Re: [Elecraft] KPA1500 Linearity
I'll have to make some more measurements, but Paul's seem to have much less gain compression than mine. (0.6 vs 1.4 dB from 1 kW to 1.5 kW) That's also closer to the specs for a pair of BLF88XR's. 73, Scott K9MA -- Scott Ellington --- via iPad > On Jun 15, 2018, at 11:24 PM, Paul Baldock wrote: > > I received my KPA-1500 yesterday (#244) and did some linearity tests today > > 14.2MHz, Dummy Load, ATU Bypassed.

Re: [Elecraft] KPA1500 Linearity
I received my KPA-1500 yesterday (#244) and did some linearity tests today 14.2MHz, Dummy Load, ATU Bypassed. Using KPA-1500 internal Power Meter. Continuous carrier. 10W drive, Gain = 15.6dB 180W 15W drive, Gain = 15.8dB 20W drive, Gain = 15.9dB 25W drive, Gain = 16.0dB 1.0KW 30W drive, Gain = 15.9dB 35W drive, Gain = 15.7dB 40W drive, Gain = 15.6dB 43W drive, Gain = 15.4dB 1.5KW 45W drive, Gain = 15.4dB 1.57KW Based on this it look like about .6dB compression at 1.5KW. I think that's pretty good for an SS Amp. I also measured the gain on all the bands at 1.5KW out. Drive varied from 31W on 80M to 47W on 15M. or 16.8dB to 15.0dB. That amount of variation is rather disappointing. I also noted that the internal power meter is pretty inaccurate at low levels. For Example at 50W on 20M it reads 43W. Its pretty close above 300W and right on at 1.5KW where its calibrated. I would be interested to see any data that others have collected. - Paul KW7Y At 02:26 PM 6/14/2018, K9MA wrote: The gain compression I measured, between 1000 and 1500 W on 40 meters, was 1.4 dB.

Re: [Elecraft] KPA-1500 received and installed
FB John, Mine arrived today. Unfortunately I’m in Colorado getting ready to activate a SOTA in the morning with a kx2, so I won’t get to install the kpa-1500 until Sunday. Wait this is not unfortunate, getting outside with a kx2 is a good thing. WG0AT and I will be activating W0C/SP-081.

[Elecraft] K3 local and K3/0 mini remote
Hi Folks, I thought I had this figured out. I have the K3 with the KIO3B with the P3. I have the factory cable as well. I want to be able to operate in the shack and with the K3/0 mini remotely. I know I can do it by swapping one cable. How can I do it with out swapping cables. I have the Control RCC with the Squid cable to the K3/0 mini. The Radio RCC is connected to the K3 via the TXVR port on the P3 when remote. I have a diagram that I used and thought worked. Something changed and no idea what. If you can help me out, I would appreciate it.

Hi Fred, It's called a sequencer. Individual reels of tape and reel axial parts are loaded in the sequencer. So there would be an entire reel of 10k resistors, a separate reel of 100k, separate reel of diodes, etc. The sequencer then removes the parts from the tape and creates a new tape with the parts in the proper order and count. The sequencer my company used to have would also measure the value of the part and reject it if it wasn't in the tolerance window. I hope that all makes sense... Surface mount is oh so much easier.

Eric /elecraft.com/ On 6/15/2018 9:01 AM, Rick WA6NHC wrote: Codes are a only sets of standards that must be adopted (at the county level usually) to have the force of law. The codes are written by 'professionals' (sometimes cronyism sneaks in) who have spent a long time in the trades and have moved up (i.e. the NFPA is mostly retired fire chiefs). Codes are not universally adopted when printed and if they are adopted, may not be the most recent edition. That is up to the local controlling board (of supervisors usually). Many boards feel it necessary to 'review' (including modifying for local 'concerns' be that expense or politics) the code year in question before adoption, and since they are renewed every couple years with that process being tedious, the adopted code may be many years out of date. Where I live, there is no code enforcement be it electrical, building, plumbing, whatever (but common sense requires following the code, so does the insurance company). There are no inspectors and no management for code enforcement even IF it was adopted. There is no budget to hire an inspector and one does not even whisper adding taxes here to create any of it. Putting up a tower is simpler, but I am requiring that the contractor follow the manufacturers documentation for the base and the power conduit and wiring are up to code. That way, it becomes part of the house coverage for the insurance. The next county to the south enforces building codes, so yes, your mileage varies. Then, not all contractors (even if licensed) follow the codes. Not all home inspectors (prior to sale) know what to look for as well. It is up to the buyer/owner to do their due diligence here. Mine was a good one, noted that the framing and roof were built over strong for added snow load for examples; knew the electrical and plumbing codes, he also caught the small things easily missed. But now you know how it may have been 'missed'. If in fact it was inspected at all; there may have been no adopted code to enforce by inspectors that don't exist.

