UK 60m band(s)

At present in the UK, we have a number of secondary bandlets at 60m, but not the WRC 15kHz wide allocation. Our primary user is the military who seem to be in no hurry to change things.

Purely personally, I'd like to see the WRC allocation available in the UK as I find multiple bandlets very confusing. I know we have more power and plenty of choice, but I am a QRPer and having a common allocation would be better in my personal view. I fully accept my views may not be widely accepted.

In the quiet years ahead the 60m band will become more and more important. I have said many times before, it would be good if CEPT countries allocated a wider 60m band. I think we are happy to be secondary users.

60m (5MHz) band

More and more countries are being allocated the narrow WRC15 60m allocation. Many suffer from man-made interference on the lower bands from SMPSUs and similar. Nonetheless, this is an important new band that will be increasingly important as the sun gets quieter.

I have tried WSPR on this band in the past and must try again soon, although I have no suitable antennas, so use a random wire and my ATU.

In the UK we have not been granted access to the WRC15 allocation yet, so it important to stick to the bits we do have access to.

60m band

According to Southgate News, Malta has just released its new frequency plan that includes the WRC15 5MHz amateur band. This is only 15kHz wide, so we must hope for more later.

60m (5MHz)

It seems that several administrations have reduced the total 5MHz spectrum available and the power limits permitted when making available the 5MHz WRC15 15 kHz allocation. The RSGB, working with OFCOM and the UK military, has been trying to avoid this (see the GB2RS news last week).

Really I'd like to see the WRC15 allocation released in the UK too as soon as possible, but with the other "channels" still available. As a seasoned QRPer the power levels really don't bother me. 5W would be fine!

Many times we (I) take for granted the work done on our behalf by volunteers at the RSGB. A quiet thank you. You know who you are, HI.

More nations get the WRC 5MHz band

The Netherlands is joining the growing list of nations gaining access to the 15kHz wide international WRC15 amateur allocation at 5MHz (60m) although, you will have read, the UK will not be joining the list anytime soon. We have non-contiguous bands at 5MHz that allow access to more spectrum with higher power. Personally, I'd prefer a contiguous allocation and the power limits do not bother me.

No more 5MHz ....yet

On the GB2RS news today from the RSGB:

Somebody dragging feet?

"Amateurs in the UK have been very fortunate in having early access to 5MHz, with 5 spot frequencies 15 years ago and more than 70kHz of spectrum made available in 2013. This was a result of close cooperation with Ofcom and the MoD, who is primary user on the band. The UK currently has an arrangement that gives us more spectrum and a higher power allowance of 100W at 5MHz, however it does not cover all of the WRC-15 band of 5351.5 to 5366.5kHz. The Society played a very active role in the WRC-15 process and continues to work with Ofcom to gain access to all of the WRC-15 band, however this is not expected to change in the foreseeable future as there are on-going assignments within the band. The RSGB will implement the IARU Region 1 band plan for 5MHz within the segments allocated to us. In common with other Region 1 societies with allocations greater than 15kHz, we will recommend that frequencies within the WRC-15 band that are allowed under the UK Amateur Radio Licence only be used for international contacts, or for stations with no other option."

60m in the UK

According to the latest RadCom, the RSGB is still negotiating with OFCOM and the military to get the WRC2015 worldwide 60m allocation available to UK amateurs in 2017 in addition to the existing UK allocations.

Other bands WSPR or JT65?

As I am unlikely to be able to erect a better MF antenna before next autumn, I wonder what band I should use overnight on WSPR or JT65? 5MHz (60m) I can manage as I've resonated the antenna before. My noise floor is bad on 5MHz, but I should be able to TX (beacon) with either WSPR or JT65. I know 40m or 30m are possible (but little challenge), but in "quiet sun" years 5MHz (60m) is likely to be "open" more.

I may give 5MHz a go tonight. I have still to decide WSPR or JT65. As usual, I'd use 2W.

UPDATE 2008z:  I could not load my antenna up on 60m, so  have gone on 40m WSPR this evening and overnight.
40m WSPR spots this evening

UPDATE 2230z: Most spots of my 40m WSPR (2W) are from Germany. Best DX on TX was SA6BSS/RX (1059km). My antenna is far from ideal on 40m. It is very low.

Now Australia (nearly) on the 60m band

Southgate News reports that Australia is about be granted the new WRC15 15kHz wide 60m band. It seems that many countries are gaining access.

Eire and 5MHz

Thanks to Southgate News I have learnt that radio amateurs in Eire are gaining access to the WRC15 5MHz allocation right away.

