WARNING! If you have the F16 Blue Edition , please do not upload older software 1.00…1.25. If you do that, some functions of the receiver may be blocked, upload of a new SW using the COM-port may be needed. To avoid this, please use SW with numbers 2.xx and newer.

 

SPECTRUM ANALYZER AND FFBS

Q. I tried to find your famous spectrum-analyzer function in the menu, and I couldn’t find it. Why?

A. It is there. Here is some short manual about the Spectrum Analyzer.
Spectrum Analyzer is the technology developed exclusively by Dr.HD™ to enable the customers to enjoy some pro-grade functions, usually available in the professional meters with Spectrum Analyzer. It is a tool that gives a lot of fun to satellite enthusiasts, and quite useful, too.

For using the SPECTRUM ANALYZER please do as follows:

1. Press MENU on the remote control
2. Go to the Dish Setting menu. (Press pin “0000” if needed)
3. Go to “8. DiSEqC motor”
4. Use the green button

And you will see the Spectrum Analyzer.  Some hints:  With yellow columns, the level of signal is shown. When the column is blue-coloured, it means that this frequency is within the Transponder  List for the current satellite.  With the red colour, the current Transponder is shown. When the column is green colour, it means that the receiver tried to receive that frequency, and successfully locked to it (please press the yellow button to do the lock test!).

Using the keys at the bottom of the screen, you can choose the Horizontal/Vertical polarization, and 22kHz on/off for Low/High Band. If you press YELLOW button, then the receiver will try to LOCK the signal for the transponders, and with GREEN COLOUR will display the transponders that are LOCKED.

Using Spectrum Analyzer, you can change the LNB’s functions. By pressing the GREEN BUTTON you can select either Vertical, or Horizontal polarization of the LNB. The RED BUTTON selects either High Band, or Low Band, when using the Universal LNBFs.

The size of the columns correlates to the  signal level. Columns around zero indicate that signal is too low, signal/noise ratio is bad, and quality reception is not possible. Levels of 255 (maximum value) show that there is “too much” signal, and there is some chance that the tuner is over-loaded. Too high levels of 255 typically happen when additional high-gain amplifier is inserted, which wasn’t really needed. The signal is at its best when the level is somewhere between 200 and 250.

Another use of the spectrum analyzer is for testing your equipment and finding the weak points. When the signal is high at low frequencies and low at high frequencies – may mean that you are using extremely low-quality cheap RG-6 cable. You can even evaluate the quality of the cable or your DiSEqC switch, or your DiSEqC 1.2 positioner. In case, after connecting that cable/switch/positioned the signal drops significantly (especially at high frequencies) – it is better to avoid them.

And, of course, you will be able to tell one satellite from another, by a simple glance at Spectrum.

For better examining of some part of the spectrum – you can use the scaling/zoom function. For example, if all of your signal is between 200 and 250, and you want to see the exact details, you can opt to display the signal levels from 200 to 255, only. You can also “zoom in” some specific frequency band, and discover some transponders not in current database (yellow-coloured peaks). So you can add them to database and blind-search them, so you will get the excusive up-to date TP database.

 

Some versions of the SW, have the SAT ID function. When you already have good signal (spectrum is high!),  but you are not sure what the satellite you are receiving, you can call the SAT ID function by pressing the INFO BUTTON. The receiver tries to identify the satellite and will give you the result after some processing time. Please, note:

1. For each satellite, some unique TP shall be used (first in the list). For HotBird, it is the TP 10723 H with SR=29900. For Amos, the TP 11167 H with SR=12500, etc. Please avoid the typical TPs with SR=27500 and SR=22000
2. After pressing the INFO BUTTON, the receiver starts checking all the TPs, one-by-one
3. When TP is locked (there is digital transmission on that frequency), the checking stops. You have option to re-start, continue or commit a full-search of the satellite

We aware that this function can not be 100% accurate, until we designated unique TPs for all the satellites, etc. But it is fun to play with for a start, and when our customer base is good enough in all the major countries in the world, we will come back to it and we will make world-wide database, good for identification of all the satellites.

 

Q. Will there be Spectrum Analyzer for the Terrestrial (DVB-T)?

A. Yes, we can do it. (It is much less use, anyway. But if you want to play with it … okay.) But we will publish it only after we have done some additional protection. Some competing companies are trying to copy all our achievements, and there were some stealing issues with the Satellite Spectrum Analyzer, so we need to take precautions, regarding the technology protection and IP issues as well. We have much more interesting ready for our customers, and we publish when we have more protection, either way.

