Late June tropo

IMG_1245Having missed out on all the Sporadic E on 2 metres save IK8EVE (JN71) on 1st June it was good to be treated to some decent tropo. Starting on the evening of 27th June, on 2 metres I worked with my 25 watts all on SSB:

DF2WF   JO30

DM8MM JO31

DF0WD  JO42

DJ6AG  JO51

DK5DQ  JO31

On 28th June in the evening on 2 metres:

SK7MW  JO65

SM7XWX  JO65

OZ6TY  JO55

OZ1BEF JO46

DL3TW  JO44

DL2RZ  JO54

On 29th June in the morning earlyish

DK3EE   JO41

SM7YES  JO67 and incredibly strong signal.

On 29th June, SK6VHF (JO57) on 144.404 MHz was audible until about midday but faded as pressure fell so that when we were down to 1012 millibars at 1700 I knew the event was over.

I did try my luck on 70 cms with my one watt, and worked on 28th June:

SM6CEN  JO67

OZ9FW   JO65

So, a little bit of fun finding and working a little way away. I seem to have some advantage with sea paths, being near to the Thames and Crouch estuaries, and reaching mainly stations near the coast in Scandinavia.

New antennas and activity

After the trials and tribulations getting planning permission for my mast, and several setbacks since then I have finally got the antennas up and certainly working, at least on 2 metres and 70 centimetres. I have not yet fired up the transverter for 23 cms (I hope it still works after all these years), but I am operational on the two lower bands.

So how is the receive set-up? On 2 metres I can hear the Belgian beacon ON0VHF on 144.418MHz consistently just above the noise, but at least as well with my 7 element yagi as the Hockley shop down the road used to with their 20 elements. This is in flat conditions, even poor. I have a GaAs FET preamplifier for 2 metres and am using Ecoflex 15 feeder, but to my ears the readability is not improved by the preamp, which says a lot for the “front end” of the old FT290R I am using as the main transceiver for the moment.

Much to my surprise I can also hear ON0VHF above the noise on 70 centimetres using my 2 metres rig’s stablemate, an FT790R, also dating from the early Eighties.

Currently I have 25 watts on 144 MHz and have got into Lincolnshire with 1 watt on 70 centimetres, a distance of about 87 miles in flat conditions, and my report was 57.

There is a lot to come, especially when conditions may be more favourable.
