Re: Manual Notch Width

HI,

Hmm. The notch (manual or auto) is primarily designed do knock out heterodynes (i.e a single frequency). There may be restrictions in their design that might preclude the rejection of a wider band of frequencies. The designers would have to chime in. Have you tried to simply turn down the HI CUT to combat the problem? I often cut it down right to 2.1kHz with good effect. In my case that causes my 1.8kHz filter to cut in, but I doubt if if is makes much difference.

After weathering the first SSB contest with my new (last October) K3s, I have 2 comments:  awesome filtering(!!) - was able to mostly kill strong stations unless they were 500cycles away and really loud and splattered, and 2 - I wish I could adjust the manual notch width!

On the notch, there are some instances where tweaking the width a tad wider could cut some interfering nearby stations enough to make the target station legible.  Then there are occasions when the manual notch is too wide when an offending tone is right up against the target and the notch cuts into the target station (auto is way too wide).  My old IC-7600 and 7700 had that feature and could really help out on a crowded piece of band.

Any chance the adjustable notch width might be in a new software release?

I found my problem which was operator stupidity! Still trying to decide whether to part with my KPA500/KAT500 combo for a ne 1500.

Rick, I'm using the KPA1500 very successfully with an IC-7610. Plays very well together. Make sure the CI-V baud rates match or the KPA1500 won't track your 7610.

For setup details, see https://ftp.elecraft.com/KPA1500/Mod%20Notes%20Alerts/KPA1500%20to%20Icom%20IC-7610%20rev%202-4.pdf

Re: KPA1500 with non-Elecraft exciters

harry latterman <harrylatterman@...>
 

Can't say about using a 1500, but will say in my case I switch between my K3 and IC-7300 and have no issues. I have hooked to the KAT500 a G5RV at about 20 ft and a 7 band OCF at about 30 ft. The OCF will tune all bands from 80-6 meters with a 1.1 to 1 or on 60m, 30m  and 15m as high as 1.5 to 1. The G5RV will tune 160-10 meters with about the same... Note the G5RV is a 102ft one and should only tune 40-10 meters.

I always put the AMP in bypass and set the power to 20-30 watts for tuning, then adjust drive power as needed for what I want, generally 300-500 watts with no faults. Hope this info helps

Things go into default before the tuner reaches a good match. I'm either doing something wrong or there is an issue between the icom and elecraft combo. 

I'm interested in hearing from hams that are using the new 1500 with non-Elecraft radios and if they have any similar problems.

Drew:

I don't understand your question. The amplifier is a 53-volt amp. The IMD with PureSignal is below 53 dB.

Re: Sub RX Failure or some config change I haven't figured out yet?

John K3TN
 

Thanks for the all the ideas, no configuration changes made a difference so I filed a trouble ticket with Elecraft. Rob had me look at those configurations and then send  him the current config file for the K3. That config file runs fine on a reference K3 at Elecraft, so the conclusion is some kind of hardware failure.

Rather than pay to ship back and forth and Elecraft's hourly repair fee, Rick N1RM locally here (Reston VA area) has retired and is doing Acom Amp and Ke repairs, so will enlist his services to work with data and suggestions from Elecraft to locate failure.

I hate to say it but this K3S (about 3 years old) now joins almost every other piece of gear I've bought from Elecraft in having some type of hardware failure requiring repair - 3 different K3s, a KPA500, a KAT500 and a K3/Mini. The KPOD and a P# I bought used are the only exceptions. I don't think I'm hard on equipment but there I am one of only two common denominators!

K2 Fixed Audio Out/Amp Keying

Ed Pflueger
 

For those who are wanting the boards for the K2 that provides for a constant audio level for Data use and a way to key an external amplifier, FAR circuits has both boards for $4.00 each.  I sent the information to Don and he said that it was current.  I told Fred Reimers KF9GX (www.farcircuits.net )that it was hard to find the boards on his web page and he said an email or phone call would work to see what he had to offer.  It works because that is how I found out.

An ideal amplifier for the KX2 (and KX3)

CR
 

I've just finished building up a superb amplifier kit from Victor and Yana at eb104.ru that uses phase-change cooling. It will output 750 clean SSB watts with 4.5 watts of drive once I replaced the 10-dB attenuator pad with a 4-dB pi pad, namely a shunt 220, a series 24, and a shunt 220. The attenuator is easily accessible without any disassembly. (Arithmetic would suggest that the unmodified amp could be driven to near full coutput by the KX3.)  It employs one BLF188 as the active device with well designed protection from excessive drive, SWR, or drain current.

The amplifier is elegantly constructed, complete, and tested. You need only install it and its connectors into the included enclosure. As I should have expected from phase-change heat transfer, it runs cooler than any amplifier I have ever operated. See details at


I have built many amplifiers using eb104.ru modules. Their boards are of the highest quality in design and performance.

You will have to supply 13.8 VDC, 50--53 VDC at maybe 35 amps, and an external bandswitch box with a wafer switch, since the amp is designed to be bandswitched by a transceiver via the DB25 on the rear panel.  To play it safe I would use a PNP PTT  circuit to protect the KX2's key out circuit from the current drawn by the (three) bandpass filter relays in the amp.

K3 value?

with antenna tuner, wanting to sell his radio. No upgrades hardly used. What would be fair asking price? Serial number 4000 +

Transmitting 5 watts on my K3

Kevin Wagner <w2fa.kgw@...>
 

I've noticed when I have my power set to below 5 watts and hit the XMIT button the transmitted signal only happens for 3 seconds. If I raise the power above 5 watts the transmitted signal is constant. Is this normal and why does it happen below 5 watts?

I rember something to that.  I believe it has to do with the connection reversed and to change it need to press one or two while in the speaker menu.
