Re: [Elecraft] K2 RF Speech Processor?

Hi Karl, A question. Does the K2 have a variable resistor at R! Compression ratio set? Yes, the resistors RP5 are the 'variable' resistors for compression. Yesterday I had send a mode for other compressions. With other resistors you make your own three compressions. 73/72 de

[Elecraft] KX1 - comparison of internally-mounted batteries

I've posted a chart at the link below that compares the best AA chemistry (Lithium) to a pair of rechargeable LiPo batteries that are perfectly sized to fit in the same space inside the KX1's lower case. I also periodically took RF output readings of the rig during various points on the

[Elecraft] Nylon Screw

The nylon screw is the ultimate answer...The reason the short occurs is that in some instances the tapered head of the screw comes into contact with the sides of the hole in the tab of Q6...Counter sinking the hole in the tab of Q6 works as a temporary measure, but I would not recommend it as a

[Elecraft] Rework Eliminators

For some time I had been aware of the Rework Eliminator kit from Unpcbs for use in the K2. At the time I could see no real use for me. However having built my K2 and used it for some time I felt I wanted to restore it to its original state to carry out some initial alignment checks and compare

Re: [Elecraft] Rework Eliminators

I agree wholeheartedly. I recently had problems with the KSB2 and 160 meter mods. It was great to be able to do A/B comparisons and troubleshooting simply by unplugging the offending module and plug in the header PCB. Mike AI4NS For some time I had been aware of the Rework Eliminator kit from

[Elecraft] K2 C71 C174

Hi Having successfully build a K1 and a KX1, I have finally bitten the bullet and gone for the fully monty. My new K2 is going together fine, except I can't find the 82 pf capacitors C71 C174. I know Elecraft will send them to me, but I would like to keep up my momentum. I live in the greater

[Elecraft] K2 4907 - Still no audio

Fellow builders, I've been working on building my K2 as time permits since may of 2005. I was hoping to have it completed by now, but got stuck on a problem and haven't had the time to really delve into it until recently. Back in 2005, I posted a question to the group - the topic was No Audio

[Elecraft] AWG Packet Engine?

Has anyone had any luck using the AWG Packet Engine software for HF packet with their K2? I just cannot seem to get tuned in well enough to decode packets. Even on the OP1 filter, I am thinking that I am just to close to the edge of the bandwidth of the filter to receive. Any ideas? 73, Bill

Do I really want to put an LiPo battery *inside* my KX1? When I used one, I specifically put a pigtail and coax pwr connector on it to keep it outside (and thus be able to fling it overboard if it burst into flames). Fred K6DGW KX1 #897 Fred, I don't know if you do or not. I guess you'll be

RE: [Elecraft] K2 4907 - Still no audio

Zac, If D9 has DC Voltage on the cathode, either there is RF on your antenna or you have something wired wrong. Does the voltage at the cathode of D9 remain if you disconnect the antenna? Do you have any DC voltage on the anode of D9? That should be zero volts. Are you certain the K2 is not

Can't help on the AWG engine, but I'm able to use RTTY and Slow Scan TV ( At least receive). I'm using the MMSCTV and MMpkt drivers. They are a sound card implementation. I enabled the RTTY mode -- the 'r' mode using the secondary menu commands. Using Spectrogram, I set the filters fairly

[Elecraft] K2 Menu/Filter Settings Downloadable?

I'm getting ready to upgrade my K2 firmware to version 2.04. According to the instructions, I believe I will have to manually reenter all of my menu and filter settings once I install the new cpu. The instructions say write all the info down, which is going to be time consuming and which will
