How do I power the 49er ?
|
Aaron Heverin
Hello Norbert. I'm glad you found the solution. Was just about to respond when I read your latest post. Glad you got it resolved.? I was wondering if you could do me a small favor. Once you power up the 49-er and get a chance to test it out, would you please report your findings on the quality of the signals coming from the audio output of the 49-er? I'm chasing down an issue with what seems to be excessive hiss - not band noise - coming from mine and since I've never assembled a 49-er before, I'm not sure how it's supposed to sound. Having another example to compare mine to would be a great help in determining if anything isn't right here. Many thanks... and best 73s. Aaron - N2HTL On Sat, Apr 9, 2016 at 9:28 PM, wp3dx@...

Aaron, What does the audio sound like with the antenna disconnected?? Are you hearing 40 meter band noise, or are you hearing audio hiss from within the 49er circuitry. I have one working and it does not have hiss when the antenna is disconnected.? Also, what are using for the 12 volt power supply?

I connect the 12V to J1; + to pins 1 or 2 and - to pins 3 or 4. Jack, W8TEE From: "wp3dx@... [SoftwareControlledHamRadio]" To: SoftwareControlledHamRadio@... Sent: Saturday, April 9, 2016 6:31 PM Subject: [SoftwareControlledHamRadio] How do I power the 49er ?

Hi! Quick question,?I see pins 2 and 4 in the diagram to power the VFO board and I already tried it when calibrating the mini360 ?5V output.? My question is how do I power the 49er ? Does it feed from the VFO board ?? Thanks in advance. Norbert |

Hi Dave. Just disconnected the antenna and there's a lot of hiss on the output. Of course, the band is flooded with signals tonight due to the SKCC Weekend Sprint going on so it's much busier than it was last night. But regardless, with just a pair of earbuds on, it's very hissy. On very weak signals, the hiss makes it very hard to copy any weak signals.

What are you using to power the 49er with, battery, wall wart, 12 volt supply??? On Saturday, April 9, 2016 9:15 PM, "Aaron Heverin aaronhev@... [SoftwareControlledHamRadio]" <SoftwareControlledHamRadio@...> wrote:

I have a Jetstream 30A power supply with adjustable output voltage. I run it at 13.8V for my 100W rig, but 12V for my Forty-9er. Wall warts can be very noisy and so can some cheap 12V supplies. If you have a scope, look at the output. Jack, W8TEE From: "dfine100@... [SoftwareControlledHamRadio]" To: "SoftwareControlledHamRadio@..."

Sorry... forgot to answer that question. I'm using a 12v, 8aH battery. It's the same one I use when I take my other rigs portable. Aaron - N2HTL On Sat, Apr 9, 2016 at 10:32 PM, Jack Purdum jjpurdum@... [SoftwareControlledHamRadio] <SoftwareControlledHamRadio@...> wrote:

Aaron,? I am using a 12 volt gel cell battery to power my 49er and I'm using Yamaha CM-500 headphones.? I don't know if the earbuds would make a difference or not, but as Jack just said, wall warts are generally junk and plagued with noise and are not acceptable for use on the 49er. Also, regarding the rotary encoder, I originally tried to use one of the encoders with the resistors on the circuit board.? It was one that came with one of the Arduino starter kits.? It did not work.? I don't know if it was a bad encoder (suspect it was), or if it was incompatible in some way.? I had some that were stand alones (not on a PCB) without the resistors that I had purchased from Adafruit, they worked fine. Dave, W0DF On Saturday, April 9, 2016 9:32 PM, "Jack Purdum jjpurdum@...

Thanks, Dave. Well... that's exactly what I'm using - a 12 volt gel cell. Heavy bugger but it's working great. The radio itself is working perfectly. The rotary encoder is tuning as it should. 40m is loaded with signals tonight. In fact, I'm making some contacts during the SKCC Weekend Sprint with the radio right now. I'm just trying to get to the bottom of the the excessive hiss coming from the audio output. Unfortunately, I don't have another LM386 chip on hand to see if perhaps the chip is weak in some way.?

My apologies to the group. It appears this thread has be hijacked to continue the discussion about the hiss issue I'm having with my 49-er. I have some additional information but I'll put it out on the thread I started regarding the issue - ?"40m QRP Transceiver Success." Many thanks... and apologies again.
