Re: [Elecraft] Looking for an old version of Spectragram

Thanks to all who either sent me installs or pointers. The version on Tom's (N0SS) page does indeed work. Not sure what the issue is with 14, but 5.1.7 works fine. Thanks again, Bill W1PA K2/100 #61 -Original Message- Not because it was freeware, but because it worked with my old com

[Elecraft] Looking for an old version of Spectragram

2006-11-05 Thread Bill Acito W1PA
Not because it was freeware, but because it worked with my old computer in my shack (Win98SE and an old SB AWE64 card). It appears version 14 does not. Anyone have one (an old install)? Bill W1PA ___ Elecraft mailing list Post to: Elecraft@mailman.

Mike, I notice the opposite (but when running full power: 100-110W). The first couple of syllables are lower, and then it kicks up. I'll try reducing power and see if it goes in the other direction. I was told that the previous effect was normal (action of the ALC). Bill W1PA K2/100 #61 __

Re: [Elecraft] KDSP2 - artifact

2006-10-31 Thread Bill Acito W1PA
One other point to sanity check -- have you put the DSP in "bypass" and confirmed that is the cause? What I thought might be DSP artifacts turned out to be issues with RFC15 (see my earlier thread about tuning warbles) Bill W1PA ___ Elecraft mail

I should also mention that I am getting ALC indication at full power (one LED bar only). So next question... anyone recommend electret-based mic's (since the Elecraft hand version is no longer available)? (I'd like to try that first before additonal mods) I have a wealth of Ten Tec equipmen

RFC15 supplies the 5V to the VDD pin of the MC14570... how can there be 4.23V at the pin if RFC15 is open and there is no other VDD pin on the IC? I'll answer my own question: apparently, very easily. Power-off DC resistance check confirmed that the RFC15 was open. No visual indication of

Update. 1. Tom (N0SS) suggested I redo the CAL PLL. Done. No effect. 2. Jim (K4ZM) suggested I Check the resistance of the small 100uh rfc that you added between 16 and the +12 volt line. I have seen this same problem when that RCF is open. It is a very delicate choke and very easy to br

After a few months of relative inactivity, I went back last night to continue building my KPA100, and had the K2 on in the background. I actually thought it was a DSP artifact, but it's there even with the DSP in bypass. Tuning through a quiet band, I noticed as I tuned slowly across a CW signa

[Elecraft] FYI: Nice LCD Display Modules

Thought I would share this... came across some nice LCD display modules (voltage, temp, elapsed time, etc.) while looking for something to add to my A&A UC3906 Charger for charge monitoring. You can get big LED displays modules on eBay for $10, and these are certainly not cheap, but they are smal
