Re: [Elecraft] Poor Man's Spectrum Analyzer
No trouble at all. I ordered the kit from Bruce Barlowe at The Science Workshop. http://www.science-workshop.com/ It's definitely not an Elecraft kit, you'll have to pick buy your own enclosure, power transformers, switches and front panel controls. The schematics are all hand drawn with no component values marked, but the parts list is complete. The assembly instructions are sparse, (install 16 resisters, install 14 capacitors, install 4 diodes, etc) but it will get the unit assembled. There is very little 'theory of operation' of the actual circuits, but the optional book offers lots of information on using the analyzer.

[Elecraft] New VCO Mod Kit
I have installed the VCO mod kit, and it works fine. I can now put my linear power supply next to the K2 without AC getting into the transmitted signal. I highly recommend this mod. BTW, this mod doesn't affect the passband or frequency, therefore no CAL FIL or CAL PLL is necessary. Nice mod, Wayne. Roy Morris W4WFBNo virus found in this outgoing message.

[Elecraft] K2 VCO SHIELD KIT
I received the K2VCOSHLDKT in the mail today. I just finished installing it. All went well. I did not have to adjust the turn spacing to get the voltages within range. Assembly was straight forward.

Re: [Elecraft] balun
Mike, The reason is that for small 4:1 baluns, you need more turns of wire on them to get the necessary inductance, more turns means a smaller wire to fit, and a smaller wire means the impedance of the two wire transmission line is not optimum for a 4:1 balun. You will have a high SWR just due to the balun. However, I have made many small 1:1 baluns using several turns of RG-174 on a toroidal core, by placing ferrite beads (12 FB43-801 beads work nicely) on the outside of a piece of RG-174, or just winding a bifilar pair of #22 enamel insulated magnetic wire on a toroidal core. You need a F114-43 or a F140-43 core to get enough impedance for 80 meters, although a smaller core will work for 40 up. Palomar sells a BA-58 bead kit for RG-58. Actually, a 1:1 balun works as well on a random length transmission line as a 4:1 balun. Unless the load is a predictable 200 ohms or there about like you get on an OCF antenna, the impedance of an open wire feed line is just as likely to be near than 50 ohms as it is near 200 ohms. You also can use a Low Power balun for 100 watts like the Elecraft balun kit, or the one on the NJQRP web site. DXE baluns are for high power, are large and heavy, and cost a lot of money. 73, Chas W1CG At 06:04 PM 10/11/2005, mc wrote: trying to get a little more out of this KX1 , I found a site on baluns, is anyone else listening in to the eham.net. there is comment on the balun pages that says there is no real good balun for low power, my question is why not, is it not the purpose to keep everything in balance to get the best out of your antenna no matter the power. the eham site does not offer any explanations on this but one HAM operator says DXE balms claim to fame is high power out puts. mike kb7dpc ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

If the balun is inefficient, the loss will be the same in DB at QRP or QRO. If the balun has a loss of, say 3 DB, then it will make your KW sound like 500 watts and your 5 watts sound like 2.5. Having said that, power loss is power converted to heat, so you might not notice a lossy balun when operating QRP; at QRO it would heat and possibly burn up. Finally, a balun may be more or less effective at reducing common mode currents (that is, converting between balanced/unbalanced), apart from losses. And one balun may have a wider frequency range in which it is efficient and effective than another. So there is definitely a sense in which one balun is better than another, even for QRP. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

We've just added two new Mini-modules to our Mini-module family -- BL2 Wideband 1:1 & 4:1 (Switchable) 250W Balun Our highly-efficient BL2 balun can handle up to 250 watts and can handles 1:1 and 4:1 ratios via an on board switch. It is very small (just 1.5 x 3") and lightweight, making it an excellent choice for both home and field use. It uses a special winding technique to reduce losses and extend the useful range, resulting in an SWR of less than 1.2:1 from 500 kHz to 55 MHz (200-ohm load). It includes rugged screw terminals for the balanced output as well as ground, and can be used in a variety of matching applications. Price: $34.95 Specifications: Power Rating: 250 watts maximum.Bandwidth: Input VSWR less than 1.2 when connected to a 200 resistive load, 500 kHz to 55 MHz. -- CP1 Directional Coupler The CP1 is a dual directional coupler that provides high directivity, can be internally or externally terminated and can be constructed with a coupling loss of either 20 dB or 30 dB. It can be used to sample a transmitter's forward power and reflected power output. As an example the forward power port can be connected to an oscilloscope for display of the transmit envelope. It is an ideal companion to the 2T-Gen 2 Tone test generator. For more advanced applications is can be used with a spectrum analyzer and tracking generator to sweep the return loss (SWR) of an antenna or other device in real time over a frequency range. Price: $39.00 Specifications: Frequency Range: 1 MHz to 30 MHz Coupling Loss: 20 dB or 30 dB (29.8) +/- 0.25 dB Directivity: 30 dB Power Rating: 30 dB coupler, 250 W; 20 dB coupler, 25 W --- For pictures and downloadable manuals, see: http://www.elecraft.com/mini_module_kits/mini_modules.htm Both items are in stock for immediate shipment. 73, Eric WA6HHQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

DOH! - It all seems so obvious now - for one thing, I could not use my existing control cable (without the KIO2) because the barefoot K2 has no place to plug it in! I now understand that: (1) the KIO2 includes a new DB9 connector for the barefoot K2 rear panel, and (2) that one of the functions of the KIO2 (in addition to level shifting, etc, for computer control) is provide an internal interconnnection for the AUXBUS and other control signals from Control Board ribbon cable connector of the barefoot K2 to the new DB9 connector, from which the signals can be conveyed (via control cable) to the KPA100/KAT100 in the new box.

Re: [Elecraft] Hi current/low power out on 20 meters w KPA100
Gregg, The problem appears to have been a batch of 1.6 ohm metal film resistors (R19,20) that had 6 turns and produced a weak 10MHz or thereabouts trap with C80,81 (4700pF). I believe Elecraft have sourced some resistors with lower inductance. For the Brits, locally obtained Vishay resistors (Farnell Part No; 550-012) worked. I could only get 1.5 ohm in 2W power rating but they had 1.25 turns and therefore only 1/23rd of the calculated inductance. After fitting I reset the drive bias. The problem was initially identified by changing C80,81 and a temporary cure effected by increasing the values to 5600pF or, in some cases, 6800pF. Scott at parts has the best American solution. 73 Ted G7BQM K2#4732 On 11 Oct 2005, at 01:54, Gregg W6IZT wrote: What was the final resolution to the high current/low power out condition?
