Due to the sudden passing of G4HUP business is currently suspended.

Change in Shipping methods

Due to poor reliability and delivery times of postal services in some places outside the UK, hupRF will no longer send products by untracked mail services.  With effect from 1st Feb 2017, all invoices for destinations outside the UK will have shipping prices reflecting these services.  We sincerely regret having to take this action, but the number of packages getting lost in transit is increasing.  See the News page for further information.

New Product – Switched Bias Tee

A new version of the DC Injector/VHF Bias Tee is available from Mon 9th Jan.  In the new version PTT switching is incorporated, removing the need to switch the DC voltage externally.  Details are on the Bias Tee page and prices are on the Orders page.

Since this increases the amount of SMD on the PCB, there will also be an Assembly Kit version, with all the SMD work completed.

Change of Operations

From 1st Jan 2017, hupRF will be operating as a conventional business, with normal 9am to 5pm attendance, 5 days per week.  E-mails and queries will be dealt with, and orders processed, during these times.

You can still place an order, or raise a query, at times that suit you – these will get responded to at the next working opportunity.

G4HUP products are still available, and all previous documentation is available in the Archive section, so you can still get the information to assemble that kit you bought in 2011!

Existing products will continue to be branded as G4HUP, but as new products are introduced they will bear the hupRF marking.  Increasingly, you will also see me marketing quality products designed by others, such as the DG8 144MHz Masthead Preamplifiers, which are by GM3SEK.
