>How do you operate QSK with that kind of setup ?
I don't operate QSK but I am sure there are QSK ways of protecting
preamps. This is a question for the QRO CW DX folks.

On those ICE preamps, check the small dipped inductors, because they
can blow open if the preamp is exposed to a high enough RF field. If
your preamp is on a rx antenna and you are transmitting with ham QRO
nearby that's enough to do it. IIRC powering down the preamp isn't
enough. It has to be b
Does anyone know the active element or have a schematic for the ICE 135B preamp
? I really like this preamp and bought it years ago (for about 50 bucks). It is
no longer working and suspect the FET (?) is blown.

I believe OH8X had one or more “hammers” mounted to their 160 Yagi to help
remove the ice buildup. Sadly their extraordinary effort recently fell victim
to winds and reportedly torque: http://dx-world.net/2013/oh8x-tower-collapse/

Jay, WXØB, of Array Solutions tells me that they are very close to introducing
products to replace some of the ICE designs no longer available.
The ICE 196 RF limiter and the 197 that adds a lightening arrestor, have been
redesigned to use Mini-Circuits RF transformers that virtually eliminate t
I found one of these in box of stuff. The printing on the label has
disappeared. Does anyone have one of these, and could you email me which taps
on the terminal strip are what impedance? This is a multi-tap beverage
transformer.

A few months ago there was a post that ICE is now:
http://www.morganmfg.us/
I asked about the ICE 196 and received this:
"Sorry, we are not currently supplying that product."
The interior of the 196 can be seen here:

Anyone have the specifics of the parts used in the ICE196 front end protector?
A picture of the interior shows two binocular cores, two diodes, a resistor and
two ceramic caps. The manual does not list any details, windings etc. nor can I
find anything web surfing.

Hi Scott,
I have been using the ICE 196 for about five years. I was
having problems with my Orion doing strange things (such as shutting
down0 because some of my Beverages are under my 80 and 40 meter wire

bands--no mo
