Re: Harris TNC antenna in Waris handhelds?

It won't work well and depending on how it's adapted might now work at all. The base of the Harris antenna has a series of matching components to try to keep it relatively low (well usable) SWR in the Vhf low areas. They need a ground reference. That adapter posted is for a GP type of radio with the...

Re: DMR feature in APX

I heard from a birdy that they are planning on implementing this, but the radio will only support DMR or P25, and to change modes you will need to reboot it. So no DMR/P25 existing side by side. This definitely smells like some BS Motorola would pull Ah, like Kenwood's approach in the NX-3000 serie...
