[Elecraft] ATU and Bandpass Filter
A question about the K2. Taking it to the club for FD and I have a bandpass filter (CF-20) which says "Never use radio's internal tuner with filter." I have the internal ATU installed. Is there a way to bypass that? Or should I just use the "main antenna" jack (manual says never use if ATU installed) on the bottom left, instead of the two midway in the middle? __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] 6 meters open this morning; listening 50.095 (CW)
Yes the tuners are great, and my 160 mtr full wave loop makes a good 6mtr
antenna, especially on receive.
But something about 6 mtrs on a beam, magic.
Hf beams, yeah they do mostly what you expect. But something about the
short wave length, maybe.
Maybe 2 mtrs is that way too, I don't know.
But every 6 meter beam I have kicks butt.
My KX3 and a portable MFJ 6 meter 3ele beam works like a big gun station.

Yes, even my 160M center fed dipole {256 ft} with its balanced feed

Re: [Elecraft] K3 PREAMP2
Brian, Since the IF takeoff point in the K3 is before any filtering or processing, I would expect the band noise floor to rise with the preamp(s). If you are referring to the receiver noise level with the antenna disconnected, then you have a valid point and I have no suggestions to offer. 73, Don W3FPR On 6/22/2017 5:46 PM, brian wrote: I use an SDR based panadapter (ROCKY) on the subrx.

Re: [Elecraft] RTTY with K3
Tom, Many USB to serial adapters do not work at slower speeds, and the FSK input to the K3 is at a slow speed (the baud rate for RTTY is slow). The Edgeport USB to serial converters seem to work well at any speed (I have the 4 port converter). Note that there is an apparent difference between "converter" and "adapter". If you do not wish to purchase another adapter (converter), you might want to set the K3 up for AFSK-A and use your soundcard to both the K3 LINE IN and LINE OUT - just set the audio levels as you would for any other soundcard data mode - 4 bars solid on the K3 ALC meter with the 5th bar flashing. Once the audio levels are set, you should not have to touch them during operation. An external soundcard is best as long as it is not set to be the default soundcard in your computer - if it is, turn off any sounds from your Operating System. You do have a soundcard that you are using for the RTTY decode, use the same one. AFSK-A is as good as FSK-D, and may give even better IMD performance. 73, Don W3FPR On 6/22/2017 5:01 PM, Tom Fitzpatrick via Elecraft wrote: Trying to set up RTTY on the K3.

Re: [Elecraft] 6 meters open this morning; listening 50.095 (CW)
Well... I have an 80-10 End Fed on the top of the wood fence. My KAT3
easily tunes it to 6 meters with 1.1:1 SWR, however I've heard nothing
except NW Reno [~10 mi], which probably wasn't Es. Two reasons come to
mind:
1. The antenna is one-way on 6 meters
2. Es is very selective as to location and apparently it isn't
selecting Sparks NV.

That's telling me that six meters could be a valuable band during Field Day. Consider having at least a dipole antenna that can to put into service. If the E-clouds are active, participants could pick up quite a few points in a band that has lots of room. The "skip" moves around a lot, but FD QSOs are short, so it could be a very productive band.

Get what you are saying but I go by what my Dad taught me... RE: Tools "Son, Buy the best tool you can find for each job. Save up if you have to. If you can't afford to buy the tool once, you surely can't afford to buy it twice." I apply that rule to tools, equipment, cabling, et al because ALL of those things and more are merely "tools" for me to accomplish some task.

Re: [Elecraft] Roofing Filters
An alternative thought. INRAD makes a decent product and has been around for years. I've used their roofing filter in my FT-1000 and I think it was in my FT-897 also(?). If I were looking to refit an existing rig, any rig, with a roofing filter I'd give serious consideration to INRAD's offerings. Specifications are a consideration. I'm not sure how the two products compare in the lab. If both are very similar then I'd say thank you to INRAD for selling at the lower price. Don't get me wrong. I really enjoy my Elecraft. One of the best rigs I've ever owned and definitely the best when portable. But if I want to say thank you I'll send them a card. 73, Kev K4VD On Thu, Jun 22, 2017 at 11:09 AM, Raymond Sills wrote: > I don't have a K3, or K3S... but if I did, I'd order from Elecraft.

Re: [Elecraft] Question about K2
Aaron, It is likely that the PA transistors have failed. Pull the top cover off and measure the voltage at the BASE of either Q7 or Q8. During receive, it should be zero, and during transmit it should be in the range of 0.60 to 0.64 volts. If it is anything other than that, remove the PA transistors - get the K2PAKIT from Elecraft, it has matched transistors. Once you have the PA transistors removed, measure the voltage at the solder pad for the base of Q7 or Q8 during a TUNE - if it is not in the range of 0.60 to 0.64 volts, replace Q11 and Q13 before putting the PA transistors back in. If the voltages on Q7 and Q8 look good initially, then the problem is something other than the PA transistors. You will have to do Transmit Signal Tracing as shown in Appendix E of the K2 manual to determine the failing stage. You will need the RF Probe or a 'scope with a 10X probe to do the signal tracing. 73, Don W3FPR On 6/22/2017 11:37 AM, Aaron K5ATG wrote: I got a question about the Elecraft K2.
