[Elecraft] Wow, Here is an example of why Elecraft is leading the pack.
I have connected a Steppir antenna to my K3. The Steppir frequency and band tracking of the K3 works fine when I am using my logging program. It also works fine after I send an AI1; command to the K3 using the K3 utility. I can then shut off the computer. But when the power is cycled on the K3, the K3 turns off the broadcast status command. So I would have to boot the computer and resend the AI1; command to get the Steppir to track the K3 without the logging program running. So to get the AI command to not reset during a power cycle, at 12:44 PM today I sent a request to Elecraft support, along with my rationale. At 1:25 PM today I received a note from Gary Surrency that said he forwarded it to Wayne for his consideration. At 1:29 PM I received a note from Wayne that he just added it to his short list. At 7:29 PM Wayne sent the following email: "John, I just made the AI parameter "sticky" so you won't have to do it on each power-up. You'll have to set it one time; this can be done using the "Command Tester" screen in K3 Utility. The changes will appear in revision 1.57 (or later), which isn't yet released. Watch for the announcement. 73, Wayne N6KR " Now I had high expectations, but less than 7 hours elapsed time from suggestion to incorporation in an upcoming release. WOW! 2008 is going to be a very good year. Aloha, John Buck KH7T ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] RTTY and filters
Depends on what you are up to. For S and P with a soundcard 200 Hz sounds to tight. The signals have a 170Hz shift and many stations still work with a 200 Hz Shift. I used the standard filter narrowed down to aprox 700 Hz. Was OK for me When some qrm comes up, switching to the 400 Hz filter For Cq-ing your qso partner have to be exact on QRG with the 200 Hz filter but eliminates all others..

[Elecraft] K3 Bandstop Filter Schematic
I'm not yet an owner of a K3, but I have been studying the schematic package to learn as much as I can about the rig. On the RF Board schematic, sheet 1 of 4, upper left border of the page is an apparent multi-pin connector is labeled as "Z3 Stop-Band Filter." The next sheet after all of the RF Board schematic sheets is a schematic called "Bandstop Filter." I'm assuming this is the circuit that interfaces with the Z3 connector. But I can't figure out how the Bandstop filter would connect electrically to Z3! Could someone educate me? Of course, that may be a lost cause! :-) Thanks in advance!! 73, Phil Westover, WA7URV (K1, K2, KX1, and a K3 not too far away!) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] RTTY and filters
Mike, My concern is that the 200 Hz filter might be too tight. With 170 Hz shift and 45.45 baud, the minimum bandwidth would be around 225 Hz (right at the rated - 6dB point of the "200 Hz" filter) and probably closer to 310 Hz to maintain some of the "sharpness" of the shift. Lyle or one of the other DSP folks would know the minimum necessary bandwidth better that I do. However but since the 200 Hz roofing filter is not selected until the DSP bandwidth 200 Hz or less it would be safe to suggest that a full 200 Hz configuration might be a little "too tight." I would think the "250 Hz" filter with its 370 Hz -6 dB bandwidth or even the 400 Hz filter with its 455 Hz -6 dB bandwidth would be more appropriate roofing filters for RTTY than the 200 Hz filter. 73, ...

[Elecraft] XV222 Problems- More Info
Hi Gang, Yesterday I posted about troubles following building a new 222 transverter. While probing TP5 in transmit I only had 3.5mV instead of the normal range of .1 -10V. Today I checked all voltages listed in the Owner's Manual and the only other voltage out of spec is that the output of U1 on transmit goes to zero. It should be 3 - 6 V on both xmit and rx. I brought home from work a Tektronix 100MHz scope but the manual has no RF voltages. Any ideas?? 73, Mark K2QO/R ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K2 - 40m transmit problems
Zac, For the bad voltages on Q19, look carefully for a bad solder connection on RFC14 (poorly tinned toroid lead perhaps?) and/or R20. The resistance measurement from Q19 source to ground should be close to 270 ohms. Note that this condition may or may not be related to your HiCur situation. As for the HiCur message - is that message present when transmitting into a dummy load? Does it occur at all power levels? Is this the base K2 only or does it have the KPA100 installed? Do you have the KAT100 also? If you have the KPA100, has it been updated with the KPA100UPKT - if updated, was C31 changed to 0.22 uf during the upgrade? Many questions that I must know before venturing an intelligent comment. 73, Don W3FPR Zac Brown wrote: I'm getting HiCurr messages when I transmit on 40m, the bargraph shows multiple bars lit, and I can hear a very faint squealing sound coming from the K2 when I transmit.

