Up for sale on Hamradioauctions.com
A friend of mine, N5BZM, started up a new ham radio auction site for those who are ticked off at the big "Bay" site for their fees, etc..and it's now live.? is the site I am posting the following equipment: 1 DB products VHF BPBR 8-inch cavities duplexer 1 Telewave UHF BPBR duplexer 1 TPL UHF repeater amplifier 1 DB222 VHF antenna 1 SGC SG500 500 watt HF solid state amplifier (yeah I know it's not repeater or VHF but what the heck lol) and more to come. The HF amp is already posted and the rest of the equipment will be posted today Good day!? Chris WB5ITT Trustee W5APX? |

I was tuning up the transmit/low pass on my Sinclair Q2330E and came across an oddity when tuning the rejection notches on the low/transmit pass. It looks like there are 2 notches there, about 70Khz apart from each other. No matter how I adjust the notch caps, the double notches move together. The receive side tunes up perfectly and has one deep notch.My first thought would be cable lengths maybe? If this was tuned further up in the band, the cables may be a bit short. |

Re: Micor base station cabinets available
¿ªÔÆÌåÓýI have around 25-35 cabinets mostly the 6 foot ones. Most are almost new in a storage facility in Omaha along with other facilities loaded with brand new Micor parts still in boxes.? All heading to the dumpster around the first quarter of 2023.? Get your orders in now. I will post up here the exact dates they will be closed.? Also have Glenayre and other style cabinets in Michigan and Ohio areas.? Ken.? On Nov 8, 2022, at 19:06, Chris Boone <setxtelecom@...> wrote:

Re: Occupied bandwidth - (was Windows 7 config)
Touching again on OBW before moving on, in the other discussion I asked Burt to explain the procedure he uses to measure occupied bandwidth.
Burt replied:? "For occupied bandwidth measurements I use an Anritsu MS2721B spectrum analyzer.? I set the span to 100 kHz, the RBW (Resolution Bandwidth) to 100 Hz, and VBW (Video Bandwidth) to 30 kHz, and also use peak store.? With the repeater in use that has a mix of fully quieting and noisy signals I let the analyzer sweep for 10 minutes or longer." ?
The industry procedure uses the same 100 Hz RBW and since the goal of the OBW test pattern is to simulate normal modulation, either should produce comparable results
?
Once the trace is acquired most modern analyzers will compute the 99% OBW value at the touch of a button.? This will provide a baseline record for comparison to industry expectations and for comparison when experimenting with different transmit audio processing. |

Re: Quantar Audio Interfacing and Testing
In order to keep related material in one topic, here's a repost.
?
The Quantar Instruction Manual, 68P81095E05-B, shows a number of interface configurations.? Typically, transmit audio is input through wireline #1.
This is an excellent choice.? It is a transformer isolated, balanced input that can be connected to balanced or unbalanced devices.? It comes preset to 600-ohm impedance
but can be changed to other values, including high impedance, with configuration jumpers.? A nominal level of -10 dBm will result in 60% deviation,
?
When using wireline #1 as a transmit input, PTT is configured with a wildcard command.?
Use of wirelines and wildcard functions requires that the station be equipped with a wireline interface board.? If you have a Quantar without a wireline board, your only choice for
I/O is the 6809/MRTI interface.
?
Also, since low frequency audio is not passed through the wireline input, tone coded squelch [PL/DPL] can either be encoded by the station, or - if it is desired to generate this externally?input through J17-5 which must then be configured for Aux PL Audio.
The manual is somewhat unclear about the use of J17-5 so I did some research, and I prepared the attached document for clarification.
?
Finally, there is the Gen TX data +/- input which is intended for simulcast applications.? This input should be used with caution and requires the user to provide all transmit audio processing.
With this comes the risk of unacceptable transmit bandwidth.
?
Also make sure that the reference modulation compensation is correctly aligned to enure distortion free low frequency modulation. |
