Here is some additional info. The delay is experienced even with the Forty 9er not connected to the DDS. I put both of my Forty 9er boards on a test stand with nothing but an antenna, headphones and

Dennis: My units had never exhibited this behavior, so I fired mine up and, after FIVE minutes...nothing. Then I had one of those flat-forehead moments where you slam the heel of your hand into your

ALL, I have noticed an almost 2 minute delay from the time power is applied to the Forty 9er until receiver actually operates. I get an audio hiss as soon as power is applied, but the actual receiver

Hi Norbert. Since I was using the RF Probe on my VTVM to get what I *incorrectly* thought was the peak-to-peak value, I simply used it again. However, this time, I used the formula to calculate RMS to

You can measure the resistance across R1 before it's part of the circuit and adjust it for max reading. Then you know that it's in the circuit with the highest resistance possible. 73,Jack, W8TEE To:

Hi! Interesting information Aaron, I would not expect the d882 to be tied to the RX side of the circuit. Puzzling indeed, I'll take a closer look at mine tonight. How did you reset the peak to peak

I'm sure Farrukh and Dennis can give a more precise answer, but I'm pretty sure it's because you put the white smoke back in. Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Thursday,

Gents, This is indeed a puzzler.. and there's something else I want to bring up on the odd chance that somehow it's related. As you know, I blew out my original D882 output transistor. While I was

In the interim, I've ordered another forty-9er kit from a different supplier. I'm going to check each component and compare the two boards. I'll build the new one and try and still figure out what's

Hi Steve. My understanding is that the 2SK30A is installed as a TX Mute transistor. Aaron - N2HTL On Mon, Apr 25, 2016 at 5:26 AM, ns3l@... [SoftwareControlledHamRadio]

I'm still thinking some component is bad or perhaps a break somewhere in the board. There are just too many others who have the rig working for it not to work adequately. With your external amp, probe

Aaron, While my 49er has some transmitter problems, the receiver audio level is fine. I am moderately hard of hearing, so a low audio condition would effect me even more than a person with normal

Interesting....I thought it was my head cold that caused the low audio output. I built an audio signal tracer a while ago that uses a 386 and that output is great....going back to the bench to look at

Aaron, If I'm not mistaken isn't the 2SK30A "Q1" the preamp in the audio chain? When I looked over the circuit diagram then and looked up the 2SK30A, it's listed as a pre-amp.. Just thumbing around at

Evening all. I wanted to toss this out in order to get some feedback on the low audio/hiss issue from the 49-er. I put together a basic amplifier using a spare LM-386 chip. Once the amp was finished,

Hi, With the plethora of Ebay kit sources and problems with questionable parts quality from some, can anyone recommend a kit provider that you like? 73 Dave KF5OCP

Hi Frank, Yes I got the parts and used them.. Thanks very much.. As far as everything else I'm going to change parts one by one if needed.. Steve NS3L..

Steve: I replaced most of the Forty-9er components with my own parts. The parts in the kit just didn't appear to be of high quality. With exception of the D882, only a few of the supplied parts were

Steve, I just tried four different LM386 chips from a bunch I purchased from Tayda Electronics. Every one of them exhibited the same low audio qualities and excessive hiss coming from either
