My Power out with 3080 fitted and mod kit

[m0bmn]

HI

I have the 3080 module fitted in my KX1 and I have already done the power
mod

With the display reading 13.5v I get the following outputs

 

All power outs measured using the elecraft DL1 and a good Calibrated Fluke
Meter

 

80m = 3.74W

40m = 4.14 W

30m = 4.74 W

20m = 3.12 W

 

Running of nicads I get (7.4Volts on display this morning)

 

80m = 0.88 W

40m = 0.94 W

30m = 1.18 W

20m = 0.76 W

 

I know the power output is a little high on 13.8 volt bench supply (13.5v
after internal diode) but I only want to use this radio out and about where
I will

Be running on Battery rather than bench PSU so I am not to worried and main
bands of operation are 80/40m

 

All the best and I hope this helps anyone thinking about doing the power
mod,

PS I was  ½ - 1 watt less on all bands at 13.8V supply before the mod.

Hi Paul,

These levels are all fine. You could get more power out on internal
batteries if you used Lithium AAs (1.5 V), but of course that's a lot
more expensive than using rechargeables.

Makes me wonder how long it will be before there's a high-endurance,
reasonably-priced 1.5-V rechargeable AA to replace under-performing
"rechargeable alkalines." That's got to be the holy grail of the
battery industry.

73,
