Dear friends Ham
I will count you a small history about some changes that I made to my
Some months ago I received from a friend HAM (regrettably it erases
the message and now I don't remember the e-mail, only save the
diagram) the diagram of as converting in the FL2100 the band of 10 meters
in 6 meters, for my that is very interesting because I only have
outpower 10 watt in 6 meters.
I began to make the simple changes to achieve that the lineal one to work
in 6 meters, The result at first sight was good, I entered with 10 watt
and the lineal one almost gave 80 watt, I was happy.
But I didn't realize that little by little the resistances R6 and R9 of
anti-parasite were been on heating until one day that burned and they
Very concerned and sad, several friends that I wrote them am from that
they have told me that makes some changes and up to now all the changes
I have made they have not given any result.
Here I explain to you the changes that I made looking for a solution.
When the resistances of 22ohm, burned I look for two same and I could not
them in any place, at the end they gave me two resistances similar of coal
47ohm, I put them to him and it also continued equally, I didn't follow it
using for not burning the resistance.
It also changes them the reel or crash that go in parallel with the
resistance and I put them a tape of copper of short size in form of U and
valves 572b became red to the 5 seconds of being transmitting, another test
that hise was to remove the resistances and to leave alone the reel
antiparasito and they become also red the 572B.
Now I don't have idea of as solving the problem.
I wanted you to help me, many people told me that wrote you that your
you have experience in those problems.
In HF bands works without problems.
I wait with a lot of interest your answer.
Thank you in advance.
