Title: Barker & Williamson 374 Dummy/Wattmeter Question Post by: Ed WA4NJY on May 04, 2010, 08:13:49 PM I am too cheap to buy a manual. Just need to know upper frequency limit for accuracy. thanks, Ed WA4NJY Title: Re: Barker & Williamson 374 Dummy/Wattmeter Question Post by: WBear2GCR on May 04, 2010, 10:21:15 PM check to see if it is on edebris.... click on BAMA above on the banner buttons, and hit the "mirror site", edebris... _-_-bear Title: Re: Barker & Williamson 374 Dummy/Wattmeter Question Post by: Ed WA4NJY on May 05, 2010, 07:20:20 AM Thanks for reply. I checked BAMA early on, not listed. Most Likely this is good for 30 mcs. I will try it on VHF this weekend against a known good meter. tnx, Ed Title: Re: Barker & Williamson 374 Dummy/Wattmeter Question Post by: WBear2GCR on May 05, 2010, 10:09:48 AM Got jpeg? Is this the one that mated with the T-368 by any chance? _-_-bear Title: Re: Barker & Williamson 374 Dummy/Wattmeter Question Post by: Jim, W5JO on May 05, 2010, 10:36:49 AM I have a B&W 334A and the manual says accuracy is 5% up to 30 meg then 10% up to 150 or so then 20% up to 230 or there abouts. I don't think there is any difference to speak about unless the 374 did not have the glass mounted SO 239. Also if the insulation between the center pin and shell is there it won't be listed as accurate. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
