Saber VHF AM mod ?

Post by hycheng »

Hi there,
I know some ICOM FM HT's (IC-T7H) can be mod to Tx AM. I am just curious to know if any /\/\ot HT's can be mod to do AM ? In particular Sabers in VHF.
Thanks in advanced.

Thats a damn good Question.
Here's another:
What Motorolat Does work on VHF Air Band?

Or do you just have to stick with Icom for that

One of my yeasu mobiles will do VHF AM in the air band. It just takes a lot of button pushing to get it to work.

I thought standard made an air band portable as well?

What Yaesu unit is it that TX's on AM air?

I have the new VX-7R but it doesn't do it. Only FM.

Hi All..

Those ham radios cited above only have RX in AM, even you can transmit in the AIR Band, these radios transmit in FM. They don´t have AM TX circuits...

If you want to TX in AM, buy a Airband radio. I have one ICA22 and I can say you that the performance it´s ten times superior that those Yaesu radios.

When I don´t receive any signal in my VX1R (in AM mode) my ICA22 receives a clear and crisp signal of the tower and air traffic control

Regards,

AM with FM Modulation

Post by Caffiene »

I read that you could use an FM radio to "simulate" AM by tuning the FM radio 5 KHz lower or 5 KHz higher than the AM station. As the deviation of the FM radio passes into the receive passband of the AM radio, it is seen as an "amplitiude" modulated signal.
I've been meaning to try this with an AM radio and service monitor, but never had time to do it.

Has anyone else done this?
