A good RF amplifier would make a poor IF amplifier.

I recall once reading something like:
"Most amplifiers oscillate,
Most oscillators wont".

Yes, transverters can be a bit of fiddle. In the 70s, I made one to go
with my 80 to 10m gear (on 14MHz), to get on 160m. It worked OK, but it
was all a bit of a fiddle if I wanted to swap back and forth.


I built a europa into an FT101 speaker cabinet ....I had to cut a bit off
each end of the circuit board.... build a chassis..... cut a front panel for
the europa meter.....stuck in a coax relay instead of the crappy bog
standard one...... painted the front panel morris oxford green.....stuck an
ft101 fan on the back..........oh yes and white leteraset .....and laquared
the front panel...I surprised myself with the result

sorry for the smelling in the above......So the Glasgow club asked me to do
a talk at their friday night meeting in the late 70's about it.......I
started : 'as I only want matching commercial equipment in my station
....ft101... fv101... sp101....I had to resort to building this to get a
matching 100w 2m transverter'.....that went down well....not...........still
got that chassis punch I used for the meter...never used it again...tee hee

Don't sell the punch, unless you can be certain you'll never need it
again.

I saw talk somwhere about the price of punches. I remember them being as
"expensive" forty years ago, but still within range. But apparently now
they have gotten really expensive. The best thing was to know someone who
had a set.

It wasn't uncommon back then to build accessories to match commercial
equipment. People would build things to match Heathkit, either buying a
third party cabinet (there were some that looked alike) and painting it
the right color, or buying a speaker that matched the rig, and using that.
Indeed, I remember various projects where people would stuff things into
the speaker cabinet, lots of room so long as you didnt' need many
controls.

I have no troll behaviour. I attempt to discuss the things and the ideas
that interest me but, unfortunately, a number of people, which figure
has included you, resort to abusive remarks in response to my attempts
to foment technical discussion.

Sure you do. Every time to get into a ****ing match with them you are
feeding their troll and being your own troll. If you don't like what
they say, just ignore them and it will all blow over. They only do it
to get you all wound up. And you seem to enjoy all the drama as much as
they do. So just stop all the back and forth and we will see that you
aren't a troll.

Nonsense.

And with your series of gratuitous personal remarks you are fallling into
the
trap of becoming the sort of person that you seek to criticise.

yes I was deluded about matching equipment in the 70's ...now I hate
matching equipment and frown upon hammy mens that must have it all sitting
lined up just like the sales brochure.....and I just knew I would never use
that punch again......at least with cars you know you will use your torque
wrench....torq sockets......impact screwdriver.....spring clamps.....hub
remover.... and oil filter removal cup wrench...etc

I am falling into one trap and that is responding to the tripe that you
offer instead of a conversation. There is nothing gratuitous about my
remarks. I am calling the shots as I see them without bias. You refuse
to even consider that you are as much a part of the problem as the
others are.

I won't continue to discuss this with you, as I have said my piece. You
can either improve your behavior or continue as you have done in the
past. So show some restraint and prove me wrong, or continue to blame
others for your issues and prove me right.

Gareth can't stop, causing trouble on Usenet is this perverse compulsion of
his. He loves the attention, even when it ends up with him in court or with
a copper's size 12 boot holding his head to the floor.
