You can install PEM nuts with a hammer and anvil but it's best to do it with a PEM insertion machine or a fixture in a press. 4-40 nuts typically require a .166 diameter hole and 6-32 require a .188 hole. John KK9A Michael Blake K9JRI wrote: I am waiting on a response from Elecraft TS on this

[Elecraft] Fw: KPA500 Power out query.

Is there a fix for the KPA500 pinging? I do not use my amp often but I have seen this occur on occasion. I am hoping that the KPA1500 does not do this. John KK9A AJ8MH wrote: Sun Jan 28 12:30:32 EST 2018 Also, heat causes some stress on the chassis and you'll here pings as it flexes with temp.

[Elecraft] Y-BOX v1.3 Closeout Pricing; New Y-BOX v2.1 Now In Stock

I have original versions of the Y-Box. Although it worked, I never liked using multiple Y's on the ACC jack and this box eliminated the clutter. Both of mine work perfectly. Also Bob is very responsive and a great guy do business with. I assume that the amplifier port has certain terminals not

[Elecraft] K3 Power Drop During Operation

This first thing I would do is check the voltage at the radio. There is a voltmeter in my K3S so there probably is one in the K3. You could have a power supply issue or just low voltage in Curacao. I try to maintain 13.5V on TX. John KK9A K8ND wrote: Thu Jan 25 06:54:48 EST 2018 I was running

[Elecraft] Array Solutions Lightning Arrestor

Until K9YC's post I was not aware of the Array Solutions lightning arrestor. They appear be a nice product. How do GDT's fail - open or closed? If open, how do you know that they need replacement? John KK9A K9YC wrote: I strongly agree with Bob's advice, EXCEPT that I've gotten really tired of

[Elecraft] KPA1500 notes

These are excellent reviews, I especially liked W0YK's comment about having to consult the wattmeter to confirm that it was running. This would have been the perfect amp for Ed to bring to Sabana Basora, Aruba for the 2018 RTTY Roundup. Are any stations outside California testing the KPA-1500?

I set both of my K-PODs to switch to specific bands. I am not at home now or I would copy the programs however it was easy to find in the manual. If you cannot find it I can send it to you tonight. I used this feature a lot over the weekend, it is much nicer than pressing the up/down toggle on the
