The Irish Radio Transmitters Society have just announced that Irish radio amateurs
The following was announced by Séan, EI7CD…
ComReg has just today published an amended version of the Amateur Station Guidelines
5351.5 – 5354.0 kHz CW, Narrow band Modes
5354.0 – 5366.0 kHz All modes USB for voice
5366.0 – 5366.5 kHz weak signal narrow band modes.
This allocation does not affect the availability of the existing channels centred on 5280, 5300, 5332, 5348, 5400 and 5405 kHz. Special authorisation is still required for these channels at an annual licence fee of €30. Lets hope for some more activity on 5 MHz to help our case for an increased allocation.

Up to now, Irish amateurs had to apply to use the spot frequencies

UK 5MHz Frequencies
Operation in the UK largely follows the conventions shown here. Exceptions are common as permissions in other countries vary, so QSOs on some frequencies may be found using any mode. Take care not to transmit outside the UK segments even if amateur signals can be heard as they may be coming from other countries with different allocations.
At WRC-15 in November 2015, the amateur service achieved a new 15kHz secondary allocation between 5351.5 – 5366.5kHz. This is not yet in effect and UK stations must adhere to the frequencies set out in the licence schedule, as shown below.
| Lower limit kHz | Upper limit kHz | Guidelines on current usage |
| 5258.5 | 5264.0 | CW activity, 5262kHz QRP |
| 5276.0 | 5284.0 | USB 5278.5kHz international use. EMCOMM CoA |
| 5288.5 | 5292.0 | Beacons 5290kHz. WSPR |
| 5298.0 | 5307.0 | All modes. USB 5298.5kHz, 5301kHz, 5304kHz |
| 5313.0 | 5323.0 | All modes. AM 5317kHz. USB 5320kHz |
| 5333.0 | 5338.0 | USB 5335kHz |
| 5354.0 | 5358.0 | USB 5354kHz |
| 5362.0 | 5374.5 | USB 5363kHz, 5371.5kHz international use. Data modes |
| 5378.0 | 5382.0 | USB 5379kHz |
| 5395.0 | 5401.5 | USB 5395kHz, 5398.5kHz |
| 5403.5 | 5406.5 | USB 5403.5kHz international use |
Please ensure out-of-band operation does not occur. Selecting a USB frequency shown here will ensure compliance and is largely compatible with allocations in other countries also. See notes 2. & 4. below.
Notes on the frequency table:
1. Upper sideband is recommended for SSB operation at 5MHz to preserve compatibility with other services. USB frequencies noted here are the suppressed carrier frequency.
2. Many countries have access to 5MHz and common international frequencies are indicated in the table. A good rule of thumb is to either use common frequencies such as 5278.5kHz, 5371.5kHz, 5398.5kHz, and 5403.5KHz, or keep them clear for others to use. Try to avoid frequencies which may cause interference to spot allocations outside the UK. For example, use 5335kHz and 5354kHz so as not to interfere with 5330.5kHz and 5357kHz, which are common to many countries but cannot be used in the UK. Some countries have already introduced the 5351.5 – 5366.5kHz band, but the current UK allocation only covers parts of this band. If in doubt, use one of the frequencies shown in the table above.
3. A band plan for the new 5351.5 – 5366.5 WRC-15 band was agreed at the IARU Region 1 Interim Meeting in April 2016. It will be incorporated into the UK band plan once the full segment becomes available to UK amateurs; at the moment, the USB frequencies 5354kHz and 5363kHz shown in the table above are within the SSB / all modes segment of the WRC-15 band. The proposed weak signal segment for very narrow band modes from 5366.0 – 5366.5kHz also falls within the UK 5MHz frequency schedule. The segments in red below cannot be used in the UK.
