HI

Yes, we are reading. Very nice amplifier, thank you for posting your experience. Now, the question is more a bout the support of this amp over the long term ?

I don't know exactly but I doubt there is a true QSK in the PA1000. At best, a fast T/R delay.

Matti EXCELLENT !... I studied the problem myself because I thought that a slight change in the value of the components of the active fillter could reduce the bandwith. This is not an issue of the rig just a design choice. I see on you image that the change is more complex. I hope it is usable with ...

Frank I do have a TRX2A (without the Spur option because installation is critical) and yes, there is birdies but they are not annoying because they disappear very quickly. Now the new main board of the TRX2A includes the Spur reduction. Sensitivity is also good enough on 10m (I also have a K3), no ...

Adrian I loaded the firmware 1.2 b6, but when I want to click DISPLAY I get "adress trap"!" and I can not access anything. Reloading the firmware does not help... I can load and save configuration settings I can load but I can't save user settings I am coming from 1.10q Do you have a solution ...

HI Adrian, The build 4 works perfectly. No I don't think changing bands while in Split is important. I see that during computer control, this is permitted and this allows cross-band operation. Cross band is absolutely not useful but I don't think you have to change anything to equalize the VFO in ...

Adrian I sent you a direct message but in case of you don't receive it... With this new firmware, I have an "adress trap" error when I attempt to change the filter bandwidth (using the JUMA protcol). I was obliged to reverse to 1.010h to make it working. Also, the new band switch (with RIT button ...

I ordered one "out of stock" kit some months ago (VM keyer). Just ask if any...

Leo, TRX2 is very easy to align but you need at least: - a multimeter and (recommended) an accurate capacimeter for checking and sorting the values of the capacitors before soldering (I use a L/C Meter IIB), - a dummy load and a wattmeter (as usual), - a small and simple RF Generator : and XG2 ...
