This is more like an ALC overshoot than a keying spike like in the IC-781
Especially noted when using a low drive Amp and several spikes will be noted
from key to unkey while in SSB.
I have noticed it since owning a 5K since 2008 almost 3 years; However have
seen it improved since intro of Beta 1
I have finally figured out how to make an entry into the Flex-Wiki!

I thought that Downward Expander (DE) is used to reduce background noise when
you 'aren't' talking.
When you are talking, the Compander (CPDR) compresses (attentuates) the voice
peaks and expands (amplifies) the voice valleys.

One of my favorite transceivers was the ICOM IC-781. It had a spike of 150
watts before the ALC took over. Quite a few low drive amps died due to this

figured out the problem and corrected it. It required swapping a

It might possibly show up on the scope function of the panadaptor
panel. Several of us had a pulse affecting RTTY tx a few versions
back, and it showed clearly on the 5000a scope function.

DX. That is what it is for. The Compander is to reduce background noise when
you aren't talking.

Just downloaded PSDR 2.0.19 RC1 on my Acer Aspire 1 with Intel N270 CPU 1,6
GHz and 1,48 GB RAM. To get 1024x768 resolution on the 8,9 screen I use the
freeware program A1Ctl.
Connected the FLEX-1500 to the PC and after some setup changes the radio
runs flawless on the tiny PC. No sound cracks
I have similar concerns while using my Kenwood TS480 transmitter
with my Flex 1500 receiver. Have tried it using a horizontal loop for
receiving and a vertical for transmit, with about 100' of horizontal
separation. The 1500 indicates a signal around -7dbm when transmitting with
the TS480
Tim, et al.,
I must admit to being surprised a few weeks ago when a tremendous crack of
thunder awoke me from my usual stupor. Normally, in the months from late
March to November, all antennas are disconnected unless I am actually
operating. And even then the door is often opened and the s
It fixes both sides. The opposite spur was weaker and less problematic
since it was lower than the image in every case tested.
Fewer than ten owners complained to Flex. It is fully realized how many

even out in the open.

I have done all that too.
When I opened my 8KW ICE arrestor it was all black inside. 10 kohm
resistor and the light duty neon lamp were gone. There is not prober
gas discharge tube inside unfortunately.
Yes I changed three or four of those PE4259s. All were in line with
RX1 Out BNC.
Timo,
The TSB41AB2 is your 1394 (Firewire) physical controller IC and is not on the
HRFIO board. The PE4259 are RF switches.
My first guess would be that your issue is not transmitting 100 watts with a
beverage nearby, but it is possible. I would suspect an EMP from a near
lightning strike or a pow
Last summer my Flex5k went deaf because of lightning. I have almost
everything protected.
Only RX1 OUT was not having lightning arrestor. There is not gas
discharge tube inside the radio too. So, my theory is that lightning
overvoltage got inside through RX1 OUT BNC.
