30m SSB honor roll (hi)


actually (19.10.2014) we have 190 SOTA chasers listed in the 10 MHz SSB category,
while in the activators-category there is only 1 station listed on 10 MHz SSB.
Does that means the chasers are more nervous than the activators?
Of course I know these were only mistakes, but I´ve found it very funny anyway.

Have fun with SOTA!

There are a few parts of the world where SSB is permitted on 30 metres. You’ll certainly find at least occasional VK activations using the combination, and maybe South African ones too. Most of the chases will, however, probably have been ones where the chaser forgot to select the mode, and it defaulted… :wink:

Well, it could be…
This afternoon, while activating with Marcial EA2BDS our 2nd summit of the day EA2/BI-060, we had to stop the pile-up at 10 Mhz as 2 french operators (yes, they were giving their callsigns) started to transmit on 10.118 USB, seeming they were having some funny chat…

Hi Mikel and all,

30 m SSB is probably used more than 30 m CW here in VK. Some activators make a point of trying both modes on 30 m which is less used than the bands either side of it. This is partly because not all grades of VK licence can use 30 m. It is useful for contacts in the range 500 - 1,000 km during the day when 40 m and 20 m often don’t fill that zone.

There would be many more VK chasers on 30 m SSB than activators on SSB and/or CW.

If anyone wants to have SSB contacts on 30 m then come and take a trip to VK. SOTA activators always welcome - guided activations by local VK activators and we can help out with equipment.


As pointed out by Ron, 30 m SSB can be used here in VK, but it is not available to lower grades of licenses. Also those that can operate there may not have an antenna, I must admit to having hastily put up a 30 m dipole when some activators started using it.

It has helped get me enough points to qualify isolated summits in Northern VK2. Too far for QRP 40 m daytime propagation and too close for 20 m skip to the Southern populated states.

Hi all,

thanks for all the infos.
I know since the beginn of the new WARC-bands in 1979
some French operators are ignoring the IARU-bandplan on 30m.

It is interesting about Australian radio-amateurs working on 30m SSB.
On the IARU region 3-bandplan is no part for phone-operation whilest
on the WIA-bandplan there is a space from 10.115 to 10.140 Mc.

Anyway enjoy it and go ahead for the honor roll. hi

Best wishes and 73

Hi Fritz,

Echoing what Ron and Ian have said. 30m (10MHz) SSB is used in VK. In fact it’s very useful. SSB contacts at certain distances across the vast continent are clear and easy to read on 30m when not possible on 20m or 40m.

Also if someone has moved association, this could also give some positives - look up activator roll of honor 10MHz SSB All DL and you’ll see that I have activated 10 summits using SSB on 30m. - these were all VK summits.

A similar effect will happen if someone goes on holiday to Australia and activates (quite legally) a summit on 30m SSB, they will enter it under their SOTA ID which is your home call sign and again, you have some 30m SSB data coming up in the honour roll for the association that that person is registered with.

I personally would welcome the use of SSB on 30m across Europe, but if the national soceities have chosen to restrict the band to only digital modes and CW, it probably isn’t going to happen. I’m presuming phone isn’t banned in the licence conditions for a particular country of course.

As a user of data modes and CW I hope the authorities never allow SSB on such a narrow band as it would ruin it. We know what the QRM is like on 40m SSB in Europe, even though that band is now 200 KHz wide for most of us. SSB will never be permitted in region 1 on the 10 MHz band as it stands, and this has been raised several times before.

I would view this differently if the allocation was increased by a substantive amount. 30m SSB would undoubtedly be a useful band for SOTA participants, as it is for those of us who use CW and Data on the band.

I agree Phil. In places like VK the band occupancy is low enough that some SSB is perfectly reasonable. It simply would not work in Europe as there are so many users.

Perhaps we could do a deal to swap a perfectly useless extra meg on 2 metres for a hugely valuable 100 kHz at 10 megs!:wink:


Or learn Morse :sunny:

Actually an extra 100kHz at 10MHz would be nice regardless.

BTW some of us only get upto 146.9375 or so (can’t remember top of new band). Last time I looked 147-146 = 1 for all values of 147 and 146. Must be different down where the wind is blowing!

I know morse! Actually I memorised the code back in 1962, I’ve just never got up to a decent speed with it.

It doesn’t matter whether you approximate by calling it a round meg or 937.5 kHz (or whatever), they’re adding extra bandwidth to a band which has almost become a wasteland, for hours on end where I am you hear nothing but the CW identifiers of repeaters and some beacons. I find this particularly sad because there was a time when of an evening or weekend it was difficult to find an empty space for an SSB contact. It is said that HF is becoming less interesting to broadcasters, commercial and military users, so the IARU should at the least be pushing for extensions to the WARC bands.


Wideband stuff then. Move the repeater inputs or outputs to the new band and the allocate old repeaters frequencies with some new frequencis in chunks 125kHz wide with a split 1MHz up for high speed data. Use 64QAM for 6bits/Hz and 125kHz gives 750kpbs. Yeah, never happen as you can’t buy a YingTongBaofengIdleIpoh handheld for tuppence from eBay that does that and nobody builds/plays with stuff anymore.

I doubt that there would be much appetite for re-drawing the band plan to accommodate what appears to be a temporary allocation. By all means use the new segment for high speed data, but I suspect that there would be very few people interested in it. After all, what would all this data be about? How many bits does it take to say “your report is 59, my name is Brian, my locator is IO92bk”? Perhaps it can be used for digital TV, that might be interesting!


That was what the RSGB President suggested when I heard him speak a few weeks ago. But will it really be interesting? Who would put much effort into a temporary allocation?

Temporary is the key. Nobody will spend much effort if it isn’t permanent. And if we don’t make use of it then it will be taken away. Perfect Catch-22 situation.

Temporary and non-standard I would say.

Country allocations for 2m are “normally” 144-146MHz or 144-148MHz, not 144-147MHz. Temporary allocations are a pain in any case. I thought about getting onto 4m from here in Germany, but at the point that I decided which transvertor I was going to buy, the temporary period was finished.

In Australia the higher end of the band (146-148 is used for repeaters). Being still on 25KHz spacing the extra band space is useful. If the ACMA in Australia decided to take 146-148 away from the Amateurs, there would be difficulty (and high cost) to be able to squeeze the repeaters into the 144-146 section I suspect.

As I bought my current gear in Australia, I could operate in the 146-147 band while visiting England - but why bother?

Back to 30m - I agree SSB on 30m would only work if we could get some more bandwidth. The activity levels generally in Australia are a lot less. Here’s a question - if we keep 30m for digital modes only, does FreeDV qualify? While wider than most digital data modes, it is half the width of SSB. (FreeDV is Codec2 based digital voice).
