Default Icom 1020 mic

Trying to find a Mic for a old 1020 mobile. They seem to be hard to find. Don't care if it's a aftermarket. What's the difference between a 1020 mic and the ones for other icom?

You can use a current mic on those, 20+ years later they are still the same pin out. Try a HM152 or HM148.

Oh ok. Good to know as the local radio shop said a current Mic would not work and icom listed a different Mic. Iv got 2 other icom so I'll try their Mic. Radio may be a bust anyway as I need to program another Chan. But some quick reading it looks like a usb cable will not work

The original HM-100 mics were pretty weak. I had a few crack and a number of them develop bad PTT switches. The "heavy duty" mics are a much better choice.

Default F1020 MIC


The f1020 Mic EM-99 functions as a scan control. When the Mic is hung on the hook it is grounded. The 1020 can scan while Mic is on hook by pressing and hold a channel up or down button a second. The scan stops when the Mic is taken off hook.
Programming cables and software can be found eBay & elseware. Older PC use 9 pin serial. Newer PC can use USB provided the driver is installed correctly. Also there is a .PDF guide titled "Field Programming The F1020"

Example. To set squelch..

Press both up and down channel buttons at the same time while turning the radio on.
The PO button cycles through sections.
Cycle to section 1.
Press and hold P2 to use the volume knob to set squelch.
Turn radio off then on to set.
