2 m / 70 cm Band Plan Review 2022: Stage 2

NZART has completed a review of the 2 m/70 cm band plans.

The PDF to the right is a 3 page PDF with the proposed changes, also as printed in July-August 2022 issue of Break-In.

The reason for the review was to refresh the band plans with the various modes available today and to ensure that interference between different groups is minimised.

The review process was represented by operators actively involved with:

- Weak Signal/Long Distance/DX users (including Beacons, Meteor and EME)
- Weak signal digital modes (JT65, FT8 and WSPR)
- VHF/UHF Contesters.
- Repeater users both FM and Digital Voice (DV)
- Repeater users who currently suffer from SRD / LIPD interference.
- Satellite users.
- Digital (PC to PC) users (including fixed station licence holders and APRS)
- Digital voice users (including simplex)
- DV Hotspot users. (Both low power and external antenna high power users)
- Emergency radio AREC.
- Amateurs with 40 years’ operating experience and historical knowledge about these bands.
- ELG
- NZART Council

The current DRAFT band plans are ready for review by members as Stage 2 and be completed before Stage 3, the AGM in September.

Excellent discussion was exchanged to reach this Stage 2.

It was pleased to see how all these groups worked well together to future proof the 2 m/70 cm band plans by covering current, legacy and new digital modes.

One of the most difficult areas was with Digital Voice (DV) hotspots that are often budget engineered devices and were never intended for external antenna connections. Other DV hotspots operate with 25-Watt transmitters but lack any filtering or methods of limiting modulation noise output.

DXers have protection on the weak signal end of these bands with DV hotspot users encouraged to operate in new allocations.

I hope that the DRAFT band plans receive good feedback they deserve.

I look forward to seeing the new band plan in future call books and on the NZART web site for all amateurs to read and thereby enjoy their on-air operating experience.

Please send any comments, suggestions, and feedback to: VHF UHF Review Group vhfuhfreview@nzart.org.nz

2 m / 70 cm Band Plan Review 2022: Stage 1

NZART has commenced a review of the 2 m and 70 cm band plans to refresh them with the various modes available today, and to ensure that interference between different groups is minimised.

We are seeking volunteers/representatives that use 2 m and 70 cm from the following groups:

- Weak Signal/Long Distance/DX users (including beacons and EME)
- VHF/UHF Contesters
- Satellite users
- Digital (PC to PC) users (including fixed station licence holders and APRS)
- Digital voice users (including simplex and hotspot users)
- AREC

A member from ELG will also be invited to attend from a technical standpoint, and myself from council from a governance stand point.

It is expected the review should take three months, and be completed before the AGM in September.

The goal is to ensure the band plans accommodate the various uses without interference, and are robust to last into the future.

For Stage 1 we seek volunteers from the various groups above. If you would like to be part of the band plan review team, please email vhfuhfreview@nzart.org.nz with a personal introduction and overview of your area of expertise.

Please submit this no later than 5:00 pm of the 20 May 2022 to be considered.

Volunteers will be expected to reach out to their groups with the draft plans and provide feedback from the various groups to the review team during the review process.