Re: [Elecraft] KPA100 D16/D17 still blowing
Bill, That is not normal - BUT - Before I can offer a single suggestion, can you say whether your KPA100 is the older T/R switch design or is it a KPA100 that shipped after Nov 2006? If it is the older design, has it been updated with the KPA100UPKT - and if it has been updated, was C31 also changed to 0.22 uf? *If* you have the older T/R switch design, there is a possibility of a parasitic that can show up during tuning, particularly on 40 meters. With the new design, *if* C31 was not changed to 0.22 uf, there is a possibility of a low frequency oscillation that shows up when operating on 160 or 80 and sometimes on 40 meters. It might be possible for an oscillation to create a sufficiently high RF voltage to zap the diodes during a tuning cycle of the KAT100. (Note that there are many 'ifs' here, thus the reason for the questions to be answered - it depends on the level of your KPA100). If your KPA100 is the older design, I suggest the KPA100UPKT may cure the diode zapping, but if you already have the update (including the new C31), then there is some other problem. 73, Don W3FPR Bill Carpenter wrote: Hi all, Since adding a KAT100 to my K2/100 about a month ago D16 and D17 in the KPA100 have blown 3 times. The first time I thought it was caused by antenna static buildup during a blizzard but the last 2 times it happened as the tuner was attempting to tune an antenna. Could there be problem with the tuner that is causing this? Everything is well grounded and the antennas are not bedsprings but a G5RV and twin sloper.

Never a complaint, and the oldest install is just over 7 years in operation now. Digikey and Mouser both stock Artesyn, and there is room in the chassis for it. Just a thought. Pick a DC-DC converter for the 8 to 16 Vin range, to give 48VDC out. Get the power rating that applies to your mic.

Re: [Elecraft] ARRL RTTY Roundup
The 7040, and 7080-7125 has existed for some time now as an existing ":Gentlemen's agreement". The 7040 spot was specifically provided for working DX in Region 1 where these people cannot operate above 7100. Ditto for the 20 meter band from 14070-14150 etc. This band plan was specifically provided to keep CW stations off the 'digital' frequencies and RTTY stations off the CW segments that are being frequently invaded by RTTY contesters. Yes the FCC allows what you say, but is is bad form and "hogs" the entire CW sub-band during a RTTY contest. That is the whole idea of seperating digital and manual CW areas of operation. If it was once a year there would be no problem, but the RTTY contests seem to appear every other weekend nowadays. I have no problems with contesting as such, but one mode shouldn't occupy the whole sub-band for frequent contests. Take for example the CW QRP groups and the SKCC and FISTS CW groups. They specify a narrow band to be used by the contests leaving the rest of the band for non-contesters or DX hunters. Most of the other digital modes (except RTTY) seem to stay inside the Gentlemen's Agreement bandplan. Why don't the RTTY contesters do the same? Unfortunately, a lot of the RTTY crowd seems to think they should have the whole CW sub band for their contests and ignore any bandplan that gives a "RTTY free" area to go to for CW communications (besides the WARC bands!) IS this too much to ask? 73, Sandy W5TVW - Original Message - From: "Mike Fatchett W0MU" <[EMAIL PROTECTED]> To: "WA7CS" <[EMAIL PROTECTED]>; "Elecraft Discussion List" Sent: Monday, January 07, 2008 12:23 PM Subject: Re: [Elecraft] ARRL RTTY Roundup 30m was not used in the RTTY Round up. Just where would you like the RTTY stations to go?

