Thank you Bob, I will check the LED circuit again. 73. Griff NE3I Robert Alan Griffiths

Thanks Dave, I will check it out. Griff NE3I Robert Alan Griffiths

Robert, I also just built the 4S tuner and had similar problems to what you described. I found that the wires from switch SW1 were touching the switch body (the metallic part) thus shorting the XCVR

Sounds like bad solder joint around led circuit as seems tuner part is working and noise will not be as loud in tune mode as it is with tuner out.

I have built several tuners using a led as a indicator. Works ok with my 1/2 watt rigs. 72 George/W2BPI

Opened up 4SQRP lastest Kit. "Murania AM Broadcast Band Receiver". Wow this is a great beginners kit. If they are old enough to read instructions, and you help them a little on soldering they will

I recently built the 4S Tuner. Neither light illuminates. In the tuning mode, adjusting the switch and capacitor positions varies the noise level however, in no position is the noise level as loud as

In the tune mode, the power to drive the SWR/Power LEDs is provided by the transmitter. I understand that the tuner is good to 10W, but what is the minimum power that will adequately drive the

No matter what soldering set you use I have found that one should order two (especially if they are inexpensive. Mine were about $40 each)! I ordered two in error but have found that having one set

Thanks everyone for the replies and ideas! kd0wkv

Rob, There are many choices for a good solder station. I looked at several and decided to buy the Solomon SR-976 from Circuit Specialists. It is variable temp and about $45 if I remember correctly. I

Rob, I recently purchased one of those YiHua 936 (actually a Hakko clone and will take their tips). My favorite soldering iron power supply shot craps and wanted a backup. I think it's pretty good

Rob, One of your questions was the diameter of the solder.... my preference is to start with is .015 for the tight work and maybe .031 for the larger components, when you get to cables and wires you

Here is my recommendation. This one has digital display and holds your solder roll! I have had great results with this one. X-Tronic - Model 3020-XTS LED Display Soldering Station | XTronicUSA

I've used most of the available soldering irons, and have kept the 898D+ 2 in 1, because it is easy to set the temp, and easy to swap tips. and the tips seem to last a lot longer than others. Doesn't

I borrowed a friends's Aoyue 469 and liked it so well I bought my own. $30 from Amazon and other places, up to 80 watts, uses Hakko type types. I prefer the 1.2mm chisel for kit building. Just

What a great response to this question!! This is a prime example of why 4State folks are the best and why our group continues to grow, even in times of poor propagation!!! cu es 72 Bart W0IIT 4Sqrp

I am a big fan of the Weller wesd51 for through-hole. It, or a similar Hakko are the best options for a beginner.

I have been using this soldering iron for 2 years and have been extremely pleased with it. YiHua 936 Rework Soldering Station SMD DesolderingSolder Iron w/ Stand 110V US

Hello :) Good work soldering modern electronics , works best using quality tools and solder ! I use a HAKKO FX-88D Digital Soldering Station ! The Tip is a 1.6mm HAKT18D16P T18-D16 Stay away from lead
