Before putting my money up front for the first run of K4D I need to know what
is the dynamic range
of the K4D RX at 2kHz spacing. K3 is 105 dB and K4D? If it is 20dB lower than
K3 than it would be 85dB-correct?

Geoff,
You would need more like 35W amp.

Olli,
Would adding a low gain broadband linear amplifier between the KPA500's
input and the "10 watt driver" be a useful alternative to modifying the
KPA500?
I assume that during receive this amplifier would have to be bypassed.

Interesting. I have build 600W amp with four Motorola MRF150 transistors and I
can easily
get 600W output with 7W input. This was tested with input attenuator removed.
Are those Mosfets in KPA500 that much different?
I also would like to purchase the KPA500 but only if I could get 15 dB gain.

To me there is no difference between 3.30 and 3.41. Same low freq. response.
However, for my needs it is OK. Yes, I'm adjusting shift and width.
There is one problem with the new 3.41- the DSP high pitch noise level is
higher (3dB or so) than with 3.30.
Condition: RF gain at 12 o'clock AF set
Went back to 3.30 and LOW FREQ resp. is about the same.
Anybody else?

Lyle,
So, with SSB signal S9 and noise S2 with NR= F1-1 signal shouldn't drop to
much??
SSB signals always drop about 3dB. Even signals SSB with good S/N.
I understand all what you are saying but how hard it would be to increase AF
gain when NR is engaged?

Can anybody explain to me why with NR engaged SSB signal drop's in volume
significantly. AF volume has to be readjusted every time the NR is turned ON

NR is on F1-1.

Anybody noticed the TX SSB audio losing high freq.
This happens occasionally when K3 power is turned ON. Than I switch K3 power
OFF and than ON again and audio is fine.
At that point I have to readjust MIC gain UP or DOWN.In my case from

computer sound card. I was using VOX or PTT.
At the start of transmission the output power of the
K3
would jump to 50W. However the power of K3 was
adjusted to 25W level. So, K3 would put out 50W at
first and than quickly go back to proper

is only 4 Watts with distorted audio (power output set
