ADRCS Collaborates with TARPN on IP400 Project

The Alberta Digital Radio Communications Society (ADRCS) have announced that it is collaborating with the Terrestrial Amateur Radio Packet Network group (TARPN) to implement an audio band version of its OFDM technology in their Terminal Node Controller (TNC).

“Adding the TNC rounds out the vision of the supernode that we presented at the Zero Retries Digital Conference last September and extends the functionality of the IP400 network to conventional radios on the 2M, 220 and 450 MHz bands, without any modifications”

— Martin Alcock, VE6VH, founder of the IP400 project

“Adding OFDM to our TNC gives us a higher speed mode than previously implemented and practical experience with OFDM”

— Nino Carrillo, KK4HEJ, creator of the TNC

“... in addition it will give us access to proven KISS mode technology that will greatly enhance the utility of our existing nodes in delivering higher data rates for conventional packet radio applications on existing terrestrial networks”

— Martin Alcock, VE6VH, founder of the IP400 project

RSGB Contest Committees Looking for Volunteers

The RSGB Contest Support Committee, HF Contest Committee and VHF Contest Committee are looking for volunteers who can help organise, support and manage the Society’s contesting activities. While applications from experienced contestants are welcome, the committees would also be pleased to hear from radio amateurs who are new to contesting.

If you are interested in volunteering, please contact RSGB General Manager, Steve Thomas, M1ACB in the first instance, via gm.dept@rsgb.org.uk

RSGB Band Plans: Key Changes You Need to Know

The RSGB 2026 Band Plans were published in the recently released February 2026 edition of RadCom.

This year’s changes address a handful of key topics, including updates to the 5MHz band plan to emphasise correct operating, which comes in the light of out-of-band FT8 usage and Ofcom monitoring concerns.

Updates at 50MHz have been made to accommodate new repeater inputs, which use a wider 1MHz split, easing the implementation of their duplex filters.

In the 430MHz UHF band, provision for low-power ad hoc repeaters and some editorial updates have also been made.

As Band Plans change over time, please ensure you only refer or link to the current ones on the RSGB website and remove any older ones you have saved locally.
