[Elecraft] SP3 intermittent A/B switch

My apologies if I've overlooked SP3 discussions including this annoying symptom on mine. I purchased this SP3 new a couple years ago. After a few weeks i noticed the A/B selector switch had become rather touchy, and at times the audio would not be present unless I jiggled the switch a few

Re: [Elecraft] K3/100 Voltage Drop when transmitting

yep, OHM's law lives, even after at least 61 years since i first studied it in preparation for my novice test. Furthermore, I'm grateful for the outpouring of ideas and suggestions received here on this forum. I think I have learned enough to convince myself that I have improved my situation as

Re: [Elecraft] K3/100 Voltage Drop when transmitting

Well, i have received many helpful replies both publicly here and in private emails. Thanks to all for those ideas brought forward. What I've gleaned to be most useful from your responses has been the suggestions to investigate the power cord with power poles connecting the K3 to my switching

[Elecraft] K3/100 Voltage Drop when transmitting

At first i suspected my Solar power system which was installed a year ago, but now I plugged my K3 S/N 7317 directly into my 25A switching DC power supply, and when key down, 100W in CW, on the internal K3 Power Meter i see a voltage drop from 13.6 to 12.0VDC. My power cord is a 6', 10ga

[Elecraft] Anyone use Solar Power for your ham shack?

I've employed a small solar power system to supply my ham shack which includes K3-100/P3, two PCs with flat screen monitors, and 20" flat screen TV. This began as a basic test bed to understand Solar Power, so i know i have lots to learn, and perhaps I have answers to help others with the same

Re: [Elecraft] P3 SVGA interference -

Somehow I managed to lose my last post describing the attached photo. suffice to say my Span is set for 14.000-14.104MHZ and my cursor is tuned to 14.029, but notice that the baseline noise level while near S-2 across most of the band, shows a hump back at the center of the screen and the

Re: [Elecraft] P3 SVGA interference -

I am almost overwhelmed by all the very thoughtful suggestions. Here's what I know so far. I had previously performed the idea of turning off all items in the room except for the radio and P3, but the reported symptom remains. I then switched my antenna switch to the grounded position, and the

Re: [Elecraft] P3 SVGA interference -

I have the P3 attached to a HP 23" flat screen. I power off the external monitor and still have the issue on the P3 internal monitor. I power off the monitor on two PCs in the room and power off the flat screen TV in the room. Still no relief. I removed and reconnected all connections on the

Re: [Elecraft] P3 SVGA interference -

I wonder if this discussion and suggested ribbon clips address my issue. I acquired my K3 this past summer and then a P3 off of eBay shortly thereafter. I installed the SVGA adapter a couple months ago and I have a problem which sounds similar to what is described in this thread. For lack of a

[Elecraft] Screen Magnifier for P3...user with poor eyesight

I just acquired and added a P3 to my K3. From all indications it works very well but I find that with my aged and failing eyesight the screen is quite difficult to read, for example, when setting Mkr frequencies and the center frequency in upper center of the screen. I'm thinking there must be an

[Elecraft] CBLP3y Cable P3 to K3 connection

I just acquired a P3, but was surprised to learn that I need a cable (CBLP3Y) to enable the K3 VFO frequency to be displayed on the P3. I located in my toy box a couple cables of same description as the CBLP3Y, that being they are terminated on one end by a RJ45 connector and a DB9 Male on the

[Elecraft] P3 wanted, used in good condition, or unfinished kit

I hope to acquire a P3 in good condition to add to my recently-acquired K3. I've considered ordering the kit, but not sure my failing eyesight is up to the task. The factory assembled model is a bit more than I can or need to spend, so I'd like to hear if you have a P3 in good condition which

[Elecraft] Using Heil Pro Set Elite boom mic on K3.. what adapter is required?

I am soon to be the owner of a used K3. I presently use a Heil Pro Set Elite boom mic for my IC-7600 and want to know if anyone here has used this mic on a K3, and if so, what adapter did you use to connect to the round 8-pin mic input on the K3? I'd like to hear your ideas. Thanks Mike, K5MP

[Elecraft] KAt100 power on question

I recently purchased a used KAT100. Not sure how to interpret a possible failing condition at Power UP time. Stupid Question: If I simply connect 12VDC to the DC power input jack on the KAT100 (without the K2 physically connected), should I see the lights eliminated on the KAT100? Reason I ask

Re: [Elecraft] [K2] KPA100 Temp Cal: Room temp or radio temp?

I have a related question: I purchased my K2/100 only a month ago, second hand, SN 5818. I've experienced "PA HOT" shut down on several occasions when running 100Watts out, and less frequently but it has happened when at 50Watts. I've witnessed the discussion of setting Cal tPa to ambient temp.
