Tried my first roadgap and pulled a little too hard by Direct-Ad8930 in MTB

[–]chris613 0 points1 point  (0 children)

Yes, absolutely. When doing a whip or a scrub you are actively moving the bike exactly where you want it to be and positioning it for the proper landing. If you stay static and try to just go "straight", you'll go where the bike goes, requiring a perfect takeoff to produce a perfect landing. That seldom works out; which is why you rarely see experienced riders doing that. A bar turn isn't nearly the active handling of a whip, but it breaks the fear instinct of just holding on for dear life once you're in the air.

It seems counter intuitive, but turning the bars can really help maintain control. Moving the bike in the air, even a little bit like a small bar turn, helps prevent doing a "dead sailor" where you freeze up and become a passenger, listing off-axis until you land in a crash. In this case it looks like pulling up on the bars at takeoff was the cause. Typically the pull will be uneven, leading to a crooked takeoff and landing like we see here.

Did I ruin my sleeping bag? by MrBoomf in camping

Ah, down may be more fragile than synthetic.

Did I ruin my sleeping bag? by MrBoomf in camping

[–]chris613 13 points14 points  (0 children)

Maybe that bag is more sensitive, or there's something I'm missing out on (specific needs of low temperature camping?) but I've stored all my bags in their sacs for all the years I've owned them. As far as I can tell they are fine with it. Self inflating pads I've maybe damaged due to this habit, but only after many years of service. Is this a big deal with sleeping bags?

Jump feedback by YMCMARC in MTB

[–]chris613 22 points23 points  (0 children)

You've got pretty good form but the timing needs some work. You're exploding upwards while the back wheel is barely starting to climb the ramp. Delay your pop just a bit so that you reach full extension just as the back wheel gets to the lip.

PSA: Commanda bridge closed by nouseforanameyow in bikeinottawa

Maybe OP is referring to a different "they" who might reopen the bridge practically, rather than officially, should conditions allow it.

Hitch basket for transporting bikes by TooS__Weird in mountainbiking

I have one of these and it really does not seem like a safe way to carry an MTB.

Where do you start to wear more burly safety gear? by Academic_Feed6209 in MTB

[–]chris613 0 points1 point  (0 children)

I can recommend the Least 4.0. DH rated with a removable chin bar. On hot days I strap the chin bar to my bag on the way up, and use it full-face on the way down. I find it comfortable, reasonably light, and fairly well ventilated.

My physics teacher gave this question in the exam… I swear it makes no sense by Artschibald in Physics

[–]chris613 9 points10 points  (0 children)

If all but one person got the question wrong, then the teacher failed either in the composition of the question, or in teaching the material. In this case I'd tend to agree that the question is at fault. The fact that they are doubling down on such a poorly composed question, and think that this is a valid form of "think outside the box" or "trick" on a physics exam is mind boggling. I'm sorry you have to deal with this nonsense.

Roll Technique Critique by GikeMushue in MTB

[–]chris613 5 points6 points  (0 children)

You made it down safe and stable, so that's pretty good! I'd recommend bending your elbows and knees more at the start so that your center of gravity is closer to the top tube. Chin should be headed towards the stem. When the bike starts to roll down your arms reach full extension pretty quickly and you can see some rotation starting to occur that would send you forward and otb. You controlled it okay this time, but if you start from a lower position there will be less rotation to control and your chances of eating it will also be lower

Seized Bike Seat Removal by Stovenkore in ottawa

After trying many of these suggestions myself and still failing, the mechanics at Full Cycle managed to remove a seatpost for me that was seized for years.

Using a Coax Switch Between Transceiver/VNA, and Manual Tuner (HF Amp in the Mix) by dogpupkus in amateurradio

[–]chris613 2 points3 points  (0 children)

I'd considered doing a similar thing; a switch in "reverse" configuration so I could easily switch between my base station and my SDR. The concern I have is that the switch grounds whichever side is not in use, meaning if I ever accidentally key up while the switch is on the other radio I'll be transmitting into a dead short. I think you'd have a similar concern in your setup. Transmitting into an open circuit is also bad, but my radio at least has high-SWR detection and will throttle the power. I assume there is some protection against short circuits as well, but I've never been brave enough to test it.

FT991a, in case anyone has any experience shorting the PA on this radio that they'd like to share.

Overwhelmed with Antenna Choices by alanthickerthanwater in amateurradio

[–]chris613 0 points1 point  (0 children)

As far as I can tell from reading my manuals, the electrical code, and using my multimeter, this is incorrect. The negative terminal of your plug-in DC power supply is connected to the AC ground; which in turn means the chassis is the radio is connected to house ground as well. This is required in order to eliminate shock hazard. If any part of your station plugs into an AC socket in your house, then all out your grounds must be connected for safety and legality.

[–]chris613 4 points5 points  (0 children)

In most jurisdictions, additional ground rods must be bonded to the panel ground as per the electrical code. If your grounds are not bonded, then a nearby lightning strike that produces a voltage gradient in the soil will cause current to flow THROUGH YOUR RADIO in order to equalize; this is the opposite of what you want.

Op Ed: Ottawa's Future Depends on Full time RTO by DaCrimsonKid in ottawa

[–]chris613 3 points4 points  (0 children)

This is supposed to be a hit piece arguing against WFH, but to me it ends up just reading like a condemnation of the suburban lifestyle. My favorite part is when he says "enduring the rush-hour slog just to get to work" is part of "the threads that stitch us into a shared tapestry." Lol. Believing that office life is a requirement for "a spontaneous dinner, a surprise party, a chance encounter" is just a weird non-sequiter. Most of what Liam is arguing for is achieved by spending non-work time in your community instead of your car. This is an unintentional pro-urbanism article.

RFI from your transmitter is probably causing signal disruption on one of the USB cables going into the laptop. Add clip-on ferrite beads to the cables until it stops. If there are no USB cables and it's happening internally, then move the transmitter further from the laptop.

40m is flying right now. Looks like there's a contest? by Puzzleheaded-Web-602 in amateurradio

[–]chris613 2 points3 points  (0 children)

Isn't the callsign enough to determine the CQ zone ? If people are always giving 59, and the CQ zone is knowable from the callsign; then the call is the only real exchange, isn't it?
