Hi; looking for Austron 2201A GPS antenna and manual. Please let me know; I
am interested in purchased one.

Fellow techies,
In light of all the horror stories on Ebay, I thought it would be a
Good Thing to call attention to a GOOD seller for a change.
If you ever deal with seller ID "toomanyamps," do so with absolute
confidence! I had bought from him what was advertised as 300 feet of
Jerry,
What reference and measurement system are you using to determine the frequency
values you are quoting ?

I just purchased an item from one of my "favorite" sellers on eBay, someone
who ripped me off in the past with a poorly described non working item (but
it powered up!) and ridiculously overpriced shipping and I swore I'd never
do business with him again. Only then he was doing business under the na

ok, so far so good.
Time for some parts.
I am thinking that Ill do the 10 with a crystal filter

Jerry has described the situation fairly well. You take pot luck, and
the Chinese supplier does not know which are which.
Out of four units I have, two are remote controllable, one is fixed at
(reasonably close to) 10MHz, while the fourth had no output at all. I've
since discovered that this last

Take a look at Beale's earlier post (be...@bealecorner.com) He's done
most of that for you.

Size and power look good so far.
Starting point for me is to run the little oscillators for a week and
see how they muster up.
If that looks good then maybe a few parts from DigiKey to build the filters

As we used to say in racing, "Speed costs money. How fast do you want to go?"
CRDs are not particularly expensive, especially when you consider the
performance and what it would take to achieve that performan

Never having used one of those, I'm thinking I'd need two mixers, a
10MHz bandpass filter and a 16 MHz bandpass filter. I'm guessing
A conjugate regenerative divider with 2 parallel (16MHz & 10MHz) low Q
bandpass filters should suffice.

I can't speak for anybody else on the list, but if there was an
inexpensive converter to get a good stable 10MHz signal from one of the
cheap 26MHz OCXOs, I'd sure be interested in building/buying one.

If you rephrase the question, it becomes easier: what is the drive impedance I
need to use to inject a signal at this point without getting reflection? 25
ohms because the two lines are in parallel at that point.
Now, however, signals coming from the other lines will not see a matched
impedance

There has been a lot a discussion on the list lately about using the
popular FE-5680A as a portable frequency standard and I have being

They are likely to be too noisy by several orders of magnitude for a
good crystal oscillator.
However they may suffice for something like a noisy ring oscillator or

Does anyone know what happened to the forum at
http://realhamradio.com? It has been in "maintenance mode" for quite
some time. I know that the other web pages are still available, but
the forum had additional information and discussion. Even if no new
posts are allowed, I hope the forum comes back.
