that message will go away. You should be getting ADSB peer to peer traffic from other aircraft regardless of the RADAR status.