 

Q. How to use the FFBS (Fully Functional Beep-Search) function?

A. Please, follow these steps:

1. Press MENU on the remote control
2. Go to the Channel Search menu. (Press pin “0000” if needed)
3. Select the right transponder/frequency
4. While on the “5. Network Search” line use the green button

You will hear a beeping sound, which corresponds to the strength of the signal received. We tried to make it more informative, so, unlike other receivers, both volume and pitch of the sound is changed, for better accuracy and functionality. So, you can be few rooms away from your TV, and still able to fine-tune your dish. You can even call from your home phone to your mobile, go to the roof and tune your dish, easy and convenient.

 

SOFTWARE

Q. I have uploaded the new software and something happened, like: 1) sound disappeared on some channels, 2) some channels do not show, 3) receiver doesn’t memorize the Terrestrial channels, 4) some channels are lost, 5) some function not working, etc, etc.

A. When making a new SW, we use a new memory map for some new releases. It means that receiver becomes “uncompatible” with the data in the memory, and it is better to do full factory reset after each software change. So if some stupid bugs happen, please do full reset. It won’t hurt.

 

Q. But I don’t like that! I have to re-scan the channels after software upgrade.

A. We know it is not something to be proud of. It is just matter of fact, and it is because of memory mapping  we used to, so we have to warn the customer about this. And within next SW releases, we try to make unified database, consistent from release to release. At the time being, there is a workaround. We advice to use the function of storing the current databases to USB. Just go to the “File manager” menu – and store all the channels, settings, etc to USB. After upgrading the SW, spend few seconds for re-installing the channels, etc. (Anyway, 80% of the customers do not change the SW very often – no need, other 20% of enthusiasts will have to use workaround. Anyway, we intend to fix this issue).

 

Q. I am confused. How come older SW had the numbers of 1.xx and newer releases are 0.xx, also there are versions 2.xx. Please, explain.

A. Correct. Our older SW numbered 1.00-1.25 is “single” version. It means that it allows to process only one channel at any given time. Later, we released the beta-versions of software (0.xx), which allows processing of two-three channels,  at the same time, giving more possibility of recording one-two channels + watching channel, etc. Also, we were beta-testing some new nice functions including external temperature sensor, etc. First releases of the 0.xx were not very stable, so we didn’t want to make them public and marked them with “0”. Now the new core is getting more mature and stable each week, so new SW got numbers 2.xx and we encourage to use of the SW from 2.01 and up.

Also, read the warning above: please, do NOT use software older than 1.25 for the F16 Blue Edition.

 

Q. I was told that the recordings made with the Dr.HD™ F16 can be opened on my PC with the free GOMplayer, without any conversion. After installing the GOM player, it says “Can not play the file.”

A. Yes, you can watch the recordings made with the Dr.HD™ F16 on any PC with the free GOM player, without any need for conversion. We (and our customers) tried it many times, and it works. Please go to the  http://www.gomlab.com/eng/GMP_download.html page, and download the latest version (free!). Then, read the manual at http://www.gomlab.com/eng/GMP_Howtouse.html. There, you will find out how to download the missing codec, etc.

 

 

BUYING THE RECEIVER. DISTRIBUTION

Q. I am in Germany. Where can I buy the F16?

A. Currently we do not have distributor in Germany (at the time of writing). Recently, we have supplied some samples of F16 Blue Edition to some companies in Germany, and we hope to finalize the deal soon.

 

Q. I don’t want to wait, where can I buy it now. I live in Germany.

A. Please take a look at our “Where to buy” page at our web-site (http://www.dr-hd.com) , and locate a dealer nearest to you. Some resellers even use the E-bay (http://www.ebay.de/).

