I see the complete opposite at least in North America. The level of activity on average on HF is much less than it was 40 years ago. Back then 160 m. was wall to wall at night. 80 m. cw was jammed.
Wow, either I lived in the wrong part of the states or things are a lot quieter in the north. I lived in Oklahoma from 2007 until 2010 and mostly just operated 40m and a few bigger contests. I also w
There are also a large number of licensees who never operate on ham bands, don't think of themselves as hams, but have licenses because they have a boat that goes off shore. There are a great many wi
Sadly, Rob and Jim are right. The numbers are there, but the activity isn't. Case in point, tonight, 40 and 80 cw are ghost towns. 160m has stns piled on top of each other for the arrl top band conte
The same thing has crossed my mind Jack. Or given the stampede to SDR rigs, class D boxes, the latest XQP3000 rig blah blah, there won't be anyone left who can converse and understand all vacuum tub
Aside from keeping boat-anchors running, exactly why does that matter? 73, Jim K9YC _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.c
Excellent point, Jim! I have some old boat anchor gear that I keep running, but I don't think every ham needs to have that knowledge. If they want to fix tube gear, they'll gain that needed expertise
Fortunately, there are lots of different aspects to our hobby. Having been involved with it since 1963, I have a fondness towards boat anchor radios. But, I frequently cringe when I read posts to oth
EXCEPT . . . for latency and lack of affordable knobs. Last reviews I saw still had turnaround latency between TX and RX at 350 mS. If both ops are running SDR, and trying to run full QSK, that's 0.7

Yikes!!! 350 ms? For most contesters that would be serious dead-air time. <div><div>Later, Joe, K8MP Sent from AOL Mobile Mail EXCEPT . . . for latency and lack of affordable knobs. Last reviews I sa
Rick, the latency on the latest SDR offerings has come WAY down, especially on the Flex 6000 series. They ARE contest capable. I agree on the knobs. I applaud the Flex Maestro interface panel - I thi
Yes, it used to be much worse. It is now 350 mS unless there has been some VERY recent change. Barry, if you say it's better, please specify who measured it and approximately when. Otherwise I strong
Ha, I love a good tussle ;-) I measured it on an ANAN-100D about a year ago. I've seen numbers for the Flex 6K that are similar. Latency of about 100-150msec for cw receive and ssb receive and transm
Here are some numbers for the ANAN-100D: CW Receive Latency 512 buffers 58msec 1024 buffers 87msec 2048 buffers 133msec Latency was measured by recording the external keyer sidetone audio and measuri
Sorry Barry, latency measured on the Anan does not necessarily apply to the FLEX 6000. Less than a year ago it was 350mS on the 6xxx, as measured by Rob Sherwood. We've had this discussion before and
I will personally measure the latency of the Flex 6500 and get back to you. I'm not believing 350msec at this point. 73, Barry N1EU _______________________________________________ TenTec mailing list

Paul you're measuring specifically cw transmit latency, correct? You did a really professional job of it - nice work! 73, Barry N1EU _______________________________________________ TenTec mailing lis
Paul, when you release the PTT and the green line drops, how long does it take for the receiver to recover? 73 - Rick, DJ0IP (Nr. Frankfurt, Germany) the FLEX 6000. I made timing and latency measurem
I'm not sure that's the right question to ask because recovery doesn't necessarily happen in real time. The Flex T/R cw recovery is really a mind blower for an SDR. But does it necessarily mean you c
