It's your choice whether or not to use amateur radio, and there's no requirement for it in chasing. Many successful chasers don't. However, without a radio or scanner to monitor 2 meter frequencies, you may not be aware of the integrated spotter network all around you, as was the case yesterday on the storm near Randlett.
There were a half dozen spotters on that storm in constant communication with the NWS and it was all live on the radio. Central Oklahoma has a linked repeater system where you can listen (or make reports) as Net Controllers for various counties report to the NWS in Norman the information relayed from their individual operators. Yesterday was a perfect example of why OUN's spotter net is second to none. Within ninety seconds of the tornado, four reports came in confirming the tornado, debris cloud, and precise location. One spotter (who I was very jealous of) was within 1/4 mile of the tornado for much of its lifespan and remained even after it was rainwrapped.
Chasers monitoring the Skywarn net would know (1) where the tornado was exactly; (2) that the NWS knew about it [Norman's net controller is on the air, too, relaying live radar updates to the spotters] and (3) what's going on in the rest of the OUN CWA, including the status of the El Reno tornado and the storm near Lawton. All of this in a very smooth easy-to-follow format that plays like a rehearsed production. These guys are very good.
I chased for 13 years without a HAM but i always had a scanner. Its a good idea to go to the net and get all of the areas spotter frequency and program them into your scanner. At least then you know or have a better idea of whats going on in the airways. Even with my ham I still use the scanner to scan frequencies while I monitor on HAM.
I saw some video of the Rndlett Oklahoma tornado earlier. It wasnt massive but it wasnt small either. About the same size as the first El Reno tornado. It did not do any major damage and only left a damage path through some trees near the Randlett cemetery.
If you don't want to spend the cash on a ham radio, most scanners will pick up the 2 meter frequencies. In Oklahoma, it's worth the investment to have this information available.
This is why I also think it's important for chasers to make themselves familiar with the integrated warning system by attending Skywarn sessions or listening to the nets to see how they work. We may not always participate, but if you'd have heard the linked repeaters yesterday, it might have been more understandable why OUN wasn't answering the phone.
