QRQ 30

I am currently reading Maj Plaster's newest book, and they talk about the radio that the 1-2 usually carried. Can you give us some stat's on it. And maybe even some of your TTP's that were used on patrol?

Thanks

All we carried on an RT was the PRC-25. Towards the end they had switched to the PRC-77. After I left in Dec 68 I believe they started using the secure voice equipment for the PRC-77. Each american also hat a URC-10 survival radio. The HFs carried squad radios (CRS nomenclature) for internal communications. When I went to Special Projects I also carried a GRC-106 for direcxt commo to higher.

When I first got into country the Vietnamese were still using the Prc-10. They got our 25's when we switched to the 77. For those who may not know, the difference between the PRC-25 and the PRC-77 was an extra connector for the secure voice. Internally it was secure voice capable.

What was the weight of the 25, and freq range? Also what kind of range did you get with that. You mentioned in another thread that the enemy had very good RDF capability....what were some of the techniques that you used to beat that.

Those were 35+ years ago. I could look up the range and weight but so can you. No insult intended.

There is only one effectice counter measure for RDF -- silence!! When I was at Khe Sahn Teams were alright until they broke radio silence. Then, more often than not they made contact within 30 minutes of breaking radio silence.

And then there were the wheels in the puzzle palace. It would have been sufficient to have no radio transmission unless contact were imminent. A SITREP could have consisted of a visual (mirror usually) OK and the COVEY knows your location. But the wheels just had to have a daily SITREP broadcast and it usually resulted in contact. They didn't believe that "No news is good news." Curiosity killed the cat but the cats were on the ground and the curious ones were in secure, air conditioned bunkers.

http://www.answers.com/topic/prc-77

as Terry mentioned earlier, the only real difference between the PRC 25 and the PRC 77 was the adapter for the KY 38 secure voice system (aka the Slave Rig to all RTOs who carried one...speaking as a former dope-on-a-rope...)

And in some far places the PRC-77 is also quite well known..
