The new filters are much sharper on the Jupiter. They are a big improvement over the 300 hertz filter. The RF gain control on the Jupiter now works like the latest Orion firmware. That is, as you red
The biggest difference between using a relay and a transistor is the time it takes to do the switch. A transistor will switch in a few microseconds. A relay will take in the order of 10 milliseconds
The TXOUT line is ground during transmit. You can use this line to the base of a PNP transistor to switch a 3 to 12 volt line on and off. You connect the base of the transistor through a 1K resistor
I looked at the schematic. Antenna 1 comes directly to a jack. If you have the tuner installed, there is a jumper from this jack that goes out directly to the tuner. If you don't have the tuner, ther
Grant, You are correct about what you say. But common sense would say that if they didn't want the tuner in the receive path, they would have just put the tuner in series with the transmit low pass f
Can you repeat the test with the tuner tuned to a low frequency like 80 or 160 meters? Or how about inputting a signal on 28 mhz that should be about S9 with the tuner properly tuned for that band an
Of course what you said is true, but it is still better to have a matched antenna on receive. There is always the possiblity of very low atmosheric noise on a given night and the extra signal just mi
My guess on the tuner is that it goes into bypass mode when you do a band change. I'm going to ask TT. Carl Moreschi N4PY 121 Little Bell Drive Bell Mountain Hays, NC 28635 -- Original Message -- Fro
My OII does fail in this scenario. I just did a battery reset followed by a master reset and it still fails. My fails with just 3 steps: 1) Set NB to 2 2) Set NR to 2 3) Turn on manual notch and it f
For people who have Tentec radios and did not get the internal tuner, LDG has just come out with a new tuner that is a little different. This tuner operates 100 % from software. There are no front pa
The rx340 is the very best but of course very pricey. Carl Moreschi N4PY 121 Little Bell Drive Bell Mountain Hays, NC 28635 -- Original Message -- From: "AL7CR" <al7cr@punakea.com> To: <tentec@contes
I have done extensive tests with transmitting with my OII and recording the received audio through my rx340. I am using my Heil HC5 goldline. The bottom line is the transmit audio with my Orion II is
To get excellent audio, the key is to not overdrive the radio. The ALC light should just occationally blink. I run my EQ settings at the factory settings and use a 2400 hertz transmit filter. I reall
I just got a response from TenTec about the internal tuner. The internal tuner is in line for both transmit and receive on the antenna 1 path. When a band change is done, the internal tuner is bypass
The 320D has a jack to bring out the 12 khz IF for DRM decoding to a sound card. That's the only difference. Carl Moreschi N4PY 121 Little Bell Drive Bell Mountain Hays, NC 28635 -- Original Message
Check the double RCA jumper on the back of the radio for the external VFO. Make sure it is making a good connection. Carl Moreschi N4PY 121 Little Bell Drive Bell Mountain Hays, NC 28635 -- Original
Bill, I don't know why I never thought of this before but I have a diversity mode in my N4PY Orion program. It sets the two radios to the same frequency as you tune with the remote tuning pod. I can
Yes, I have a full software frequency calibration routine. Carl Moreschi N4PY 121 Little Bell Drive Bell Mountain Hays, NC 28635 -- Original Message -- From: "Ron Castro" <ronc@sonic.net> To: "Carl M
If you run my N4PY Orion software in combination with MixW, all is well. MixW can be configured to work with my software and the OII in complete harmony. Carl Moreschi N4PY 121 Little Bell Drive Bell
The part number he gave you is exactly the correct one. A 20 amp fast breaker. Carl Moreschi N4PY 121 Little Bell Drive Bell Mountain Hays, NC 28635 -- Original Message -- From: "Kirk Braunius" <kbra