See http://ei7gl.blogspot.co.uk/2016/12/irish-radio-amateurs-gain-secondary.html

"ComReg has just today published an amended version of the Amateur Station Guidelines in Document ComReg 09/45R2. The main revision is that the WRC-15 band of 5351.5 to 5366.5 kHz has been released with immediate effect on a secondary basis. No application or fee is necessary for this segment. The power is 15 watts PEP (12dBW) measured at the output of the transmitter or amplifier. All modes including digimodes may be used. The WRC-15 decision was for 15 watts EIRP and this will be taken up with ComReg. The Society recommends that USB be used for voice as has been the convention on this band and as used by the primary user and that the provisional IARU band plan be used: 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."

I have said many times that the 5MHz (60m) band will become increasingly important as the solar activity declines.

5MHz in Germany

My German is poor, but I think the Germans have been granted early access to the WRC15 15kHz wide band at 60m (5MHz).

I have said many times before, it would have been better if CEPT countries were allocated a contiguous 100kHz wide 60m band. 15kHz is good, but a wider band would have been so much better.

As the solar conditions worsen, the 60m band will become very important. As a secondary allocation, I am surprised that a contiguous wider band is not being allocated as many countries have daft allocations in channels, which differ around the world.

5MHz

Southgate News reports that the SARL is trying to get a 100kHz slot at 5MHz. I think this is wise. A larger contiguous band would be so much more useful than the 15kHz worldwide allocation that was granted at WRC 2015. I hope CEPT countries try for a 100kHz wide 5MHz band. It could happen that quite a few countries allocate a 100kHz wide band on a secondary basis to the amateur service. In the coming quiet solar years this could become an important band.

5MHz allocations

Several administrations have now granted access to the WRC15 15kHz wide amateur allocation at 5MHz. Eventually this will be a worldwide allocation.

In CEPT countries, I really wish they would allocate a contiguous 100kHz wide band. 15kHz is very narrow and I for one am confused by the multiple narrow "channels". A 100kHz wide band would be so much better.

IARU

See http://www.iaru.org/ .

The IARU is the "umbrella" organisation guiding the amateur communities around the world.

In region 1 I very much hope that a 100kHz wide 5MHz band will be allocated to radio amateurs in Europe despite a 15kHz wide band being allocated worldwide at WRC15.

There is quite a bit going on to persuade amateurs to adopt a new band-plan for 6m which involves relocating beacons slightly further up the band. It will mean more space for CW lower down, as for most HF bands.

Return to 10m and 6m WSPR

After another night on 5MHz (60m) WSPR where the best TX DX was again KK1D (5409km), I have returned to WSPR on 10m (100% TX, 500mW, randomised TX frequency) and 6m WSPR (1W ERP TX 20%, RX 80%). Later I may switch to the FT817ND on 10m so I can listen 80% of the time as well.

Staying on 5MHz WSPR

In the end, the "London" grandchildren have only just left for home, so I have decided it is too late in the day to QSY to 10m. Instead, I'll remain on 5MHz (60m) WSPR until tomorrow, hoping for some DX tonight.

5MHz WSPR overnight

Well, I stayed on 5MHz (60m) WSPR overnight. Best DX on TX was KK1D (5409km). In all, 40 different stations in 12 countries have copied me on 5MHz WSPR.  I think others are copying me better than I am copying them as my noise floor is quite high here. So far I have heard just 7 unique stations, all in the UK.  If I am going to use 5MHz (60m) in future years I need to reduce my noise floor on RX.

Later today, I shall probably go back on 10m WSPR.
 
We have our "London" grandchildren staying here this weekend with their mum and dad. They take priority.

5MHz WSPR overnight

WSPRnet sprang back to life this afternoon (I think). It disappeared sometime overnight after 0250z I believe. This eventually allowed me to see the best 5MHz DX last night on WSPR TX. This turned out to be a spot from AB4DF (6436km). There may have been others, but WSPRnet fell over, so I shall never know. I hope to be on 5MHz overnight, so let us hope WSPRnet works! My antenna is very poor and very low for 5MHz. I am amazed how far I got last night with 2W and this low, inefficient antenna.

UPDATE 2135z:  37 unique stations have spotted my 5MHz WSPR in just over a day. Probably more as WSPRnet was not working for much of the time. 5MHz is proving to be a very useful band.

5MHz WSPR - am I wasting my time?

With WSPRnet still not working I have no idea if last night's efforts were worthwhile or not on 5MHz. The chances are that no spots are/were reaching WSPRnet, so the last 12 hours or so were probably all in vain. If this continues I shall be forced to abandon WSPR, which would be a great shame as we enter the Es season, which benefits the higher HF bands, 6m, 4m and 2m.

5MHz through the night

Through the night I shall stay on 5MHz WSPR to see what happens. I am not familiar with the band so have no real idea what I should expect. I was quite surprised that my Par matched so well with the ATU.  So far the Icelandic spot remains my best DX on TX. I should try 10MHz sometime.