 

Q. There is still no dealer in our country. I want to buy within my country, as I will get better support, etc.

A. We understand. Let’s explain. We are young as a company (our team is together since 2007), but most of our stuff are in this business for a long time, with big experience. Therefore, we remember what happens when some new companies start to offer their new ‘revolutionary’ box to distributors in many countries of Europe, etc. The purchasing managers start thinking “Oh, just one more box from one more potential supplier.” Quite natural, isn’t it? We came here to show that we are not “just one more company with just one more box”. We have released not just A new box, but we released THE new generation set-top box. We haven’t shown 5%  of what we can do, yet. We know that. Also, we know that other companies, big and small, will try to copy us. (And they are doing it now.) And we know the clients will come to us. We don’t believe in the model of “active sales” (actually, “push-sales”), like many Korean companies are using. We are working hard on new features and unique functions, making the Dr.HD F16 the first receiver in the world of this class. New features are attracting active and sharp-minded clients, like you. These (potential) clients are pushing the importers of the satellite/terrestrial receivers in specific countries. They contact us and we start doing business. So, if you are interested to have a local dealer, why not to ask your nearest dealer/distributor/importer.

 

DIFFERENT VERSIONS, BLUE EDITION, ETC

Q. I have bought the F16 Blue Edition, how many card-readers shall be there?

A. By default, there is only one card-reader (bottom slot). The second card-reader is optional and can be installed later, if needed. There is a check-box on the receiver’s giftbox, when the second card-reader is inside, it shall be marked.

 

Q. I have read that there is F16 v.2 receiver in production. Can I buy it?

A. It is just some rumours on the Internet. Right now (as of December 2009), we do not have any F16 v2 in production. We have the first edition of F16 (black-and-white giftbox, produced from late 2008 until August 2009) and the newest “F16 Blue Edition” (available from September-October 2009). You can easily tell one from another by looking at the Dr.HD logo on the giftbox. Right now (end of 2009), we have only Doctor HD F16 Blue Edition in production.

 

Q. What is the difference between the first release of the F16 and F16 Blue Edition.

A. There are few new features in the Blue Edition, including:

• Now it can work with our External Temperature Sensor (no extra cables needed, current RG-6 is used), so you can see the current temperature either on the TV screen, or on front panel of the receiver. You can see the front panel picture here: Dr.HD_F16 new panel temperature meter.jpg.  (Optional temperature sensor needed. It is currently under production, will hit the shops soon.)
• Blue Edition can have two card-readers (optional; by default only one is installed, second one can be added and installed without any special tools)
• New remote control is used, with IR-beam’s wider angle, so there is no need to aim the remote to the receiver
• Now buttons of the remote controller are fluorescent and glow in the dark
• Other changes of the hardware applied

IMPORTANT!!! We respect our customers, so our goal is to make all our modifications of the receivers compatible. It means that  when adding new functions, whenever possible we try to make these functions available for all the current customers that had previously bought earlier releases. Our goal is to guarantee compatibility of newest software and older hardware releases.

 

Q. How can I tell the F16 Blue Edition from the F16 First Edition?

A. By looking at the giftbox of the receiver.

The logo for the Dr.HD F16 First Edition is here:

The logo of the Dr. HD Blue Edition is here:

 

 

BLIND SCAN, DXing

 

Q. Blind-scan function works wrong. It scans the same satellite FOUR times.

A. Please, read the Internet about the LNB works. http://en.wikipedia.org/wiki/Low-noise_block_converter There are, actually, four bands the LNBs must scan: V low, H low, V high, H high. So, it only looks as “four-times scanning of the same freqs”, however it means the correct operation.

 

Q. Can the blind scan find the HD channels???

A. Yes, unlike many competitors, our blind-scan function works with HD channels, too.

 

Q. Can we receive extremely low-SR SCPC channels?

A. Yes! Our receiver is already recognized in the DX community because of that, and because of other functions.

 

TEMPERATURE SENSOR

Q. How to use the External Temperature Sensor function.

A. Just connect the external Temperature Sensor (supplied by our company) into any convenient place of your RG-6 satellite cable (outside your house, of course), and your receiver will detect that sensor, and you will get the external temperature on your TV screen (by pressing the info button), or in standby. So take a look to the F16 front panel before going out, and you will be always dressed according to weather outside.

 

 

MISC

Q. I still don’t see reply to my question.

A. Please, go to the Forum at our site, where you can ask the questions, and we will post the replies here. Or send question by E-mail.

 

Q: Is the Thermo Sensor included in the package?

A: No, currently it is NOT included with the set-top box. It is offered as an option and sold separately. In the future, there may be

some De-Luxe package with ThermoSensor included. Maybe in Dr.HD F16v.3.

Any further questions ,please feel free to contact us.
