I've been trying to find a suitable case here in the UK. I can ship from the Container Store store in the US but I'd be absolutely crazy to do it. The case would cost me $10.34 (purely because i'm in

Chuck; I think that you should write up this keyer mod and submit it to ARRL for possible publication in QST! This 49er/VFO, I would guess, has been a popular build project, and guys like me, would

Thanks a lot, Mark. After work I will scope Q6 and probably swap for a 2N3904 running with 12V tops. I will let you know results. Bob

I think you meant the collector of Q6, not "D6" Marc(?)... Cheers, Jim, ab1br

I have quite successfully used these encoders from China and by carefully dismantling have been able to remove a tiny ball bearing to end up with a smoothly turning frequency controller for my SDR (no

Hi Chuck: No need to "hide" Glen's work. Indeed, I met him two years ago at the Four Days in May conference that takes place each year in Dayton just before the hamfest. He's an interesting guy. BTW,

After I built this fun project, I thought it would be interesting to add a software keyer. I looked around, and found some simple iambic keyer code in that other Arduino for Ham Radio book (published

Bob: I also had the same problem with both of my 49ers. The first one was a blown driver transistor, Q6. It would work for a few minutes and then..... no output. I placed my finger on the transistor

This was also on the site and looked closer to the size I want:

Been reading about the VFO output level, so I took my scope to it. I set it to its lowest level of about 400mv and the rf OUTPUTvoltage level was very low. The heat sink remained cool. Putting it back

Thank you, Jim. Based on your clue, I lowered the signal on pin 6 down to 250 mV PEP, but still have my click. There is still a fly in the ointment. I hate flies. Bob

HI Jim: I wish I could be of more help, but like I said, in lack the knowledge. I will forward this to him. He just started his semester so I know he's busy, plus we're working on a new project, too.

Hi Bob, I've mentioned that the data sheet for the NE612 specifies 200mVpp minimum to 300mVpp maximum for the NE612/602 L.O. input (pin 6). Using the buffered output on the DDS VFO, I was only able to

I programmed the ATTiny85 first with the Blink example and it worked blinking 6 seconds on and 6 off. Then I tried CapSenseKeyer with a board from a friend and no joy. So, I studied the code and

I will test voltages on both sides of L3. After work I will take the rig apart. It would be nice to have a few test point values from a working rig to help isolate the culprit. Bob

OK. I just wanted to be sure you weren't using the code for an Arduino. Let me review things tonight...probably will get back tomorrow. Jack, W8TEE To: SoftwareControlledHamRadio@... Sent:

There's only one file and it appears to be for both. Bob

Are the voltages on the final reasonable? Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Thursday, August 18, 2016 4:04 PM Subject: Re: [SoftwareControlledHamRadio] Forty-9er

OK...found it. Are you using the code with the Digispark or the "raw" ATTiny85? Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Thursday, August 18, 2016 4:02 PM Subject: Re:

In case that was the cause, I replaced the D882 with a BD139 from W8DIZ. Same problem. Bob
