Right Arv ... Software is the way to go. Otherwise someone is being amazed by flashing lights and bird whistles. This is just one opinion, however. Bob — KK5R

Everything is relative. One's S-meter reading depends on the receiver AND the antenna. One too many variables. A Volume Unit reading is based on voltage across a standard resister value. The VU

Agree. Jack, W8TEE

Bob and Jack Seems that if you are using that circuit and an ADC input in place of an analog meter, you could use software to convert the ADC readings into VU meter, S-meter, or anything else. Might

My bad, it should have read: Again, I'm not an EE type, but if the metering is done off the volume control, is it really an? S meter or a VU meter?? Jack, W8TEE

The only "pop and smoke" experience I ever had was when I bought a Swan 350 at a hamfest that was a "Sure, it's working!" radio so when I plugged it in at home, it sounded like a shotgun shell going

Dave, I would agree that there are very few times that the combination of pop and smoke did not indicate something failed.? The only time I can think of that it was not a part failure was when a

Hi Evan, The comment was not directed at you but as information for the poster of the statement. I don't think that I can a recall a single instance where a pop and smoke left my equipment working. --

The signal off the volume control can be used as a signal source for either S-meter purposes OR a way to control an AGC circuit by causing attenuation for signals above a pre-set level. However, I

Considering that the radio's boards are pretested and aligned, causing smoke and pops would have to be an accident or intentional. I got my new V6 yesterday at the Post Office (DHL sent the radio from

When playing my new V6 on a local AM broadcast station and listening to the same station on my main radio, there is a way to know when the two signals are on the same frequency because you can hear

Again, I'm not an EE type, but if the metering is done off the volume control, is it really an SWR meter or a VU meter?? Jack, W8TEE

This again is offered to show an S-meter circuit borrowed from the transceiver circuit being sold from Indonesia. It is apparently attachable to the volume control and since it's in the receive

If Ashhar Farhan can calibrate the UBITX by the PC via web, what about a web app to decode SSTV? It can be done with laptop and easypal for example listening to the hand held, but it will be great a

Yes. Could be anywhere in the antenna system with a DC path to the rig.

Re, there may be things to dig around here in manager cdt

I think a 47kohm resistor from antenna to ground at antenna intake would solve it. Cheers, Jonas

Vic, I assume you are matching the hetrodyne of the uBitx BFO plus the WWV carrier against the audio tone from an AM radio also tuned to WWV. The tones from WWV flip between 500hz and 600hz each

Hello, I don’t know if anyone has ever put an oscilloscope on the BF part of the audio amplifier. Example connect to hp output with sufficient level. I notice that the calibragre gives a pure signal

AmatuerRadioKits sells an AGC that, per instructions, connects to the receiver input first IF at R10.? It does appear to work, though I have not done extensive testing. I am only offering up this
