8-Some comments

Equipment at FR5DN :

On 2m:
In "beacon mode", 70-80w out into 17el F9FT-13dbd yagi at 6.5m above ground.
Old PC dedicated to the 2m station for digital modes and AIS receiver (modified FT-2500M).
For qso, i can use up to 120w out max in shack
Mast mounted LNA with BF981 feed through coax, no measurement on NF.
Coax is a low loss rigid coax LCF12-50, with some ecoflex 10.
I use separate TX and RX lines, which make things much more flexible, RX line is standard RG-213.
RX is Kenwood R-5000.
TRX for beacon and qso is dedicated Kenwood TR-9000.

Again, these qso are in reach of medium to small stations for sure!

On 70cms:

I run a single 21 el yagi at 9.5m above ground.
Low loss coax, mixed length of hardline 7/8 and some length of lcf12-50 and LCF14-50.
Power was 40w in-shack.
Mast mounted LNA 33db gain, 0.3db NF. Loss before LNA is around 0.9db!
RX is separated rx : LT70s converter with FT-990, 28Mhz IF.

The antennas used for the qsos:

Tks to All, and see you next opening !
