Different strokes for different folks
Michael McEwen
Not to say it is the best solution, but my evolution in amateur/qrp radio is this: I have a decent 100W base rig and a hex beam for 20 and 17...plus dipoles for 80/40/10. That is a good set-up for me...I'm not a "contester" or super-serious DX person. When it comes to portable ops, I have invested a lot more time and energy (and $) trying to get the best set-up for me. The Yaesu 817 was great...but it was hard for me to operate due to the small display/buttons and it had a bunch of capabilities that I never used. Fortunate for me, I sold it for about what I paid for it...5 years ago...much more pricey now. I never considered Elecraft, not because there is anything wrong...they are great but $, whoa. I have ended up with a simple LNR LD-5 CW/SSB 5 Band and a couple of kit 2-3 CW watt-ers. Two antennas for hiking/biking/camping: Alex Loop and LNR-PAR "trail friendly" 40/20/10. To reiterate: the 817 ( and other Yaesu 8XX) are great radios as is the Elecraft KX-3. If money, simplicity, and weight are not the issue, consider them...and a Buddipole multi rigged antenna. As an OM who is now a true OM (67 yr old), I'm going for simplicity, low weight, and fun. _ _ ... .. _ _ _ Doc K5OSA - QTH: EM04sr ARRL 4SQRP #801 - NAQCC #7625 - SKCC #10098 FISTS #17157 - OMISS #9886 LFSARC (Lawton/Fort Sill Amateur Radio Club) Michael T McEwen Lt Col, US Army, Ret Cellular Phone: 580 919-9205 Residence: 580 529-3412

Re: Really dumb crystal question
moshecontra
I think you mean the PSK-20, which SWL sold as a kit, single-frequency SSB trx for 20m PSK31. The SW40 was a CW-only 40m rig. I have embarked on a long-term project to try and coax the SW40 to transmit PSK31, using a simple low-frequency interface circuit between the PC and the radio. I got that interface working, but still have to see if the tx final can be modulated to output a clean enough signal, since it is designed to be class C.
Since most PSK31 activity on 20m is within a single 3 KHz range (roughly 14070 to 14073, many different QSOs can be worked simultaneously with the PSK20 with its fixed "carrier" frequency of 14070, a 3 KHz wide IF filter, and PSK31 software on a PC. I don't see how a crystal-controlled voice-SSB rig would be very useful, though, as there could only be one QSO at a time within the 3 KHz channel. Change the oscillator to a VXO, tweaking the crystal frequency over 10 or 20 KHz with a variable capacitor or varactor diode, and it might become useful.

Re: Really dumb crystal question
Bill Cromwell
Hi Michael,
toggle quoted messageShow quoted text
I have a Small Wonders Lab SW-40 PSK for 20 meters. It IS a SSB transceiver with an xtal oscillator where a VFO might be in other transceivers. I don't think those are available any more but you might find for the band you want and change the xtal for one that operates the radio on the frequency of your choice. Some single frequency radios have the IF filter on the operating frequency as well but this one has 9 mc xtals in the filters. You use a VXO circuit or a plain xtal oscillator with trimmer inside the radio. I hope this helps. 73, Bill KU8H

Re: Really dumb crystal question
Jon Wanzer <jon@...>
Greetings Doc, As for homebrew/kit I know of the Beach 40 which is DSB. I have seen it in 17, 20, 40, and 80 meter. I am actually building one myself right now and documenting the build on my website. I am also looking into the BitX 20 which is SSB and I have seen it in the same bands. I know the BitX can be bought as a kit, though I'm not sure where or how much. The Beach, I don't know if it has been kitted. I wouldn't call them "micro" but the Beach 40 I am building could most likely fit in a case about 1/5th the size of the case I am building or less which is 8" wide, 3" tall, and 6" deep. I could probably get it down to 2 x 3 x 6 if I used a vericap. The air-variable takes up almost as much room as the rest of the radio!

My Alex loop has been a real pleasure for in the shack and portable operations. One thing I suggest is a non-metallic little stand for setting up portable. PVC small pipe and a 3/4" short dowel rod is what I use. Be creative and light weight! 72, :........Walter Dufrain - K5EST........:

Re: Really dumb crystal question

Any K2 with a serial number above 4660 has all the Elecraft mods
installed.
toggle quoted messageShow quoted text
One with a serial number above 3000 has all mods except for the PLL temperarture stability (thermistor) mod and the K2 Keying waveshape mod. The keying waveshape mod kit is no longer available due to the unavailability of the PIN diode, but is not necessary in a QRP K2. If it has a serial number below 3000, ask if it has had *all* the A to B mods installed - many have. Any K2 can be upgraded, and the cost of all the upgrade kits is about $110 - add $54 if the firmware is not up to date. The latest firmware is MCU 2.04. To see the firmware level, hold any button in while powering on, it will be briefly displayed. 73, Don W3FPR
