As long as money is coming in the door from advertisers, nothing will change.

Technically, since radio stations are no longer required to have a a physical studio at the location of broadcasting, they can consolidate to a single national location and have everything programmed and linked out to the cities of broadcast and make all of these high powered stations kind of like translators. Actually, NPR has done that for years in various states, (Like here in WV.), and nationally K-Love is doing that now,   http://www.klove.com/    Take this to a commercial level and there you go. The idea of just a handful of people doing programming and sales to a few hundred stations nation-wide is a golden goose that would be just too hard to pass up. As it is, most of those people left can do their tasks from home. I can see commercial and non-profit conglomerates going to that model exclusively this decade.

This isn't too far from the rumors I'm hearing.  Why else did most of the layoffs happen in programming and on-air...

Plus, remote voice-tracking of air shifts has been going on for well over 20 years.  Some jock working from home can be on 6 stations coast to coast, and do it all before lunch.

Iheart goes through a restructuring about every decade.  I have a feeling larger changes are on the horizon,  all heresay at this point however.

Rumor on the street is about 1200 people are getting axed.

FWIW, wwv is using 5 slanted radials in their systems.

In my line of work, I'll worry more about the joint aches I get after spending 30 minutes at a high power am site..or the end fire off a full c fm...or that leaky switch at a tv site thank you.  I've heard of a lot of am broadcast engineers developing brain cancer in their later years.   Cellular is the least of my worries.

I use 8 on my portable antennas as anything more in the field does little to improve performance, only adds setup time and p.i.a. factor.  On a permanent setup, 16 is about the point of diminishing returns.  At 8 radials, shifts in ground conductivity due to seasonal and weather shifts will be much more noticeable.  On some models I've seen, the difference between 120 and 16 radials is a few db... not worth the trouble imho.

Interesting point about using a vertical. I tend to stray away from them as a lot of people say 'They radiate poorly in all directions' I have used verticals for QRP portable ops with a bit of success. I have thought about adding one for various operation anyway. Im always welcome to another antenna in yard! Yes. I need to utilize Grey line better in general. It's a simple method, that just involves being in the shack at the right time. Any favorite sites for Greyline mapping? Yes I have used some, just curious if there are opinions on this. Thank as always!

The folks claiming verticals suck are the same folks that use two radials on said antenna in a suburban lot with no view of the horizon, just the neighbors plasma tv, then wonder why the match sucks and is noisy as hell.  I've had quite my fill of ham 'experts'.

The right tool for the right job...verticals really shine in a low noise environment with a clear shot to the horizon.  They do not do well in a crowded suberbopolis.   In such situations a mini whip or a loop is a much better choice.

The RF Workbench / Re: Transmitter set up
« on: January 14, 2020, 0119 UTC »
There are many variables..

What mode?  AM or SSB?  AM requires more power for good reception but generally better audio quality.
What distance is your audience from you?  The farther away your audience, generally the higher the power.
What frequency?  Lower frequencies generally require more power to overcome higher local noise levels at low frequency.

This time of year NVIS can be had during the day on 4-6 MHz.  Assuming a location on the east coast and also targeting said such, 50-100W (200-400W PEP) AM should be sufficient.  SSB will require about 1/4 to 1/2 above values.

Everyone's definition of bare minimum is different.  I would recommend some sort of audio processor before the transmitter to both protect it, and prepare the audio for transmission.  If everything you will do is canned, this can be done in the computer after a final mix is made.

It is important also that the transmitter is well matched to the antenna.

No real 'trade secrets' in any of this stuff.  I have worked on and off in commercial radio engineering for almost two decades, and most of my airchain is modeled after what the commercial guys do.  This is after all a hobby.

All the more reason to approach this hobby with some level of professionalism.  If you don't give people a reason to complain or hold a grudge, all the better.

6950.0 KHz AM 1-4-2019 0201z  Threshold audio over local noise, Police 'Every Breathe You Take'
0204 more Police, 'Walking on the Moon'.  About S7 to S8 over an S7 noise floor.
0207 starting to get hammered by CODAR on USB.  Boards of Canada 'Music is Math' now.  Interesting song selections, all stuff I know :)
Signal took a dive into the noise about 25 minutes ago and never recovered.  Carrier off @ 0253z.

Thanks for the show!

I also noticed the 20 KHz option disappeared from most of the Kiwi's online....sad :(

Huh? / Red Ukrainian Borscht
« on: December 31, 2019, 1731 UTC »
I got the taste for this watching some of Bald & Bankrupts' video while bumbling through Belarus.

Ingredients;
1 16oz pkg pork sausage
3 medium beets, peeled and chopped
4 carrots, peeled and chopped
4 small potatoes, peeled and cubed
1 large yellow onion, chopped
1 6 oz can tomato paste
3/4 cup water
1/2 head of cabbage cored and chopped
1 8 oz can petite diced tomatoes
3 cloves of garlic, minced
olive oil
1tsp white sugar
salt & pepper
parseley
sour cream

In a skillet, add the pork and crumb.  Cook until done.  Drain grease and set aside.

In a large stockpot, bring 2 quarts of water to a boil.  Add pork, and once boiling again, add beets and cook until they have lost their color, about 10 minutes.  Add potatoes and carrots, cook until tender, approx. 15 minutes.
Add cabbage and can of diced tomatoes.

In a skillet, add oil and onion and cook until tender over medium heat.  Stir in tomato paste and water, and mix until well incorporated.  Add mixture to stockpot contents along with garlic.  Remove from heat, cover and allow to stand for 5 minutes.  Taste, season with salt, pepper, and sugar.

Ladle into bowl, garnish with some parsley and a dolop of sour cream.
