Sorry but Mode C aircraft are not picked up. Most commercial aircraft have Mode-S or ADS-B nowadays.

Ok thanks for the quick reply , I work for a company that operates with Mode C at the moment thought it would be a good idea to have the Radarbox in the Ops office if it picked them up.

Unless you have an interrogator (like a TCAS for the office), the old modes will require several receivers to do multilateration.  It's complicated by the fact that Mode-A and Mode-C don't identify as such.  They are just bits, so you have to use a bit of logic to put them in the right table.

If you had 4 receivers, 4 antennas, you could probably get a 3D display.

It would be cheaper to equip your fleet with ADS-B and then you get all sorts of good data, like GPS position, altitude, velocity over ground, etc.

Cheers Steve , got new aircraft arriving soon , they aren't your airliner types but they may be equipped with mode S then.

Thanks
