Re: JUMA PA1000, Please a hysteresis in the fan routine

Ok Marcel,

You mains switch modification looks good :D and I understand your point. I have kept my JUMA PA1000 always ON for years because it consumes only abt 5W in stand-by.

Re: JUMA PA1000, Please a hysteresis in the fan routine

You can download and install the new firmware from here http://www.jumaradio.com/juma-pa1000/JUMA-...

Re: JUMA PA1000, Please a hysteresis in the fan routine

Hello Marcel, You are right, there is currently no hysteresis in the fan ON/OFF control which can be annoying in certain ambient temperature. We have now added a hysteresis and a new firmware will be available soon. Additionally the main fan can be replaced with a silent model, see the instructions ...

Re: TRX2 vs TRX2A

Petr,

That's right TRX2 is only for 80 and 40 meter. TRX2A is for 160 - 10 meter.
In TRX2A there is additional RF filter board and different PA board.
