When I read the initial post, I felt that it was totally baseless in its accusations. As I expected, the current edition refutes everything that the OP has stated.
The June 2020 edition contains:
1. An in-depth look at a QR layout (HOn3.5)
2. A brief look at a O scale layout in development.
3. SIX "how to" articles. All of these articles are very well detailed.
4. Measurements.... ALL in metric, except where it is appropriate to use imperial measurements, such as a prototype from that era.
So I randomly pulled another AMRM off my shelf to see how it compared, AMRM April 2019.
1. An in-depth look at a SAR layout.
2. FIVE "how to" articles, all of which were highly detailed.
3. Measurements. ALL in metric, except where it is appropriate to use imperial measurements, such as a prototype from that era.
4. I might add, two South Australian articles, plus two "how to" that were universal in nature.
Should I grab another to increase the statistical significance???? I don't think I'll bother....
So as to the "Beginner, intermediate and advanced" modeller. This is total nonsense. What is "beginner" to me, may be "Advanced" to you and vice versa. A modellers skill set is not linear. All of us have aspects that are better in one technique than another. Whether someone can do something is more related to how good instructions are and what experience they have. Have a look in the current "how to", ANYONE could do them. It is stated other Magazines have "beginner/intermediate/advanced" sections. I have only ever regularly subscribed to AMRM and Model Railroader (MR). I have never seen anything in MR in that format. Appreciate if anyone out there would identify the magazines that do adopt this format. I am sceptical that they exist.
As for publishing reviews, generally they are done independently of the AMRM. Therefore, if something has not been reviewed, then that means someone like you haven't written the review!
The claim that AMRM is NSW centric is kinda fair enough as on a population basis, that are where most of the modellers are. BUT my prototype (South Australian) is having a fair run. This edition, and the previous edition, have significant SA articles.
I have submitted and have had published, five articles. All with a SA flavour. As has been pointed out if you want something published, WRITE IT! AMRM supplies their guidelines for article submission. It is a simple "follow the process" procedure.
Lastly! Congratulations to James McInerney on publishing an excellent magazine. I wish the new Editor, Scott Fitzgerald all the best with his new role. To the AMRM, good luck with finding a new General Manager.
