William, Don't feel lost. afterall thase things happen.as you took out the ADE-1, once, do it again?while it is out, using datasheet for pin id, test cross insulation bteween winding 1-6 ?to other

The eeprom has limited write cycles. It might make sense to write less frequently. Possibly when you switch betweeb vfos or toggle the rit. - f

yes i can use that as the band plans here in Thailand has a max 7.2MHz. Hope to hear you all some nights. Nemo.

On 40m, it moves through 3000 khz. ?Call it MST3000? https://en.wikipedia.org/wiki/Mystery_Science_Theater_3000 ( https://en.wikipedia.org/wiki/Mystery_Science_Theater_3000 )

Haven't I seen "Stutter Tune" and "Flutter Tune" on the site? What about "End-Stop Tuning" since that sorta describes how it works. Jack, W8TEE To: [email protected] Sent: Thursday, April 27, 2017

The ability to use a simple linear volume control as tune control for a radio... If you think about it's like a moving slot under a calibrated ribbon that allows you to see the whole dimension

Pavel, Culturally, I would stay away from "pot" and "auto-tune". What would you consider its key abstraction? Rate tune, proportionality? PTune.lib, EZtune.lib. Good luck. Sounds useful. Bob

Hi. I'm working in something named arcs-bitx (a mix of arduino-arcs + bitx) and I like to separate the ingenious tune mechanism of the bitx (analog lineal pot tune) on a own lib. I'm not english

Steve, It's hard to understand the issue without knowing what addtional code you are actually using, or what exactly you 'comment out', but my guess is that any of your additional mods use pin A2 for

Can we check for reverse mounting - as the item is expected to be mounted on solder side. please let us check for any improper orientation. all the best sarma vu3zmv lee.hemmingsen@...>

I checked all the traces, an I see no bridges. I removed the ADE-1 and shorted pin1 to 6 using a wire. Now no longer does R15 get hot. So that eliminates anything in that path. So that leads me

Check for a solder bridge or a tiny copper trace that remained when the pcb was etched. You can use a magnifier or a meter to check it. What you might also do is to run a knife between the tracks to

I'm modded out with s meter forward and reverse power measuring. I have 1 button and 1 switch. tried unhooking the switch all together but still happens may have to try shielded wires for the

Steve, Just to understand your situation better, what is exactly your setup? Standard unmodified BITX40 board with raduino_v1.07 (or 1.08) with the standard PTT switch? No other pushbuttons wired up

OK, As Steve has posted, did you get any IF (12mHZ) response ? Another quick and dirty test. If you have access to a general coverage receiver use the draped wire (near the first mixer) this time

Let us hear a recording clip of the hiss. Might give a clue.

Thanks Allard ! Will load it upto the board tonight 73 ON2AAV

What if you 12MHz sweep the input to the IF near the crystal filter near C61 ? Use a small metallic screwdriver in your hand and start from the audio amp and work backwards toward the RX front end -

The only thing i receive is static. ive set el cheapo sig gen to sweep 4.5mhz to 5.5mhz and 11mhz to 13 mhz and 6.5mhz to 7.5mhz (got those ranges from the source code from the raduino src and xtal