The Roundup was for 24 hours and the RTTY operators used lots of bandwidth that for the most part goes unused. There are always a few hams that seem to think they own certain frequencies and get upset when they are used by other amateurs for other purposes for brief periods of time. I guess the fun of the many have to be sacrificed for the few? Riley Hollingsworth, Chief Counsel for the FCC, spoke at great lengths about this type of attitude the last two years at Dayton. I think you can find it at the ARRL site or even on Youtube or other ham web pages. It is worth the few minutes of time to hear what he has to say. The extra portions of the bands were for the most part RTTY free. Many amateur bands did not have any contest activity on them at all. 12, 17, 160, 60, 2, 6 etc. There were plenty of CW signals to copy outside the RTTY areas. I suspect your complaints are not targeted at just the RTTY crowd but probably at contesting in general. This same contesting that gets people to use 10m at the minimums and utilizes a good portion of our bands on a regular basis which helps keep our claims to these frequencies. This same contesting group which is a huge buying force in Ham radio and a huge force to bring on new ideas and rigs such as the K3. RTTY is one part of the hobby and so is SSTV, QRP, SSB, AM, PSK etc. If contests are that troublesome find a non contest band or simply turn off your radio for the weekend and mow the lawn etc. On 1/7/08 8:40 AM, "WA7CS" <[EMAIL PROTECTED]> wrote: After a week of building a new K1, I was anxious to try it out and get on the air.

Re: [Elecraft] XV50 on 70MHz
I am making good progress. I managed to find an XV50 locally to do a trial conversion. I will end up with two but perhaps someone will want one of them. It has taken 5 hours because I was also writing the documentation which will be on my web pages. So far, I have managed to get the receive side working. I have converted the LO to operate at ~42 MHz with a 3rd overtone crystal and inductive tuning. My LO is actually 41MHz as I only had a crystal for that frequency. I have re-tuned the LO filter and see a nice clean signal on my scope. To bring the converter into band I only changed the resonator and input/output capacitors in the mixer band pass filter. The coils should really change too but will be very tricky to remove. Currently as a result the filter is a little lossy and not very sharp. I have not yet modified the front end preamplifier, I found it almost tunes with minimum C1. It works well enough to allow me to receive signals on the band, limited by band noise. I will look at improving the preamplifier but so far have left it alone to avoid the risk of damaging the FET. Conversion gain, 70.25MHz to 29.25MHz is 24 dB. Later in the week I will start to pay attention to the transmitter side and replacing the PA module and low pass filters.

RE: [Elecraft] RTTY and filters
I just checked the filter plot at http://www.elecraft.com/ . Strange that they call it a 250 Hz filter because -6 dB BW is actually 370 Hz, compared to 435 for the 400 Hz filter. At -60, the "250" is 785 Hz wide, compared to 935 for the "400" one. IOW, the 250 should pass all the 170 shift sidebands OK, because it is not really that narrow. Not really much difference between the 250 and 400. Jerry W4UK At 02:20 PM 1/7/2008, J.

Just to check, I tuned in Radio Aussi on 7240kc, with a different radio even. It had a booming signal. Just no hams on the CW portion of the band. :-( Imagine my delight this weekend when I plugged in my radio to the antenna again, RTTY all over the place.:-) It was so crowded they were pushing down into the CW part of the band. SO there are still home hams out there. How refreshing. How delightful. Correct me if I am wrong, but There are no lack of places for a CW operator to work? CW is allowed ANY where in the Ham band?

I suppose various antennas go by the same name, even though their operation is considerably different. I was referring to a Normal Mode Helix also known as a "Side Fire Helix". It's described in the Antenna Engineering Handbook (Johnson), and used in horizontally and circularly polarized omni-directional applications (mostly VHF and UHF-TV broadcast). It's a traveling wave antenna where the helix is wound around a supporting vertical mast that serves as a reflector. Axial mode helices are a different beast. They are typically used to provide broadband, UNI-DIRECTIONAL, circular polarization (OSCAR satellite communications). Invented by John Kraus, W8JK. I always considered a "rubber duck" to be nothing more than a continuously loaded monopole, and is considerably different in operation from the other two helical antennas described above. > > When Skin Effect losses become an issue in RF conductors and > > inductors, Litz wire is typically used.

Look at some of the older antennas used for FM broadcast, such as the Collins or RCA ring dipole arrays. These are physically short, capacitively loaded, gamma matched dipoles. Some implementations of these antennas place a number of identical dipole rings in parallel with one another to reduce ohmic losses and improve efficiency. These antennas may not be made from Litz wire, but the underlying concept of distributing RF current among closely placed parallel conductors in an effort reduce resistive losses is still the same. 73, de John, KD2BD Visit John on the Web at: http://kd2bd.ham.org/ . . . .

