[R-390] R-390A help needed

[Karsten Simon]

Hi Jaques,
> Does the "inferior sensitivity" of your R-390A only occurs on specific bands, if so which ones ?
Cannot check because all crystals have been removed and are currently being tested for accuracy.

> Does this mean that you do not have the proper equipment and/or knowledge to perform it yourself ?
I do have the equipment and probably also necessary knowledge. I lack the experience though and I am 81 yrs old. Until now nobody on this list has offered to help so currently I expect me ending up doing the alignment myself.
