Orders & Prices

Following the sad passing of Dave G4HUP last year,  Dave’s family has agreed that the HupRF  kits and Website is transferred to and managed by SDR-Kits going forward.
As SDR-Kits, we already had close ties with Dave’s business, selling several of his kits in the past.
Our aim is to keep the HupRF website going in memory of Dave’s contribution to the Radio Hobby.  We will be offering some of the HupRF kits for sale shortly on www.SDR-Kits.net website,  starting with the  50 MHz and 70 MHz PAT boards.
Technical information on the HupRF products will continue  to be  available from the Huprf.com Website.


Please note that copyright of HupRF website has now transferred to SDR Kits Limited.  However if you use or make reference to Technical information taken from the Website then please continue to give credit to Dave G4HUP (SK) who as original owner published most of the  Technical information on this website . It is the decent thing to give Credit where Credit is due.

Kind regards

When you order, please check the out the following information from the HupRF.com Website to determine which version of the PAT board you need to order.

If your Rig is not listed, then check the Rig’s Service manual to determine what the 1st IF and optionally 2nd IF Frequency is.

  • Rig model:
  • Are you wanting IF tap or 2nd Rx function?
  • Do you want PAT SMD kit or an Assembled and Tested version?
  • Do you want socket or plug output?  (If there is a suitable hole at the rear of the rig to fit an SMA socket select the  GSIK kit, alternatively for a floating SMA cable output at the back select the GPIK kit)