Re: [Elecraft] K2 and wire antenna
David Do you mean "close to resonance" or close to 200ohm impedance ? This is where the truly balanced matching units come into their own, but does anyone make them? David G3UNA Cobra Ultralite (www.k1jek.com) and the other is a 40 meter inverted Vee fed with 300-ohm twinlead. The tuner/balun has been able to match the first antenna on 160 to 10 and the second antenna on 40 to 10 (and even 80 but I never use it there). The balun has always stayed in the 4 to 1 position. I try to keep Especially in the 4:1 configuration, this sort of configuration will only work if the antenna is close to resonance. If the antenna is well off resonance, the path of least resistance for the RF will through the balun windings, which are a DC short, and will be an RF short if their reactance is not greater than that of the antenna. Such a configuration may appear to tune, but won't actually put much power into the antenna. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] ARRL RTTY Roundup
30m was not used in the RTTY Round up. Just where would you like the RTTY stations to go? The ARRL band plans suggest...Suggest the following for normal everyday use. 3570-3600 7040, 7080-7125 10130-10140 14070-14095 The FCC allows USA hams to operate RTTY on the following frequencies. 3500-3600 7000-7125 10100-10150 14000-14150 It appears that all this RTTY activity is clearly within the rules. The Roundup was for 24 hours and the RTTY operators used lots of bandwidth that for the most part goes unused. There are always a few hams that seem to think they own certain frequencies and get upset when they are used by other amateurs for other purposes for brief periods of time. I guess the fun of the many have to be sacrificed for the few? Riley Hollingsworth, Chief Counsel for the FCC, spoke at great lengths about this type of attitude the last two years at Dayton. I think you can find it at the ARRL site or even on Youtube or other ham web pages. It is worth the few minutes of time to hear what he has to say. The extra portions of the bands were for the most part RTTY free. Many amateur bands did not have any contest activity on them at all. 12, 17, 160, 60, 2, 6 etc. There were plenty of CW signals to copy outside the RTTY areas. I suspect your complaints are not targeted at just the RTTY crowd but probably at contesting in general. This same contesting that gets people to use 10m at the minimums and utilizes a good portion of our bands on a regular basis which helps keep our claims to these frequencies. This same contesting group which is a huge buying force in Ham radio and a huge force to bring on new ideas and rigs such as the K3. RTTY is one part of the hobby and so is SSTV, QRP, SSB, AM, PSK etc. If contests are that troublesome find a non contest band or simply turn off your radio for the weekend and mow the lawn etc. On 1/7/08 8:40 AM, "WA7CS" <[EMAIL PROTECTED]> wrote: > > After a week of building a new K1, I was anxious to try it out and get on the > air. > > Imagine my dismay when all I could hear was a racous cacaphony of RTTY > splatter from 7.025 to 7.100.

Re: [Elecraft] OT: Band Plan (was RTTY Round-up)
It would be VERY NICE if the digital bandplan was adhered to. The RTTY guys are some of the most flagrant violators and are usually all over all of what is/was the CW sub-band here. I have thought for years they should stay in the segment occupied by other digital (non-CW) modes. I always try and stay out of the digital areas with CW to keep from interfering with them, unless I too am using a digital mode (like PSK). The only digital 'bunch' I have seen outside the traditional Region 2 digital bandplan is European PSK. The area they use is very small and not usually a QRM problem. Not so with the RTTY contest folks! 73, Sady W5TVW - Original Message - From: "Matt Kastigar" <[EMAIL PROTECTED]> To: "Elecraft Support List" Sent: Monday, January 07, 2008 10:13 AM Subject: [Elecraft] OT: Band Plan (was RTTY Round-up) http://www.iaru-r2.org/band-plan/ -Matt W0XEU ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Any contacts that this fellow made here would certainly not count, since the rules specify 80, 40, 20, 15, and 10 meters only. Anyway, this part of the band is normally used for digital modes, so it's likely you would have this problem even if there weren't a contest. The QRP calling frequency on 30 meters is 10.106 MHz. I wonder what drives the ritty boys to swamp the traditional CW bands and wipe out the QRP calling freqs - oh yes, now I remember, the ARRL has deemed CW as non-relevant. Renewal of my ARRL membership is becoming less and less attractive. It really has nothing to do with the ARRL, except peripherally in that ARRL sponsors 8 contests per year (including VHF contests).

