Re: [Elecraft] Strange behavior of K3 on FT8

You need to Hold down DATA MD and select the right data sub-mode. It is set per-band. DATA A is usually the correct sub-mode for FT8. This uses the USB mode. On 30m, you were likely using the AFSK A mode, which is similar, but uses LSB mode. AFSK A is used for RTTY, generally. > On Jun 19,

[Elecraft] Strange behavior of K3 on FT8

Dear OM or YL: Today I did a successful POTA activation using my K3. I usually use a smaller, lower wattage rig, but decided recently to use the K3 portable. I've used the K3 for POTA activation three times before this week -- but all on SSB. Today, I used FT8. I first was on 20M and

Re: [Elecraft] Strange Behavior on P3

Robin, I certainly have not seen that behavior, but recommend you go over the P3SVGA and P3TXMON option instructions. Are all cables fully plugged in, and are the cables dressed inside like what is shown in the diagrams? You may have to devise some kind of 'clip or support' to keep the

[Elecraft] Strange Behavior on P3

My P3 has started to exhibit some strange behavior since I installed the SVGA and TXMon options. Every time I turn the VFO A the P3 acts like it is being overloaded and the display shows interference. I have never noticed this before. Has anyone seen this behavior before? I am running a K3S

Re: [Elecraft] Strange behavior on K3 system when transmitting

Jerry, That is "just another data mode" to the K3. First, you may be better off using DATA A submode rather than USB because the compression is automatically set to zero and the TX EQ is set flat. That allows you to set your SSB compression and TX EQ as you wish for voice modes. Like all

[Elecraft] Strange behavior on K3 system when transmitting

Hello, I am using my K3, KAT500 and KPA500 in an MARS environment and I am having this problem. We use the M110A data mode to transfer messages between stations - sort of like FLdigi only the mode is not legal on amateur frequencies. When I use the M110A (Signalink is the interface and

[Elecraft] Strange behavior of P3

My P3 shows some strange behavior when combined with a K33 (newest firmware on K3S and P3): 1. When the subreceiver is turned on in LSB mode (listening to a qso on the low bands) and VFO B cursor is also on, the cursor VFO B changes from LSB to USB, if the mode of the main receiver is changed

Re: [Elecraft] Strange behavior of P3

Hi Paul, many thanks for Your info. It seems to me, the P3 under certain conditions displaying an USB cursor if the subreceiver is switched to LSB (Problem #1) is also a bug in the firmware ? 73, Martin Paul Saffren N6HZ schrieb: Hi Martin, Problem #2 is a bug in the P3 firmware. With

Re: [Elecraft] Strange behavior of P3

Hi Martin, Problem #2 is a bug in the P3 firmware. With the new K3S there are additional steps in both the attenuator and the preamp that the P3 is not taking into account. This will be fixed in the next P3 firmware release. kind regards, Paul N6HZ -- View this message in context:

[Elecraft] Strange behavior if P3 with K3

I picked up a P3 kit last week, put it together for FD. Took it up to Bonny Doon and had it in our CW station. We (several operators) observed a strange behavior. With the bandspread opened to 200kHz, and with noise floor ~ -130dB, there seemed to be a broad hump of noise on the upper half side

Dear group, Someone please explain to me what's happening with my K3. I have both main receiver and sub receiver linked. This way, I can tune the sub receiver with the main VFO knob. However, there's something weird going on when I cross some sort of band edge. For example, if both VFO

Re: [Elecraft] Strange behavior when tuning around with SUB receiver LINKED

Another thing I noticed that when near the 5Mhz band, other knobs like the filter knobs will also induce this motorboat noise when turned. Any suggestions on how to fix? 73, James KC2UEE Also, and possibly another more concerning issue is that when the sub receiver is on, and I'm tuning

Re: [Elecraft] Strange behavior when tuning around with SUB receiver LINKED

James, What rev of firmware are you using? I went through test on all of them I could with the subreceiver, which I didn't install until 2.72 was current. I can't duplicate your results with 2.82. It may not be a firmware-related issue (or issues). In the first problem statement, it sounds

Re: [Elecraft] Strange behavior when tuning around with SUB receiver LINKED

My K3 does this sort of unexpected leap to next band up/down at tuning breaks with linked or unlinked main/sub. I assumed this was because I had the general coverage filter in the main but not the sub. Firmware 2.82. No 'zipper' noise here except that little bit at the bottom end of 6m. 73

[Elecraft] Strange behavior when tuning around with SUB receiver LINKED

James, I, too, have noticed what I believe you are noticing. It seems to me that the jumps in the tracking of VFO A and VFO B occur at the transitions of the bandpass filters. It is as if when the bandpass relays switch, the VFOs lose their synchronization. (Of course, I could be wrong,

Looks like I may not be sticking to my explanation after all. Try this and see what you get: WITHOUT the SUB Receiver linked, tune the main receiver to 6.000.000 MHz. Be sure you can see the frequency of the Sub Receiver on VFO B area and the tuning rate is FINE. Push AB twice to

Hello all My K2 has begun to flash back and forth between power reading and frequency. When the power setting is above 10 watts KPA ON I assume. When you change the vfo it will flash between power and Freq sometimes. Also with the power display showing it only reads 68 watts flickering 69 watts.
