Re: BITX20] HEY NEW PERSON, yeah you, go check out bitxmap.com and mark your spot in the world
Well, if you give me a few days and contact me privately at djmalak2k6 at gmail. I can look at the api. I just want a way to see what they want so I can advise you of the best solution.
Hosting will be cheap, but I am not familiar with google. I learn fast. Chris? |

Re: DX and antenna
Simian
Here i use a small 2 element beam on 20,15,10m and verticals on the other bands, plus I sometimes use an end fed halfwave (EFHW) .? a dipole or EFHW certainty is a good antenna, if space is short bend the ends. My ubitx can qso 5000 km on ssb, conditions do change. Once I gave my call sign twice, and a op in Europe chastised me since he heard me easily the first time, and we doubled.? Erect whatever antenna will fit, a 20m dipole with bent ends can make qsos. A qrp EFHW for 20 or 40 meters can be home constructed, info on line. You might need help finding a source to make the ferrite balun in your country or region.? Curt wb8yyy? |

If an api exists, I would be happy to work on thisChris, Thanks for stepping up and offering to help.? I started looking at the API's available and they now all require a billing account to access.? While I am happy to keep renewing the domain I am not really in a position to tie my credit card to the map not fully understanding what kind of cost would add up.? The map data can be manually exported as a kml/kmz file but that is static.? I threw together the current map on a whim a few years ago thinking there might be interest and personally not knowing how to do anything else.? We might be at the point where starting over is the best approach ideally pulling in the existing data.? Whether that is of interest to you or not you will have to decide.? I've said it many times and I still mean it when I say I do not consider the map, data, or domain name mine I was just the first person to do anything with the idea and would happily hand it all over to someone that actually knows what they are doing with the only stipulation being no one profits from it. ? -- |

Re: Farhan VU2ESE'sTwo Tone Generator
Right, I did some DC measurements as follows:
Oscillator Transistor E-7.02V B-5.81V C-11.91V Amplifier Transistor E-2.94V B-3.61V C-11.84V Next I checked the scope probe and scope settings, Ashhar was spot on correct, the probe was set to x10 but the scope was expecting a x0.1 so when I changed the probe scale setting on the scope to x10 I got the correct 200mV output of the circuit :) I knew the probe was set to x10 but I did not know that the scope also had an input scale setting..... Well never too old to learn Thank you everyone for your help with this, as with most issues it is usually the simplest things that are mostly ignored? 73 Elia, M0ZHN |

¿ªÔÆÌåÓýin fact.. there's a step missing, as well. ?-- after being logged in to your google account and viewing the bitxmap page, you next click the [Edit] link immediately below where the link to the instructions is displayed.? Then, the entire screen redraws in a new (editing) interface, which then behaves as you describe in your instructions.

¿ªÔÆÌåÓý...should never assume.?? ;)
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.

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?

¿ªÔÆÌåÓýI 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.

I would think it depends on its purpose -- is it made for feeding a mixer or feeding a mic amp?
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. |

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. On Thu 1 Jul, 2021, 7:28 AM Terry VK5TM, <vk5tm@...> wrote: Bit hard to tell from the photo, but is the transformer wired correctly? |