One I could hand-carry, but two is a bit much. Checked luggage is a crap shoot with TSA now. Even the TailTwister rotor, new in the box, that I had inside a suitcase, had parts and accessories removed from the factory packing and not returned but just tossed in the suitcase. I really don't want to subject my K3's to that kind of handling. However, the ICOM 756ProII's that we have down here worked great. Prior to the K3, it was my favorite RTTY radio. Ultimately, I'd like to have two K3's down here permanently, but let's not start another K3 availability thread over this comment! 73, Ed - P49X (W0YK) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 dimensions
>From previous postings
It's been brought to my attention that not everyone knows that the K3 has
*two* sets of feet. One set is on the bottom as you'd expect. But there are
also four feet on the *side* of the case (the right side looking at the
front panel) that work with a handle on the left side of the case for ease
of carrying and to allow you to set the rig down on its side without
damaging the paint or the surface you set it on.
When I spoke of the width with the handle and feet attached at 11.35", I
meant those side feet and the side handle!

Subject: [Elecraft] K3 Dimensions
Wayne asked me to post this in response to some queries from those who are
planning a specific location for their new K3.
The space required includes both room for the radio plus space for
connectors and, very importantly, cooling air flow through the rear and top
of the unit.
With the handle and feet attached, the overall width of the K3 is 11.35".
Overall height of the assembled K3 with the feet attached is 4.5" (with the
bail folded down for minimum height). In addition, recommend at least 0.5"
clearance on top for cooling air flow for a total of 4.5".
The K3 case is 10.1" deep (front to back), not including the connectors on
the back or the knobs on the front. The largest rear panel connector is the
SO239 ("UHF") antenna connector that requires an additional 0.5" depth.
Space is needed for the connector to attach at this point, plus routing the
cable, of course. The minimum additional depth for the antenna connection is
probably 1.4" for a right-angle connector. Connectors attached to the
multipin ACC and RS232 ports will also require additional depth. The
connectors typically supplied by Elecraft require an additional 2.25" from
the rear panel to the back of the jack screw. Similarly, straight-ling 1/4"
plugs for the KEY or PADDLE jacks on the back typically require an extra
depth of 2". A right angle jack may reduce that a bit. Of course there may
be audio connectors using mini audio plugs and control lines using "RCA"
connectors as well as a ground connection, but they do not require as much
depth as the ACC, RS232, Antenna, KEY or PADDLE connectors.
Keep in mind that air movement space is essential for cooling, especially
for the 100 watt version. The cooling fans are on the rear of the K3 and
require an unobstructed flow of air through the rear and through the holes
in the top of the case.
TO SUMMARIZE: A fully assembled K3 with handle and feet attached and cables
attached to the back will need the following space:
Width with handles and feet: 11.4" (minimum)
Height (bail collapsed) 5.0" (includes 0.5" for cooling air flow).
Depth: 12.1" minimum from the front panel, which includes a 2" space for
connectors in the back. The largest knob is the main tuning knob that
extends 1.1" from the front for an overall minimum front to back space
needed of 13.2" including clearance for the knobs on the front and room for
connectors to attach on the back.

