perhaps the linked directions might be amended to include this
vital information, so the next person doesn't have to discover it
the long way.

I'm assuming you do not have a google account.? We later figured
out that even with the permissions set as open as possible you
need a google account to post.? That is one unfortunate issue with
the platform.? As always, if someone has a better way to do this I

Re: Farhan VU2ESE'sTwo Tone Generator
We are discussing the rf two tone generator. The emitter should show at least 500mv of RF.? I still suspect measurements. It is like this, the oscillations need the amplifying device to saturate for the oscillations to sustain. They wont do that at such low outputs. Can you check the voltages at the three leads of both the transistors?

The one I was referring too was the one on his site that was available from the above link and was for a RF system. I did not dig farther to see if he had an audio version.

Re: HEY NEW PERSON, yeah you, go check out bitxmap.com and mark your spot in the world
I think part of the problem may be in the provided instructions,
specifically this step:
??? click add to
map at the bottom of the box that pops up
...there is no "add to map", nor is there any box that "pops
up".??
what you *can* do, is look up an address and then click "show on
map" at which point a little (red) dot is shown on the map.???
Still no boxes popping up.

Re: Farhan VU2ESE'sTwo Tone Generator
Looking at the schematic of the output combiner, are you really using 150 ohm resistors for a 50 ohm system? Every similar output combiner I have ever build for a 50 ohm system has 50 ohm resistors.

Re: Farhan VU2ESE'sTwo Tone Generator
Are you sure your oscillascope is not on 10x vs 1x? It seems to be exactly 10 times down. Check some dc voltages with the scope and the bandwidth settings too.

Re: Farhan VU2ESE'sTwo Tone Generator
Hi Ashhar,
At the oscillator emitter the voltage is 72mV peak-to-peak.
At the amp collector it is about 9mV
Both with a 49.9 ohm load. Something is quite wrong now, the max output is only 5mV at the attenuator output.
Faulty transistors?

It seems that there may be room for some modification of the BITXMAP software. If it were coupled to a remote receiver or one of the beacon receiver systems it
might be possible to make BITXMAP more usable by showing if a BITXMAP location
has been active recently.? A cell phone app might be supplied that allows users
of BITXMAP to see who is active at any particular time.? A bit more exotic, but if
the site supported SMS (Short Message Service) it might be usable as a contact
scheduling system.? Lots of possibilities if you think about it.

Re: Farhan VU2ESE'sTwo Tone Generator
Elia, 40 mv is really low. Can you measure the rf voltage at oscillator emitter and collector of the amp?
I love seeing builds like this! Dave Richards, AA7EE, carries it to an art form (notice Han's BPF in the photo):
A visit to his site is just plain enjoyable to me.

Hi everyone,
I started building the two tone rf generator from Farhan's ?site to add to my test equipment. I have finished the first section (ie oscillator #1) and tested it to see how it functions. On his website Farhan mentions in the calibration procedure that one oscillator should give about 200mV p-p. I can only get about 40mV, anyone has any suggestions or thoughts as to why I am measuring such a low peak to peak voltage?
I have double checked the component values and am confident of their ratings so I am very confused at the moment...
Any thoughts and suggestions are highly appreciated.

I cannot get the map entry to work?? Perhaps somebody with better
skills can make my entry.? My location is in Winnipeg, at 555
Ellice Avenue.
