Well, Clark has been busy updating the TK20 series website pages with the latest info, &amp; has now listed that the <span style="font-style: italic">Extended IR battle range</span> hardware modification to the TK20E boards should allow for a <span style="font-weight: bold">&gt;30M</span> range. That is great news if accurate. We will have to wait until someone receives a newer board to test the IR after shipping of the altered 2nd batch resumes. So you must have been right Dan (YHR), the reason for your delayed 2nd batch board arrival was due to Clark making some IR modifications. Which as you said, is a good thing in this instance.

In the ECN area he now has this update listed under the <span style="font-weight: bold">2nd batch</span> information &amp; shipping schedule:
<ul> -All 2nd batch are upgraded to TK20E version
- Under H/W Enhancement for extended IR battle range, Start to ship by 10/20/2012[/list] So from what I would gather with the new information listed, is that the entire 1st batch &amp; the early shipped 2nd batch boards, will all most likely have the short IR ranges, which is a bummer. However, anyone that was supposed to get a 2nd batch board, but didn't receive it, was probably delayed their shipment to allow for the H/W upgrade of the extended IR power driver. So when those boards finally begin shipping on the expected Oct 20th date, the 2nd batch boards people get should all have the extended IR range ... lucky dogs!
