70 MHz FlexRadio MRF151G

By now those of you that follow my Amateur Radio meanderings
have probably realised the glacial pace that I operate/deveolp at.
After an out of the blue email from New Zealand about something
I posted in 2008 I have decided to get my 70 MHz setup sorted.

I built the 10 - 175MHz amplifier design from
Communications Concepts a few years ago but apart from proving
I could get 300 watts out of it I have never used it in anger.

Well that is all about to change! I have modified the old G3WPO
transverter I use on 4m to work with the amplifier. To drive the
transverter I have decided to use a FlexRadio FLEX-1500.

After my experience with the broken antennas a couple of weeks ago
I have decided to buy an antenna rather than make one, that way
if the worse happens I won't feel so bad about all the wasted time.
Currently I am considering an antenna from InnoVAntennas I have
heard good things about their range of antennas.

Keeping the theme of my laid back approach to radio I quite like
4m contests. There is plenty of time to chat with people (as there are so
few of them), propagation is better than 2m and occasionally you get
sporadic E openings. I just hope in the 2 years I have been away from
4m contesting it has not turned into another band full of pratts!
