It's worth the rip to the tool store with a screw in your pocket to get a new driver with a large enough tip to fit snuggly. There is such a wide variety of screwdrivers available, that even the size number printed on the driver is not a good indication. I've had many a #1 driver with too sharp a tip to get a tight fit, the result is slippage and a damaged screw head and loose screw. The screw drivers with the sharp tip are Reid Prince screw drivers. When you buy a screw driver be sure you are getting a Philips screw driver. The Philips screw drivers can be recognized by the blunt or squared off tip. The K3 flatheads are very shallow because of the type of head and they will slip easily with a #0 or 'sharp' #1.

Hi all, If its magnetic, will the washer remain on the screw whilst on the head of the screwdriver? If so can do job in one go - hopefully. Regards 73 Alan Dave said: You probably would be wise to use a screwdriver that is magnetic so that you can move the screw down over the hole and begin to screw it in. The required washer can be places over the hole by just sliding them into position using the small slots on the side where the screwholes are located. But those slots aren't big enough to do the same with the screw itself. But using a magnetic tipped screwdriver also can cause a small problem as you approach the screwhole where you have already placed the washer. The washer wants to move due to the magnetic attraction. So you have to aim and shoot somewhat deftly. But it works. Somebody else probably has a much simpler solution to this. __ Sent from Yahoo!

Can do the job easily in one go using a 'Grabber' held in one hand, about as difficult as holding a pen and WITHOUT the risk of losing a washer, screw or whatever. The tool was also stocked by RS (Radio Spares) at one time, their stock number 537-293 and described as a Retrieving Tool.

After weeks of rain and wind the sun finally appeared in the mountains of Snowdonia today - and so did K3 000145, courtesy of UPS Express...! Original order placed on May 2nd, emailed invoice (47492) received from Aptos on December 3rd, UPS Shipping Notification received December 6th and the box delivered on the scheduled date (today). UPS Express without a hitch. No import duty demands (didn't expect any..) just a request for a cheque for 210 ukp for VAT and 'brokerage charges' which took about 3 minutes; like a visit to the dentist you want this sort of thing over and done with as quickly and efficiently as possible. Now to finish unpacking though it may be interrupted when I sneak off to take advantage of the superb afternoon conditions on 20m to the mountain/desert states of the western US we've been having the last week or so.

For the few hours that I was on throughout the weekend, I managed 10 CW

The good news is that I had done a little work on my K2 (QRP version--no

I know that's music to my ears!

Re: [Elecraft] [K3] Boot Camp / Windows XP experiences
Hi Toby, I don’t have my K3 “yet” but I am currently running an Icom ic-7000 with HRD under both boot camp (physical XP partion) and VMware Fusion (virtual XP) on my Macbook Pro. Both configurations work well but very dependent on the USB – Serial Converter cable used. I also run MacloggerDX under Leopard to control the Icom. I’ve found that some FTDI chip based serial converter work and some don’t. I’ve had the best luck with Prolific chip based converters but you have to go to their website to get the Mac driver. I think it has something to do with which drivers are most compatible with OS X. I’m not sure what chip the USB converter from Elecraft is based on but I’m pretty sure it would work fine. Also if you run RTTY with FSK only specific converters are compatible. I run N1MM with MMTTY under Fusion (virtual XP) on my Macbook Pro with my Prolific converter cable. It takes care of PTT and FSK. I’m sure the USB – Serial converter compatibility issue would apply no matter which brand of radio is being used. Good luck and enjoy your K3 as I patiently wait for mine.

RE: [Elecraft] K2 suddenly stops RX while on 160
Hi Don! Thank you for good advice once again! C75 in your K2 needs less capacitance. You can try several other 470 pf capacitors (NPO disc ceramics or C0G mono capacitors) to see if you can discover one that is on the low side of tolerance rather than the high side (like yours), or you can replace C75 with a 390 to 450 pf capacitor and add padder capacitors to bring the total capacitance up so the 160 meter VCO voltages are in the 1.5 to 7.0 volt range over the entire tuning range. Today I got some NPO disc ceramic caps and tried different variations. With 330+150 pF in parallel measured VCO voltages are now inside 1.5-7.0 V: 1800 kHz 1.6 V 2000 kHz 4.0 V These new capacitors are not small in physical size, bigger is 10 mm, about 0.4 in diameter.

Re: [Elecraft] OT: more than you should ever want to know about Screwhead Types
Yes, it is true that there are many screwhead types. Contrary to comments earlier on this reflector, using a Pozidrive as a Phillips screwdriver is not always a good idea - the Pozidrive will not fit into a correctly sized Phillips screwhead forcing one to use a smaller size Pozidrive. One thing for certain, those Phillips screwdrivers that have a sharp tip are not Phillips type at all - either blunt the point with a grinder until it fits with precision into a Phillips screwhead or buy a proper Phillips screwdriver.

Another piece of trivia. Robertson (named for the innovator) screws are a Canadian invention, like the Blackberry, Zamboni and other time saving devices.

Re: [Elecraft] Recommended K3/100 filters
FWIW I hear the difference as the 250Hz kicks in as I change the bandwidth from 300Hz down to 250Hz, the difference is (I think) less DSP noise - maybe Lyle can explain. It's not a problem at all. For SSB I have the 1.8kHz and that really is a great filter, I was listening on 40m a few hours ago with 1.6kHz bandwidth - very, very good. I agree about 1kHz for tuning about on CW.

