I have for sale a 125cm dvap in perfect working condition. I used it with my D74 on 220 MHz. I could get a block radius around my house with the Dongle plugged in my kitchen. This will plug into your computer and be up and running in no time. I also have a pi 3 all set up with an image that works great. I was listening just before I took the pictures. THE PI IS AVAILABLE SEPARATELY and not included in this sale. Let me know if you want both. I am asking $150 for the DVAP with antenna and short cable.
