[Elecraft] PTT keying a KXPA100 with a K2

Hi, I own a QRP-K2 with the KIO2 installed. I want to PTT key a KXPA100 (not KPA100). May I connect Pin9 from KIO2 (8V in receive mode and 0V in transmit mode) directly with the PTT-IN connector on the KXPA100 (5V receive, 0 V transmit) ? Maybe with a diode (cathode KIO2, anode KXPA100) ?

Re: [Elecraft] [K3] Locking VFO B

That's what I thought. But I got a response like this: [MAIN], and it didn't do anything. Maybe the fact that I was in diversity at the time had something to do with it. I'll turn off diversity and try it again. 73, Victor, 4X6GP Rehovot, Israel CWops #5 Formerly K2VCO

Re: [Elecraft] [K3] Locking VFO B

Yep, looks like that’s either a bug or a feature. When in diversity mode and BSET using LOCK gives the same response as RX ANT. Maybe what it’s trying to say is that you can’t lock B because it is already “locked” to VFO A . Ken K6MR From: Victor Rosenthal 4X6GP

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

The point is that protection is built into the tuner & the firmware to take care of extreme instances. As I recall, one release a few years back stated that it will handle the parting of an antenna wire while transmitting at maximum output. We can assume that a non-resonant antenna is not

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

Regardless of what happens to the tuner, the better the untuned match, the less power you lose in the matching network, and the more power goes out on the air. 73 Bill AE6JV On 12/13/20 at 10:02 AM, pu...@af2z.net (Drew AF2Z) wrote: But as someone else has mentioned-- choose an optimal

Re: [Elecraft] PTT keying a KXPA100 with a K2

Luc, The short answer is that will not work. What you need is an open circuit on receive and a short to ground during transmit. Take a look at the K2(BASIC) External T-R Relay Driver on Tom Hammond's (SK) website http://www.mmccs.com/mmarc/n0ss/index_k2.html. Kits are now available from

[Elecraft] Ice on dipole under snow under ice

Before I try something crazy, like climbing up on the roof ... . We had an ice storm.  The ice pulled my wire dipole down to the roof, but didn't break it because one mask was Schedule 30, which leaned over nicely.  It then snowed on top of the ice. I've been able to free the feedline

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

Examining the KAT3A circuit board, I doubt it can handle more than 1000 volts that a worst case random wire -- or a fault -- could cause at the output of the KAT3A tuner when the K3 is producing full rated output. But its unlikely that the KAT3A can produce full rated K3 output because of

[Elecraft] A question about QRQ

A question about QRQ mode . . . I recently read a comment about the fact that QRQ cannot be used when the K3 is operating in RIT, XIT, or split, nor with DSP shift. Because I believe, though I am not certain, that the discussion was about whether this incompatibility exists in the K4, I was

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

I can’t help but think we’re over-thinking this. I think the original post was regarding ‘portable' operation. When I go portable I don’t carry a large antenna with lots of wire or weight. I usually carry a 41’ (non-resonant) wire with a 9:1 unun rated at 300w watts, and a throwing line and

Re: [Elecraft] Internal tuner with random wire

Sure if you have the time and supports, but if you are setting up a temporary station for a few hours you don't want to waste operating time. A 9:1 or even 4:1 unun can get you on the air quick. Need only 1 support. A counterpoise and a choke of some kind on the feedline does help. On Sat, Dec

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

I think you just proved my point. The KAT3A does not have a lower power rating for larger SWRs. That would indicate that it can handle the rated power over the entire rated SWR range. If extreme SWR at full power would exceed the component ratings, the specs would say that. This is the entire

Re: [Elecraft] Ice on dipole under snow under ice

I haven't given this a lot of thought but: 1. Virtually none.  100W most radiated, leaving very little heating the ice/snow along your long cold wire. The wire itself won't heat up as it has very low resistance. 2. IDK about the KXPA100, but Tune is often done at low power, so if 100W work,

Re: [Elecraft] 10 METERS IS OUT

That may be why you didn't hear much. At this point in the solar cycle, most propagation on 10M is not very strong, so it takes the 10 dB or so advantage of CW over SSB to make many of the QSOs. I'd guess that half of those I made on CW would not have been possible on SSB. One of my buddies,
