Hi, My ATS-3A exhibits high current draw on TX on 20M only. About 780 mA at 9 Volts. The current slowly drifts down if I continue to key down. Down about 20 mA if I key down for about 5 seconds. The current draw on the other 3 bands is the expected ~500 mA. The receive current on all bands is a reasonable ~28 mA. The power output on 20M is 4.5 Watts. The power output slowly drifts down on 20M, following the current. What would be the first things to check? I re-wound a torroid on the 20M module a few years back when I discovered that it had the wrong number of turns. 73 Mike N9OHW

Would anybody with kit building or SMD electronics experience consider building my Soda Pop II kit for me in exchange for payment? I have zero surface-mount soldering experience and as much as I'd love to use this kit as a learning opportunity, I also really want it to work. I've been really itching to get a small rig on the high bands and I don't want to mess it up. I have the kit in-hand. I've been staring at it for a few weeks but I'm too scared to start building it. Who knows if Steve will have them available again in the future? The stakes are too high. (I'll se myself out.) I'd be happy to pay someone a reasonable price to assemble it for me -- it'd be even better if I could find someone around the Bay Area in Northern California. Thanks & 72, Justin / KN6JDF

I have all the parts (labelled and separated by source such as Mouser, DigiKey etc) to build this 30-40w HF kit. Designed by Jim Veatch of HobbyPCB details are at https://sites.google.com/site/dsp610constuction The original design is for a 6/10m rig and that is what I have the parts for. Cornell University have expanded this via a few parts substitutions to services 12/15/17/20. https://landau.geo.cornell.edu/dsp-620.html Both approaches require a case/front panel to be sorted out (I.e. one is not included). Package includes all the 6/10m PCBs and parts. This is not really a beginner kit but should be achievable for anyone with a small kit or two under your belt. $65 for the package and $18 USPS flat rate box shipping. Contact me at w6png@... Paul

Gang, QRPBuilder is announcing two new paddles. They are an iambic and single lever design similar to our other paddles, but are attached to your project by neodymium magnets, and can be moved from radio to radio, or removed for storage or transportation. https://qrpbuilder.com/magnetic-iambic-paddle https://qrpbuilder.com/magnetic-single-lever-paddle 73, Ken – wa4mnt

Anybody know what size plug it takes? thanks

I built the Soda-Pop II HB version a couple months ago and am posting here to say I’m having a ball with it. The high bands have been pretty slow in my area but I’ve still managed to pick off quite a few POTA stations with it from the home QTH. It took me two attempts/kits to succeed. Only a few years ago, I was able to hand-solder Si5351 chips, but I have now discovered, to my chagrin, that my eyes aren’t up to it anymore. This was my first go with solder paste and hot air; what fun! Very satisfying. I’ve gone through almost an entire roll of filament while trying to perfect a 3d-printed enclosure. Once I’m happy with the design, I’d be delighted to share it if anyone is interested. Hope everyone else on the reflector is having a good summer. —NCOQ Tim

Hi all, I'm finishing up my SODA POP high band and I have some issues. My main issue is that the solder paste and heat gun didn't turn out as well as I expected. I'm not surprised since it was my first venture with solder paste. I have lots of soldering repair to do and then some troubleshooting. I realize that I don't understand exactly how the SODA POP II works. I have looked for a complete explanation but have yet to find one. Perhaps someone can help if I list my questions. I have attached the schematics with the goal of tracing the RX and TX paths. For example a 21.060 signal enters at the BNC for RX. It gets some filtering and perhaps some amplification. It then needs to go to a mixer to be mixed with the LO to produce the 4.9152 IF. Where is the mixer? How does the LO of 10 MHz get changed to the IF when mixed with 21.060? How does the LO go from 10MHz to 16.145 or perhaps 25.9752 MHz so that the difference is the IF? Where does this happen? The IF then goes through the filters X1-X4 and gets to pin 3 of the U1a (TL072)....correct?? How does the encoder alter the IF when in CAL mode to peak it's passage through X1-X4? Where is the BFO produced? Is it at Q9 with the CT3 adjustments? How can I test if my BFO is working? Does the BFO go into U1b at pin 5?? Where does the transmit enter the schematic? My initial problem was no receive although I have a nice sidetone on transmit. The voltage at R22 was always above 500 mv (from 550 to 650 mv on multiple measurements). Why would it be high and is that the cause of no RX due to muting? There are multiple abbreviations I do not understand. SCL, SDA, +AV, TXEN, On ATMega RST, Vdd, Vaa I'm assuming that all the areas marked mute are areas that are grounded when the 2N7002 gets a voltage at its gate above a certain voltage. I am guilty of not fully understanding how these amazing rigs work. I really enjoy my KD1JV tribanders and my ATS3B. When I am done with my solder repairs I will certainly need to understand how the SODA POP II high band works in order to troubleshoot. Thanks for any help. 73/72 Peter/AA2VG

is there a more elaborate manual for the ld-5? i have the manual but would like more information. tnx Don w8ptb

