Thread-topic: LF: O/T 4m Trnsvr PLAYED OUT

Hello Pete,

I was lazy and bought a ready to go 4m transverter from a company in UK http://www.spectrumcomms.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 Roger

 

Thanks for the URL to the 4m transverter. I have started to take interest in the band again. I have always been on FM. I have built several 4M converters but never had luck with the TX side. The last project I had a go at was one in RadCom a year back the Converter was all Mosfet which worked really well and I still use it. The TX side however was not a sucess mainly I think down to the mixer which was a diode double balanced design that I just could get to work.

So I may try the TX part of your circuit..... I hope you are prepared to answer questions later ... hee:-))

Hi Mal.

G3XIZ continues to improve his station and has been copied at decent range on DFCW this weekend. Others, like me, are finding out more and more about through-the-ground VLF communications and are regularly copying UK and European stations on 8.97kHz by radiated DX. You've only to look on the news page of the Sub 9kHz Amateur Radio 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 reports from around the planet with my 5W (or less) and a small wire halo antenna. 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 whichever end of the spectrum you experiment Mal.

Activity very poor over the easter weekend on VLF/LF/MF whereas all the other amateur bands were buzzing and some long haul acty on 10 metres.

Maybe it is time to abandon the lower frequencies and concentrate on the higher end like 10, 6 and 4 metres.

The results on VLF es LF es MF currently do not justify the effort, VLF acty from the UK especially poor in spite of several stations being permitted to operate on the 9 khz band.

Time for a change!!
