Hint, LMR-400 does NOT have a Diamond pattern on it! The last two

photos show their "Heads" looking at me taking photos of them. The photos

are of my un-finished transfer box at the base of tower 4.

band and is P-25 capable. The radio is now working on the 2M Ham band. And

it works using P-25 great! I am very pleased with this mobile radio.

purchased the EF Johnson radios at the Melbourne Ham Fest this past October and I

am very impressed with the EF Johnson mobile & portable radios. If you want to get into

radios would be a good place to start. Who knows, you might find some at the

My newest Digital Radios arrived 9-Dec-13.


Kirisun S780 / FP460

400-470 MHz. Digital C4FM FDMA Radio

6.25 KHz. Digital

Kirisun website

My first impression of this FDMA dPMR radio:

I am very happy with the Kirisun S780 radio. It performs very well in WFM

mode. The Digital Mode audio is excellent! Programming is very straight forward.

I purchased two from 409shop.com in China. I paid less than $120.00 for each

radio. I also purchased the USB programming cable, although I really wanted the

serial cable as no drivers are required for serial. I did purchase a spare battery.

I will be ordering more of these radios. I will next inquire about a Kirisun

dPMR Mobile radio for the vehicle or desktop. These radios have the same features as DMR radios.

SMS (Short Message Service) and pre-defined messages that can be sent to

a targeted user, a group or all radios on the repeater. In DMR you can tell if

the recipient actually received your message. And the recipient will have

a message waiting on his radio. These radios will also allow if

programmed, Stun, Kill and Revive function.


I purchased two more Kirisun S780 dPMR radios in December from the

www.409shop.com with delivery time of 13 or 14 days.

CIDR is the short for Classless Inter-Domain Routing, an IP addressing scheme 

that replaces the older system based on classes A, B, and C. A single IP address 

can be used to designate many unique IP addresses with CIDR. A CIDR IP 

address looks like a normal IP address except that it ends with a slash followed 

by a number, called the IP network prefix. CIDR addresses reduce the size of 

routing tables and make more IP addresses available within organizations.
