Hi Roger

Thanks for=A0the URL to the 4m transverter. I have=A0started to take inter=
est in the=20
band again. I have always been on FM. I have built several 4M converters=
 but=20
never had luck with the TX side.=A0The=A0last project I had a go at was=A0=
one in=20
RadCom a year back the Converter was all=A0Mosfet which worked really well=
 and I=20
still use it. The TX side however was not a sucess mainly I think down to=
 the=20
mixer which was a diode double balanced design that I just could get to wo=
rk.
So I may try the TX part of your circuit..... I hope you are prepared to=
 answer=20
questions later ... hee:-))

Hi Mal.

G3XIZ continues to improve his station and has been copied at decent range=
 on=20
DFCW this weekend. Others, like me, are finding out more and more about=20
through-the-ground VLF communications and are regularly copying UK and Eur=
opean=20
stations on 8.97kHz by radiated DX. You've only to look on the news page=
 of the=20
Sub 9kHz Amateur Radio website to see just how much is going on on VLF. Se=
e=20
https://sites.google.com/site/sub9khz/news=20


Certainly 10m has been very good lately, with WSPR reports from around the=
=20
planet with my 5W (or less) and a small wire halo antenna. 6m and 4m Es DX=
 is=20
also about to start and I'm hoping for some QRP DX on 4m with my homebrew=
=20
transverter. See http://sites.google.com/site/g3xbmqrp/Home/4m_transverter=
.

In my view it is not either/or but all and more.=A0=20

Good luck on whichever end of the spectrum you experiment Mal.