[Elecraft] Recommended K3/100 filters
Terry It's just the usual removal of adjacent signals, no big click or anything like that, just a smooth transition with an improvement in skirt selectivity - much as you would expect with a narrower filter. Under low signal level band conditions as here at 2230 local time on 80m, there's not much difference, under contest conditions when 40m is pounding in it's more noticeable. It's hard to describe, the K3 just does what you would expect a decent receiver to do without fuss, filter ringing or any other artefacts. I guess the only real test is to have two K3s side by side, one with filter A and the other with filter B as the DSP bandwidth is linked to the roofing filter, so it's hard to open one IF leaving the other narrow. Suffice to say I think the $120 for the 400 Hz 8 pole CW filter is money well spent, as to whether it's necessary to use 8 poles rather than 5 is something I can't answer, as I only have 8 pole filters. 73 Dave, G4AON K3/100 #80 === Dave, Perhaps you can comment on what sort of improvement was noted when the 400 Hz filter was switched in.

[Elecraft] K3 Filter Switching Problem?
Warning! K3 filter use item follows. Currently, I only have the standard 2.7 KHz filter in the FL3 slot on the RF board. I chose this location due to potential future additions of the 2.1 and 1.8 KHz filters, in slots FL2 and FL1 respectively. Here is what I observe: With FL3 manually selected via the XFIL button; when I try to rotate the Width control below a value of 2.7 KHz, the rig automatically switches to the FL1 position, which is empty. The receiver goes dead. When I quickly reverse the Width adjustment, FL3 is not switched back. I have to manually select FL3 again with the XFIL button. Once back in FL3, I can adjust the Width control to higher values above 2.7 KHz with no problem and the passband gets wider. Is this normal? I thought the DSP circuit would continue to narrow the passband even though the roofing filter is broader. But, why does it switch to an empty filter slot? Did I do something wrong during the Configuration setup? Is this a firmware issue? I have not downloaded the latest updates yet. If I had narrower filters in the FL1 and FL2 slots, then I would expect the circuit to auto-switch to those as I narrowed the passband via the Width control. And, they should switch back in reverse order as I widen the passband. Right? 73, Henry - K4TMC K3 #98 More new features than ever.

This is very misleading, because the ultimate selectivity is provided by the DSP. So even though there would a big difference if the selectivity were provided only by the filters, they are only needed to protect the DSP. A signal *within the crystal passband* has to be S9 +30 dB before it will activate the hardware AGC; so if a signal is already on the skirt of the crystal filter, it will have to be even louder before any desensing will take place. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

If you only have one filter installed and it's in FL3, that should be the only one set as FL3 ON = YES. FL1 ON, FL2 ON, FL4 ON and FL5 ON should all be set to NO for all modes. - 73, Greg - AB7R Whidbey Island WA NA-065 K3#0009 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Here's a tip for setting up the 500 Hz filter if you use one. The actual 6 dB bandwidth is 565 Hz, so in the FLx BW menu I set 0.60. This means the 500 Hz filter is activated at WIDTH = 600 instead of 500. The advantage of this is when you use DUAL PB. That function sets the narrow passband to 150 Hz and the wider passband to 600 Hz. Since the 500 Hz filter is now activated at 600, this means the 500 Hz is in use for DUAL PB, which can greatly help desense problems versus the stock 2.7k, which would otherwise be selected in DUAL PB mode. 73, Bill W4ZV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

...he advantage of this is when you use DUAL PB. That function sets the narrow passband to 150 Hz and the wider passband to 600 Hz. The wider passband is 600 Hz at its narrowest setting, YOU can make it much wider just by rotating the WIDTH control once you are in DUAL PB mode. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

KK7P wrote: The wider passband is 600 Hz at its narrowest setting, YOU can make it much wider just by rotating the WIDTH control once you are in DUAL PB mode. True. But as soon as you widen to 650 Hz, the next higher roofing filter kicks in and (in my somewhat limited experience of 8 days) there is a *HUGE* difference in desense susceptibility between the 500 Hz and higher BW filters. Living in the land of GIANT signals where I do on 160, DUAL PB would be virtually unusable without the 500 Hz filter. 73, Bill W4ZV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 Filter Switching Problem?
BTW: FL1 should be the highest bandwidth and FL5 the most narrow Other way around, but it actually doesn't matter. Any filter can be in any slot and the DSP will select the right one as you crank the bandwidth down. The reason for keeping them in some order is so that when you rotate through them with XFIL they'll make sense (i.e. they get narrower and narrower each time you press, then when you're at your narrowest the next press takes you to your widest).

270 x 2 = 540, so the difference is 356Hz. ;-) However, the 250 Hz filter is actually 370 Hz at the - 6dB points according to previous e-mail here. With the K3, the point of diminishing returns for IMD (and close in rejection) is perhaps - 30dB instead of -60dB or more in a conventional crystal filter only radio. If we use a straight line (linear slope) from the -6dB to -60dB points the 200 and 250 Hz filters look like this: 200 250 - - 6dB 224 Hz370 Hz -60dB 896 Hz777 Hz slope 6.22 Hz/dB3.77 Hz/dB (one side) -10dB 274 Hz400 Hz -20dB 398 Hz475 Hz -30dB 522 Hz550 Hz -40dB 647 Hz626 Hz -50dB 771 Hz702 Hz By this simple calculation (or by plotting on graph paper) one can see that the 200 Hz filter should do a BETTER job as the most narrow filter. It remains tighter to about -35 dB and the five pole design should result in less pulse stretching (ringing in the presence of static) than the 250 (really 350 Hz) filter. 73, ...
