I use an elevated ground .  My antenna is on a tower above the roof  and beside the broadcast antenna are two other antennas that I use for the ground .  They don’t seem to be radiating but help with sound quality more than anything.  My broadcast antenna has a capacitance hat at the top and it is not directly connected to the antenna but con…[Read more]

They say the electronics cause so much interference it completely wipes it out and the engineers won’t spend the money and time to shield it as it will add to the cost of the car and no one cares enough. Only public backlash will get them to change it. Some other makes don’t leave it out.

I am not a consultant engineer in any way! But the tittle sounds nice.
The Procaster with the 104″ antenna leaves you 14″ for a ground lead, not 3″.
Interesting about what the agent said about the ground lead and the copper stake not making any difference except for lightning protection.
Just make sure that the Procaster is mounted on top of the…[Read more]

Hi Mark and DJ,

In the United States, thanks to NPR, they want below 87.9. In radio world, they have been talking about the FCC letting these Franklin FMs on 88.7. I’m not sure about 76.1 to 79.9. There are no radios to tune that low here yet.

It is impossible to find open spots to run a Part 15 FM in urban or city areas here. These Translators…[Read more]

You and I and everyone knows this will never happen. The New Zealand model allows for 1 watt ERP  unlicensed but you just have to be registered with your location and frequency and no protection if someone interferes with you. You can have any antenna and location as long as you don’t exceed 1 watt radiated power from the antenna. They have from…[Read more]

I created a thread with a few pictures like 7 months ago 2 times and neither was approved so I gave up on this forum.  When the forum switched over to this crappy WordPress forum there is a better WordPress forum only like 7 to 10 members stuck around.  Part15 broadcast nowdays is not worth if people are not listening to radio any more. If the l…[Read more]

The forums are dead I know. I have stated my ideas as to why but that is up for discussion.
I think it’s great you have an FCC agent as a consultant engineer! You can’t go wrong there.
Nice you are getting good range. The radio itself can be the source of the muddy sound if the band width is too narrow. Radios do this as narrowing the bandwidth…[Read more]

Rich,

I hope Mark sees this. There is no point to argue or debate about the laws of physics here.

My Consultant Engineer, who is now also a “FCC Field Enforcement Engineer” (under contract) says it’s now all politics in the United States. During the Trump Administration, look what Head Commissioner Ajit Pai did to the FM Band here. He made a…[Read more]

RE: Using a 130-ft horizontal wire as an antenna for “Part 15 AM” stations

A horizontal wire produces horizontally polarized radiation, which has very high loss relative to vertical polarization as it propagates along the surface of the Earth.  Also, it does not radiate equally well in all compass directions.

A vertical conductor (vertical…[Read more]

Hi Mark,

The manufacturer or person that is making the 100mw Spitfire Transmitter is making the Mosquito One Watt Transmitter. It’s built in the same box as the Spitfire.

The downfall of the Mosquito Transmitter is there is no way (atleast he didn’t tell me) to measure forward power or reflected VSWR power. I did email them some time back. He…[Read more]

Can’t argue there. Is the Netherlands and Switzerland allowing the 1 watt license free?
That’s the Spitfire or the Hurricane right? The one in the UK?

I just logged back in today, October 4th, 2022 and saw Tim’s message. While everyone (In my opinion) has a opinion on programming content, I think we shouldn’t just give up on this board or throw the towel in just yet.

One thing I saw is Netherlands and Switzerland are allowing LPAM. In fact there is a person in the UK that is making a 1 Watt AM…[Read more]