Re: [Elecraft] ARRL RTTY Roundup
Hi tom: My first contest action with K3 #29 was the RU last weekend managed to be on the air for a couple of houres on 20 meters With a 50 feet long wire worked 18 countries and 12 US States from HB9-land Pretty frustrated that i could copy a lot of stations deep in the qrm/noise in RTTY but they didnt hear me.. must be a darn good receiver.. hi Next thing to do: put up a decent antenna. Hp to wk u in the next rtty test. Congratulations on being active in the RTTY RU. There were a number of stations I called but could not work either. I think much of the problem was they THEY were being called by many others as well and my signal was not the strongest of the bunch. I did not stick around many time to make multiple calls to a station, if I did not work him on the 3rd call, I moved on. I suspect that if I had been more tenacious at calling, eventually he'd have heard me and I'd have worked him... Ed, W0YK, was operating SO2R (two K3's) from P49X... from his QSO total, I suspect he may well have WON the entire contest...! I heard no QSO totals anywhere even close to Ed's 2500 Q's... at least so far. I operated without any external logging support, using only the K3's CW-to-RTTY conversion features and its internal RTTY decoding. Working stations was NO PROBLEM AT ALL... tuning them in using the K3's dual passband RTTY tuning option was as easy as anything and then having the exchange pre-programmed into a couple memories allowed me to just punch the button and go... when someone asked for a 'fill' I just sent it with the CW paddles and completed the contact. My 'effort' was something less than 'sterling' but I did knock out 20 or so Q's in a very short amount of time. Lots of fun. 73, Tom Hammond N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Kany: Dumb Question - Crystals
I am wondering what must be the good reason why kit suppliers provide crystals with two wires when crystals with three wires are available - the middle wire being connected to the external metal case, thus making earthing of the case a very quick, simple and safe operation. Every time I have to solder grounding wires to the case of a crystal, I get the nervous jim-jams, as I am afraid that I will damage the crystal by overheating, although I try to be ever so quick - a bit like my countryman, the late Errol Flynn. I guess the answer must be cost. 73 Kevin VK3DAP / ZL2DAP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] ARRL RTTY Roundup
Hi there My first contest action with K3 #29 was the RU last weekend managed to be on the air for a couple of houres on 20 meters With a 50 feet long wire worked 18 countries and 12 US States from HB9-land Pretty frustrated that i could copy a lot of stations deep in the qrm/noise in RTTY but they didnt hear me.. must be a darn good receiver..hi Next thing to do: put up a decent antenna.

Re: [Elecraft] Microphone capsule for K2
In a message dated 1/6/2008 6:21:57 A.M. Pacific Standard Time, [EMAIL PROTECTED] writes: I have a MH2, and going back and reviewing the SSB passband and filter alignment helped me quite a bit. It sounds fine, though I heard through another on the list that they had success with their Proset with HC5 without the preamp. I tried it out with a friend listening, and it worked just fine, and is now what I use. I do notice that it is impacted by the nearness of the mic to my mouth, so it would likely have more dynamic activity with a preamp, but I am driving to a full signal with the current setup. If you are not getting good reports with the MH2, then switching to another, similar mic (or even the HC5) will not help. First thing you need to do is check you passband, make sure they start at 300hz and then listen to both U & L sideband on another rig. - David Wilburn [EMAIL PROTECTED] K4DGW K2 S/N 5982 On Sun, 2008-01-06 at 13:29 +0100, Karsten Eppert (DK4AS) wrote: > I have purchased together with my K2 an MH2 microphone short before it > was discontinued two years ago. > The reports I receive always state, that the mike has too much bass. > The filters of my K2 were checked with spectrogram and - to me - appear > correct. > > In parallel I have tried a cheap boomset with an electret-mike.

[Elecraft] Elecraft Net Report for January 6th and 7th - Minor correction
Kevin - Just a note to congratulate you on being able to hear me on the 7045 KHz net yesterday evening. The band was way down here in TN and the QSB was rapid and deep. The minor correction is that I was on K3 serial # 175 for the net - my K2 (# 5540) was asleep and resting. As usual, 100 watts into my horizontal loop wire antenna. If it were not for the K3 DSP noise reduction I don't think I would have heard anything! Yes, good things come to those who wait - the K3 arrived in kit form on Dec 20th.

Re: [Elecraft] XV50 on 70MHz
I am working on it. My plan is to make as few changes as possible while maintaining adequate performance. This will be a compromise but should make it easier to modify existing units. I will put the instructions on my web pages (www.mike-willis.com) when ready. I have done the design work but I am now waiting for some parts to arrive before testing the modifications. The longest lead item is the 42MHz crystal. The most expensive new part will be the power module, though not for new builds as Elecraft are now using a MosFET module that covers 70MHz already.

Re: [Elecraft] dipole antenna efficiency
John Magliacane wrote: When Skin Effect losses become an issue in RF conductors and inductors, Litz wire is typically used. I see no reason why a One has to ask why this isn't used in all the commercial "miracle" antennas. I believe the Normal Mode Helix, as is used in HI-VHF television broadcasting, is a travelling wave antenna, rather than a resonant standing wave antenna, such as a dipole. You are thinking of axial mode helices. Normal mode helices are the most common antennas on VHF hand-helds, and are often called "rubber ducks". -- David Woolley Emails are not formal business letters, whatever businesses may want.
