Hi Marco, Roger and LF

 

I am replying to both in this mail because I gu= ess have started something off topic on the wrong Forum.

 

Marco many thanks for the suggestion. I may have to= go down that route if I still have problems make something work. So thank= s for your endosement of Spectrum who I know make a good transverter.= Ok about DL permits on 4m I didn't know about that. It's a good band ofte= n opening during the summer. On FM I have worked stations from the ol= d YU area S5XX (?) fully quieting signals just like locals. Get that permi= t again Marco and see you on 4m.

 

Roger yes it was funny seeing your mail co= vering 4m at a time when I have been struggling with that very issue.

 

And ok about LF, there is nodoubt that more activity= would be welcome as Mal says and we should try and do more. I know= you do a lot to publicise it. I think the trouble is we are few and sprea= d thin across wide ranging bands that need a lot of effort to achieve good= results. The result is that some bands like 500 get neglected while the= focus is on, say 8kc/s.

 

I pledge to do more!!

Hello Pete,

I was lazy and bought a ready to go 4m transverter= from a company in UK http://www.spectru= mcomms.co.uk/amateur.htm#TRANSCEIVE_CONVERTERS

I found the transverter good and cheap. I did many= MS+ES QSO with a special permit as DI2AX in 2009.

Hi Mal.

G3XIZ continues to improve his st= ation and has been copied at decent range on DFCW this weekend. Others, li= ke me, are finding out more and more about through-the-ground VLF communic= ations and are regularly copying UK and European stations on 8.97kHz by ra= diated DX. You've only to look on the news page of the Sub 9kHz Amateur Ra= dio website to see just how much is going on on VLF. See https://sites.google.com/site/sub9khz= /news

Certainly 10m has been very good lately, with WSPR repor= ts from around the planet with my 5W (or less) and a small wire halo anten= na. 6m and 4m Es DX is also about to start and I'm hoping for some QRP DX= on 4m with my homebrew transverter. See http:/= /sites.google.com/site/g3xbmqrp/Home/4m_transverter.

In my view= it is not either/or but all and more. 

Good luck on whicheve= r end of the spectrum you experiment Mal.
