Steve is not the only one to give up. In the early days I worked over 30 countries on 137 Kcs CW and today there is only a couple of countries active.
What  does that say for LF and even MF has not really taken off. Activity seems to have fizzled out,  those that have deserted LF can be heard on 160 metres and other HF bands frequently DXING

I understand from his QRZ listing that Steve GW4ALG gave up amateur radio completely, something about not liking contests etc.

Hi Alan,
Yes, you're probably correct, but without knowing that 'detail' you coud easily misunderstand what it is suggested that unit could do.
Incidentally, it was GW4ALG, not 3. Steve says one of the reasons he gave up on 136 was the 'first RSGB repeater on the band' and it attracting 'pirates'. I have never heard of an RSGB repeater on 136 and think it a most unlikely band to interest pirates. Maybe I'm wrong, I often am!

Hi Chris that unit looks rather like the pictures of Steve GW3ALGs
variometer (others made similar units....the lego remote control rings
bells) which has featured in  the LF Handbook and both editions of LF Today.
If so Steve used a modifieed KW1000 linear I believe which was capable of
putting out quite a lot of power. Steve ran a 20m vertical with the top 10m
supported by party ballooons when the wind was suitably low. If it was put
below his main fixed loading coil as an incremental inductor then it would
not have had to suffer such high voltages as at the main coil top.

Hi LF,
Need a variometer? Take a look at Ebay item 120636022163. The claim is this
item can cope with 'over a kW of RF' and covers 136kHz - I must say I have
my doubts! At least you can have a laugh at the 'amature' spelling and
terminology throughout!!
