You will find the Jupiter firmware at: https://www.tentec.com/?p=1332 <https://www.tentec.com/?p=1332> Be sure you use the correct version for your radio. I use a RS-232 to USB converter from R T
You can measure the driver bias at the Emitter of Q5, or at pin #2 of U1a, or at the junction of L1 and L2. I'd say about 0.7 volts is about correct. Ideally you would do a 2 tone IMD test to d
Do you have any application associated with the device controlling the radio? Also, if you are tuning to a signal using the dongle, it may be incorrect with regard to frequency thus this puts the Om
Largely because the dongle being used does not tune below or have adequate sensitivity below about 20 to 25 MHz. The IF in the Omni VII is about 70 MHz. 73 Bob, K4TAX On 8/30/2018 3:31 PM, Greg S
Even as a 2nd receiver, it is limited by the band pass filters in the front end of the Omni VII. As to using it in the IF, there is only about 2 MHz BW available from center frequency. I agree, u
Lee: Well a Tentec 563 is indeed an Omni VI, and is not a Plus. If the option 3 has been added, then it is an Omni VI opt3. That makes it close to having the features to a Omni VI Plus and many wil
These are typically MOLEX brand connectors of the IDC type. I suggest you download the MOLEX catalog and you can order as you need by model number from either Digi-Key or Mouser. Both have a good
Mike: Make sure the rubber ring on the outside of the knob has not been pushed back against the front panel. Otherwise, there are no adjustments. I have had inquiry as to how to add more drag. My s
Mike: Glad that resolved that part of the problem. As to making it smoother, this is usually a component or artifact of the encoder. Some are just smoother than others. I don't know anyway to imp
Operating system I presume is Windows 10? Firmware version in the Eagle is V2.003? Is the radio under CAT control from an application? If so, perhaps the port went to sleep and left the radio
Internally the Eagle has 2 fans which blow across the PA heat sink. However, there is a cross member about midway of the radio which has 3 regulators attached. This cross member serves as a heat
A comment on "properly designed system". Yes this is true but the "system" is the radio, the cables, the software application, the computer, the computer operating system and it is all designed and
There is an internal contrast adjustment. Don't know if this will help in your case. Replacement of the display is the option. And where to get one......don't have a clue. 73 Bob, K4TAX On 7/19/2
It appears that I will be selling my Tentec 238 tuner in the near future. This tuner was purchased new by me from Tentec in March 1996. I did replace the elastic dial cord and pilot lamps with ori
The last release of firmware is V2.3 or 2.003. The update application, along with instructions, and drivers if needed can be found on the Eagle site at Groups.IO. https://groups.io/g/TenTecEagle Loo
These are really good tuners. They handle lots and lots of power and have a very wide matching range. And they are efficient in doing so. In other words, they do not incur as much loss as many of t
Your description is typical of some component or components heating and changing value. This is not uncommon with this tuner, but usually with higher power. Three areas of concern are; (a) the 4
