Hi,
My first 6M rig was super regenerative RX and rock bound TX on a
rotatable dipole.
QSO with JA was like land line. When I was in 'nam, I used to hear
police VHF radio
traffic in Korea, Japan, Hong Kong almost every day with my Hammy
SP-600 RX..
when Es appears, watch out. The thrill of 6M. Have 6M module in my
Yaesu 736R but
no time to catch band openings.
73,
Tony, VE6CGX
