Peter, thank you for the words of encouragement. After restoring other parts of this receiver and refinishing trim, etc, it was certainly a disappointment to have these issues with a realignment. I've done many broadcast radios in my collection of prewar sets and even an R 388 Collins so this one was a real surprise.   
I'm sure that there are other problems afoot here. Last night I checked the frequency counter against my FT2000 and they agreed to the last digit. Where it falls apart is when the level is reduced. The frequency counter becomes unreliable and I really suspect the signal generator changes frequency as I reduce the level to keep the AGC voltage within spec.   I connected the frequency meter to the signal generator at high level - a volt or so - and then reduced the level and it can vary considerably. Was it the meter or the generator at fault here? Well, I cross checked it with my scope.  A scope is too broad an instrument to make a good frequency determination but it did show the trace expanding or contracting slightly with level. Disconcerting. 
Now that I am able to produce a clean 60 KHZ with the signal generator, I'm able to get a good peak with the transformers in the 3rd IF. However, where they peak depends up what bandwidth is selected and which sideband is selected. There could, I suppose, be issues with the transformers themselves or as someone mentioned earlier, coupling capacitors. Some bandwidths produce a higher output than others, depending upon which bandwidth was selected when the alignment was performed. The peak at different points for different bandwidths. Hope this rambling makes sense.
Very Best, Jim

Looking for a really strong performing 80/160m wire antenna (commercially made)

The words "strong performing wire antenna" and "commercially made" don't belong in the same sentence when it comes to 160 unless you are talking about NVIS contacts.  In that case a low dipole will work.  At heights that most hams have available, it won't be a strong performer but it will get you on 160.  If you are interested in learning what it takes to get a good 160 antenna (both for transmitting and receiving) buy the ON4UN Low Band DXing Book.   There is a ton of stuff in that book applicable to other bands, but he concentrates mostly on 40, 80, and 160.   Money well spent in my opinion.

Jerry, K4SAV

Grundig G6 Buzz Aldrin model.  About $50 at Rat Shack.
I doubt I can find this in Europe.

Maybe buy online?  Amazon or Radio Shack
Shipping + VAT would not make it worthwhile.

It's a semantics game anyway.  What some people see as "choice", others see as "requirements". e.g.:  One guy sees it as a choice to live within 10 minutes of their work, other guy calls it a requirement. One guy sees it as a choice to live in a house less than 3 years old, the other guy requires the house be less than 3 years old. What they're missing is that those "requirements" involve making a choice.

And so on.  Word games.

The problem with the "requirements" approach is that the problem becomes over specified:

I wanna house between 3 and 5 years old.
AND every room has a walk-in closet measuring 20x15 feet.
AND there must be 4 full bathrooms.
AND the lawn must be in perfect condition.
AND 10 to 15 minutes commute to my work.
AND 10 to 15 minutes commute to my wife's work.
AND 10 to 15 minutes away from the grade school.
AND 10 to 15 minutes away from the high school.
AND the high school must be within the top 10% in the state.
AND the grade school must be within the top 10% in the state.
AND it must cost between $250,000 and $300,000.
AND the HOA fees must be less than $100 a month.
AND every home in the neighborhood must be painted only with approved colors.
AND nobody is allowed to wash their car on the street.
AND no kids are allowed to play basketball in their driveways.
AND nobody is allowed to have a shed more than 10x10 feet.
AND only certain kinds of flowers are allowed.
AND …
AND …
...
AND … I must be allowed to put up a 65 foot tower and tri-band beam.

Oh dang. There are no houses left within 200 miles that meet my requirements!  

Therefore the Federal Government must step in and override the HOA and gimmee everything I want regardless of any objections from any of the neighbors ...  because I'm a HAM HERO and am required by the Federal Government to be prepared to save the world some day


And another dishonest post. HR 4969 would mandate only REASONABLE accommodations and you know it. Stop flailing around yelling towers, towers...  ooohhhh  nnnooooooooo...

530 is still a nice rig. I have a mint 830 with external VFO 230 (Digital) that I have had in storage for a few years now. I have had them for for over 20 years and they were always a pleasure to use.

You qualify for the DXCC Challenge automatically when you have 1,000 current band countries verified by the DXCC desk. This is done at no cost to you.

Ordering the plaque is separate and costs extra. This is not unlike the 5BWAS, 5BDXCC, DXCC Honor Role and Top of Honor Role plaques.

These stories really serve to bring out the inner insurgent in some individuals. The upside is they post with traceable IPs and a registered callsign..

They don't need your call sign or even your IP! Everything you type is intercepted at your ISP and they have that cataloged by your account info and credit card info.
Any statements made thus far probably add into thousands of other such statements made by millions of internet users. IOW it's just QRN as far as they are concerned.


Your IP can tell far more than you think. Facebook is one of the biggest snoopers right under your nose yet many help them. Their main source of revenue is selling your surfing/web habits to others for marketing. The have several patents on how to snoop. One day they will loose favor and something will take its place too.
