We had a Lennox Signature A/C - gas furnace installed 7/21/2011.
The gas furrnace is a SL280UH09V36B
The outside A/C unit is XC21-036-230-06
System has the "Icomfort themostat"
I was concerned about this because the last furnace we had came
with a solid state Tstat and it was unusable even with PI filters at the
furnace on all Tstat lines (Ferroxcube VK400-4B ferrites and 0.01 disc
ceramic each end ) - had to go back to an old Honewell mercury Tstat.
The Lennox Tstat has shown no ill effects whatsoever with no additional
filtering . I had it in the contract if any problem - they have a wireless
Tstat
system that would probably take care of it if any problem.
1500 watts all HF bands - 160/80 M inv vee about 15 feet above the
furnace and Tstat line and KT34 up about 45 feet above and to east
and 40 M rotary dipole at 50 feet .
Have not detected any RF noise from the outside unit.
I get carriers every 18 khz from the furnace blower variable speed control.
The contratct said "they would work with me" if any problems. I have not
pushed that
to any extent because they gave me a contact number at Lennox and that was a
total waste.
There must be someone somewhere at Lennox but this guy was not it , he could
not
find anything on RFI. My question was if they had any RF filters for the
furnace blower. .
I have probed around the furnace with an ICOM R10 receiver and its really
clean
except the 110 line into it and I am sure a good line filter will take care
of it. I told
then m I would do te filter myself if it would not void warantee and they
agreed to that and
noted it on paperwork. .
It is about S5 on 10 meters with beam (KT34 at 42 feet above and 15 feet
east) pointed worst case
and gets progressively less as I go down oin freq - cannot even find it on
20M and
below in my ambient noise.
