displayed, then that info will go to the screen. No assumptions are made

Hi,
I am working on a project to plate the lamp reflector in an HP 5065A with
gold. The existing reflector is aluminum. What little I can find suggests
that in addition to some preliminary plating the layer just below the
gold should be nickel as the mirror operates at a high temperature (100

If you wish to do it yourself have a look at the products from Spa Plating
at http://www.goldn.co.uk/. I use their products they are really cool.
I have no other interest in this company or their Australian subsidury other
than being a satisfied customer.

Hmm, do you know if that is any good for goldplating homemade PCB's ?

You might check with a commercial PC board house. Back in the day we
demanded heavy Nickle plate under the Gold edge connector fingers on
the Telco product we manufactured.

First of all, let me start by saying that I follow the time-nuts mailing

Following a DDS with mix divide stages works great, but can be

Hi:
The HP 5100 provides extremely fast frequency transitions. It was used to
generate a 2 to 30 MHz sweep that was close to phase coherent. See:

No PLLs used, just arithmetic.
Have Fun,

Hi Marco,
That looks like a really nice receiver. It is a little numb as far as
sensitivity goes, but there are reasons for such. At those low frequencies
atmospheric noise will certainly be quite high. So, one way to to handle it is
to put the signal preamp out at the antenna, usually a
Good morning Marco
In the past I had best luck with a loop antenna using a copper tube (one
end insulated) using as many turns as I was able to run through it and tuning
it to frequency. One can also use a multi conductor cable and spice the
ends in such a way that it becomes a multi turn
To plate gold on copper requires the copper be first nickle plated.
Then the gold is plated onto the nickle.
Gold will not directly plate on copper.
