Re: L75 Amp Main Power Switch Availability
Just an update.... finished upgrading my L75.
Used the L75 for the first time the last night.
As reported by an old Heathkit HM-102 meter, I was able to obtain 500 watts output with 50 watts input on CW on 40 meters to a Heathkit Cantenna Dummy Load.?
Compared that read out against a Collins 312B-5 console and there it shows 600 watts. But the Relative Output function of the L75 shows way less.
Tried to adjust the Relative Output with the pot on the back of the L75, reaching the end of adjustment, but was only able to reach 300 watts. So something is still wrong there.
?
Apart from that, was able to use the amp to make a few contacts on SSB, CW without problems.
I kept an eye on the meter and adjusted accordingly to the manual (dip the plate and loading) thus not exceeding the plate nor grid mA stated there.
?
Also made a lot of contacts on 40 and 20 meters FT8 not exceeding 200 mA on the plate of the L75 (20 watts on the exciter) and performed very well. Got new countries into my log. I know this amp is not designed for digital 80% duty cycle modes but can be used with great care with very low input limiting thus the output.
?
Tested other bands and did well too. Only bands that I heard small arching was on 160 and 80 against a dummy load. Don't have an antenna for those two bands any way. From 40 and up was OK no arching.
?
So that concludes my report. Have to check on the Relative Output circuitry to find out why is not reading well.
i did adjust the meter for Plate and Grid according to the manual with a 1.5 VDC battery...

Re: Status of the Heathkit shop
Mike, I'm glad you caught it in time. I had a similar thing happen in 2007 and it scared the crap out of me. Two stents and apparently, they're still doing the job. Most of the pills will likely stay with you but doses will be changed and some will go away.
It takes a while. We look forward to when you return.

Mike,
Much rather you take care of yourself and never open up the shop
again rather than compromise your health by opening up too soon
due to any internal/external pressure.? We'll all be here when you
get back, unless one of us isn't as good of a bullet dodger as you

Hi Peter,
Ok, I just have to comment...
I was going to when you said you were?
going to build my cheap FS-4.. ?I might be
able to actually push you over the edge..
The Drake¡¯s were very stable by 1964
standards but today, they are really drift
monsters....
What i am running here is an advanced?
version I call my FS-5 with advanced?
stability.
If you build Bernie and my FS-4B hardware (with
digital dial) you could have a Drake that is
comparable to most new rigs in stability.
Simple theory is, measure the PTO
?frequency and if it drifts, you offset the?
band oscillator (Si5351 crystal based
synthesizer) by the opposite amount to
cancel the PTO drift. ?I am doing this now
and it is terrific, turn the Drake on cold,
tune in the net, then listen all day without?
changing the PTO, it is crystal locked!
I also have a mode I call channel lock...
Most operation nowadays is on even KHz
frequencies, so I only lock to the KHz.
Instant exactly ¡°on frequency¡±, no
?complaints from the new guys?
Real easy tuning, my Kenwood can¡¯t even do
this!
Parts cost can be as low as $11, I think.
Plus, you have all bands with NO old drifted
crystals needed.
My FS-5 design is still being developed but if anyone
wants something like the above,
maybe I can get Bernie to help me release?
it.

Gary

Rick:
I am not currently on the air with my TC-2/6 but I
have in the past used them.
While not too bad for casual VHF operating on CW/SSB,
they are not stable enough as is for any of the
digital modes.? I was getting drift complaints on
occasion from the SSB guys at times.? My answer...."do
you have big knob on the front of your radio for
tuning?"? OK - not really....but I did think that!?
Indeed some of that drift could be from the R-4/T-4
that was running the xverters at the time.? Need to
check that out further one day.
The receivers are not all that hot and would benefit
from a good low noise preamp ahead of them.? I did
some simple comparison testing a few years ago against
my SSB Electronics xverters and they were not as
sensitive, though I did not go as far as quantifying
that difference.?
I like to operate them just for fun, because I can.? I
just wish I lived in an area that some VHF DX was
possible...this after almost 40 years of VHF/UHF
DX'ing when I Iived in EN86 and FN02.? I am almost
surrounded by mountains where I am now in DN09, though
I do have a good shot at the moon most of the time and
am planning to get back into EME again. I won't be
using the Drakes!
I also have a P & H 6-150 100 watt 6 meter
transmitting converter that is fun to play with too.?
Brings back memories from using one of these in our 6m
station at VE3ONT during the VHF contests in the
mid-70's.

Re: Status of the Heathkit shop
I had angioplasty a few years ago. Had four stents installed, they wanted to do five but one artery was too blocked. Was told it didn't matter. It made such an enormous difference its hard to express. I was having burning pains, fortunately I did not have a heart attack and there was no damage. I was put on a powerful blood thinner for a couple of years (Plavix) and take a statin. So far all is OK. The worst of the procedure is being bored for four hours. I was expecting to have open heart surgery and was very relieved it was not necessary. They told me it could be done again if needed. So, the procedure does work. If you are on a blood thinner it can be a bother. The stuff I took will produce awful looking bruises if you stick yourself with a pin but they heal up.
??? This surgery (it really isn't surgery because they don't cut you) is not painful and will fix something that not too long ago would have killed you.
?? Good luck and feel better. I have two of the AC-4 kits installed.

Re: Status of the Heathkit shop
Mike - Let's not have any re-runs of this "coronary artery occlusion" stuff. Please take care of yourself, ease back into things, and do what your physician tells you to do. We really would like to have you around a bit longer - say like at least another 20-25 years or so (assuming you are around my age of 72).?
Best,