Think of it like that and keep everything separate. Even though you will do a minimal build on the RF board for test purposes it's still 3 kits. It's not a one day build.

Go back read it again, ask on here. But that build book must have been worked over almost 8000 times, it's right. I couldn't find any suitable trays to organise components but I bought a set of small(ish) plastic pots with lids. Big enough to get my fingers in. I had 12 I think which was more than enough, about 4 inches diameter and a couple of inches deep. Keeping the lids on and marked with the contents helped keep from them scattering from a careless movement or other accident. Keep everything as Elecraft intended. If it came in a separate little brown envelope, inventory it then put it back in the envelope. Keep the resistors on their tapes, they are in fitting order.

Codes are a only sets of standards that must be adopted (at the county level usually) to have the force of law. The codes are written by 'professionals' (sometimes cronyism sneaks in) who have spent a long time in the trades and have moved up (i.e. the NFPA is mostly retired fire chiefs). Codes are not universally adopted when printed and if they are adopted, may not be the most recent edition. That is up to the local controlling board (of supervisors usually). Many boards feel it necessary to 'review' (including modifying for local 'concerns' be that expense or politics) the code year in question before adoption, and since they are renewed every couple years with that process being tedious, the adopted code may be many years out of date. Where I live, there is no code enforcement be it electrical, building, plumbing, whatever (but common sense requires following the code, so does the insurance company). There are no inspectors and no management for code enforcement even IF it was adopted. There is no budget to hire an inspector and one does not even whisper adding taxes here to create any of it. Putting up a tower is simpler, but I am requiring that the contractor follow the manufacturers documentation for the base and the power conduit and wiring are up to code. That way, it becomes part of the house coverage for the insurance. The next county to the south enforces building codes, so yes, your mileage varies. Then, not all contractors (even if licensed) follow the codes. Not all home inspectors (prior to sale) know what to look for as well. It is up to the buyer/owner to do their due diligence here. Mine was a good one, noted that the framing and roof were built over strong for added snow load for examples; knew the electrical and plumbing codes, he also caught the small things easily missed. But now you know how it may have been 'missed'. If in fact it was inspected at all; there may have been no adopted code to enforce by inspectors that don't exist.

Re: [Elecraft] AC Power for the Station
Old standard way of doing it. They used to use a solder pot and immerse the twisted wires in the hot solder. Then cover with rubbery tape and then friction tape.

Re: [Elecraft] K2 Build: Requesting Tips and Tricks
Scott, First, do not mix up the front panel, control board, and RF board parts when doing inventory, do each separately. Inventory the inductor bag contents separately as well - there is a 1mH RF choke that looks very closely like a 1k resistor. If you are not adept at identifying screw sizes, measure them (they are all 4-40 diameter). The best method of keeping the parts organized is to use the old "Heathkit" method. Seal up an empty USPS Priority Mail Medium Flat Rate Box (the 13.5 x 12 x 3.5 inch size) and you have 2 'trays' with cardboard corrugation on both sides. Stick the component leads in the corrugations. The center of the tray can be used to hold the larger items and hardware. I personally do not like muffin tins or plastic boxes for the hardware because I cannot get my fingers in to grasp them easily, but some folks seem to like to use them. 73, Don W3FPR On 6/15/2018 10:45 AM, Scott wrote: I'll be starting a K2 build in the near future after the inventory is complete.
