Then what i would do if i were you is ask that your bosses listen to you and give you feedback via email or something. I'm going to go out on a limb and assume that you guys are equipped with logger or profiler or something? That should be easy enough to do.
Why you should only care about what people in your station think:
1. Nuances are a big deal. every pd has their own set of nuances that they want, and it is your job to follow them. Bonus: it makes them happy
2. Format specific formatics. I have never worked active rock. I do not know what it demands. Someone like me could help with the basics, but I could never give you a really meaningful aircheck. I have never liked active rock, i do not listen to active rock, i have no idea what an active rock station is supposed to sound like.
3. In this biz, you will hear everywhere you go that consistency is key. There is a greater vision for how your boss wants the station to sound, and you are a part of it, otherwise you wouldnt be there.
4. You want to make sure that the person giving you advice really knows what they are talking about.
5. Youre in a place where you can be sure that your bosses are absolutely the best at what they do. probibly in the world. If not, in the top 5 or 10.
If youre that worried about it, i would suggest this: Take a second on air gig at a station in new hampshire. There is a lot of great talent up by you as well. If you want to make radio a career, it is definitely a great place to make a start at it. A great place for a lifetime career as well. the best way to learn anything is to do it as much as possible. I think just being on the air as much as possible is where you have the greatest chance to improve. You really wont learn that much being on-air one day a week. That, really, is the secret to losing that "green" sound.