What bands will the new model cover? Is there one for 80/40/30/20? 73 John N4HNO

my ld-5 gets 8w on ssb and 2 w on cw. I am a ssb guy so it is not a problem but curious why the difference. also it appears like the filter selection works for rx and tx both. iis this true? tnx Don w8ptb

I’m debugging a newly completed Sodapop HBII. Initial calibration/alignment went fine, however, I’m starting to chase my tail with what I feel is very weak audio output. I do not believe it is a receiver problem, because the sidetone audio is also very low. When I crank the volume pot all the way up, the sidetone volume is “just about right, but could be louder.” I haven’t touched the sidetone level adjustment pot; Steven indicates in the build manual that will likely need to be turned down, so for now I’ve left it alone. When I hook up a RF noise bridge, and turn the rig volume all the way up, I can hear the noise, but it’s not very loud. I tried injecting a -73dbm carrier signal on 21.060.600, and I can’t hear it. When I increase the signal level to -57dbm, it becomes audible, almost dead-on 600hz tone. Voltage at R22, on the AGC circuit, is 550mV with nothing on the antenna jack to the rig. It’s 1.2V with the RF noise bridge hooked up and the volume pot turned all the way up. I’ve tried a couple different headphones and they sound the same. If I were to probe the audio input to U3, the LM386, what sort of levels should I see on the ‘scope? Should I try pulling Q12 to temporarily disable the AGC circuit and see what happens? I doubt the AGC circuit is the problem because my reading of the schematic says sidetone shouldn’t be affected. I have extra LM386 to try but I’ve never seen one “almost” work; either they do or they don’t. Thanks for any input. —Tim NC0Q

Thanks to the group. I finally have received an ATS3a and an ATS3b to re-enjoy my misspent radio younger days. Now I am looking for a QBSA, the Steve Weber QRP Bench Station Accessory that allows one to use an ATS series radio as a bench rig. Any out there just gathering dust? Mine was gathering a little dust but I cleaned it before selling…. Ha! Please contact me at Djwilcox01 at gmail. Thanks so much. I have been a ham (legally) since 1960 but had fun with part 15 transistor transceivers in the neighborhood before that and am just wanting to play with a few radios I had in the past but regrettably sold. Life is getting shorter and things like this bring much joy to an old man. Be the REASON someone smiles today. Dave K8WPE

This is the KD1JV/KI6DS keyer kit from Pacific Antenna / QRPKits.com This is the initial build. The board is an early model where the holes weren’t quite lined up for the input jack. Behavior: No Side Tone (NST) jumper in place, operate paddle and connected device CPO or FT-818 produce side tone as expected. Press the function button and either paddle to recall a message. The stored message is correctly played over the keyer kit piezo. Even though the NST jumper is in place. However, the connected device does *not* correctly get/replay the stored message. For example, message stored, confirmed, and heard during playback is "TU EE” What is heard on the connected device is “T E EE” The connected device is not getting all of the keyed elements. Here’s my setup: Note, C5 is installed on the board. Connected to regulated Power Supply, 9.6V. Also tried with 9V battery. Stereo M-M cable connecting keyer and device. Key out jack is stereo jack. Connecting only to tip and shield. Piezo is 35mm disc. Piezo ground and key out jack shield both connected to Ground output pin. Piezo on ST output Output jack tip on KEY output. Troubleshooting: I removed the IC and cleaned the pins. No change. I replaced the 2N7000 at Q1 since it is shown as the keying transistor. No change. Build manual: https://www.qrpkits.com/files/SKC20170421.pdf So, big question is anyone have an idea why I’m not getting all of the elements on message play back? Secondary question, should the keyer produce side tone for the played message when NST is enabled? 72/73 de Bryan, k0emt
