Quoting: M Haggarty
Please can you indicate for each of these receivers (and also for the STRONG SRT6420 TNT SAT Receiver for TNT Sat Freeview) whether they have RF in and RF out sockets?
STORNG TNT BOX, TOPFIELD TF5050 and XSAT CANAL boxes don't have RF inputs or outputs
ELECTRON and TOPFIELD PVR5400 (Canal Anytime box) accept RF looping (inputs and outputs)
You can use a modulator for receivers that do not loop RF signals, or use a VCR box (most VCRs have Modulators built in for accepting 2 or 3 scard signals -tricky solution but works)
but best to use a receiver with RF built-in
