[Elecraft] PCB Cleaning

Is it necessary to clean the K2 circuit boards, say with alcohol, before soldering? Harold Howells hhowe...@intrq.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:

[Elecraft] PCB Cleaning - followup

I may have answered my own question by going back through the first part of the manual. It emphatically says to not use any solvents at risk of voiding the warranty, I have read before though that cold solder joints can result from dirty circuit boards. Any thoughts? Thanks. HH Harold

Re: [Elecraft] K3/100 TX problem on 20m

Hi Paul, Could you please post the TX gain parameters recorded by the K3 Utility at the 50 watt level for all bands? If there is a significant difference in those gain parameter values between adjacent bands (say 30 and 17 meters) and the value on the 20 meter band, that may be an additional

Hi folks, I'm thinking about the KXPD3_KX3 for my KX3 radio for fair price please. Best from EU due to high import fee from outside EU. Thanks for offers if any... 73 - Petr, OK1RP http://ok1rp.blogspot.com K3 #0778 | K2 # 4800 | K1 #1031 | KX3 # 0602

[Elecraft] AX1 40 meter coil with KH1

I was wondering if the 40 meter coil from the AX1 could be used with the KH1. Don’t know if it would connect to the KH1. But now with the new right angle connector (not yet released), it would seen more likely to be a possibility. Or not? Bill W8BC

Re: [Elecraft] K3/100 TX problem on 20m

Do the TX gain parameter numbers have meaning such as dB or are they just relative numbers ? 73, Hal W7YNC > On 03/05/2024 6:35 AM PST Michael Carter via Elecraft > wrote: > > > Hi Paul, > > Could you please post the TX gain parameters > recorded by the K3 Utility at the 50 watt level >

Re: [Elecraft] K3/100 TX problem on 20m

Hi Hal, The numbers themselves have meaning to the DACs inside the K3, but in terms of actual units I don't know. The key thing is that as those values are increased, the drive levels from the TX DACs are increased, though I don't know if the relationship is a linear one. The gains of the LPA

[Elecraft] K3/100 TX problem on 20m

My K3/100 gives a high DC current warning when transmitting on 20m with power settings above 75 watts. Maximum output is about 80 watts and is unstable. All other bands perform normally with full 100w output and normal current draw. (50 ohm dummy load) I have done the TX gain and wattmeter

Re: [Elecraft] PCB Cleaning - followup

Hi Harold, It's certainly true that cold solder joints can arise from dirty/corroded PCB solder lands. The Elecraft boards in my K2/10 (now 17 years old, built by me) are very good quality with plated-through holes and durable solder mask. I had occasion to open my K2 to install the SSB and

[Elecraft] Happy Birthday to the K2!

Hi All K2 transceiver fans Built in July, 1999  is my K2/at transceiver # 136 operational on CW & SSB @ 10 watts I also have a gray shirt from Elecraft, with K2 # 136 by K1ND embroidered on it IT complements my K4/at  # 0200 very well Cheers to all the K2 "builders" from Jan, K1ND --

Re: [Elecraft] PCB Cleaning - followup

Cold solder joints might be caused by a dirty solder PC board BEFORE the soldering was done, but I can't think of a single reason why a good solder joint would turn into a cold one from crud on the board.  I would be curious where you read that myth. Dave   AB7E On 3/5/2024 3:33 AM,

[Elecraft] KH1 -

The KH1 seems to fulfil my need of a 40 to 15M CW QRP rig with SSB and AM reception capability. I'm currently studying the manuals issued by Elecraft and have a first question: did an OM or YL use the KH1 Programmer's Reference to precisely set the KH1 to his needs, using for exemple a Putty
