The instructions on page 33 are good. Note the display PCB doesn't need to be removed from the front bezel, as the LEDs can be installed from the back side of the PCB after the old lamps are removed. Observe the correct polarity of the LEDs when installing. Also, with the LEDs, the DIMMER...

AM-W Frequencies were VHF range 119-123 MHZ SSB Frequency was 27.4 MHZ Problem could be mode switching, AM-FM to SSB or maybe band switching? I had a look at the schematic... seems like the place to start would be to look at the AGC line, that's what opens the squelch, and figure out...

OK.. 1. I setup the R7100 with several AM-W frequencies and one SSB frequency. 2. I radiate a signal from the sig gen and adjust level on the SSB frequency so that it's about S5 on the S-Meter. 3. I set the squelch so that the SSB frequency is squelched.. S5 and just a little bit more. 4...

The R7100 has two different types of squelch modes, by design. See below. It's a bit confusing. Note that the noise squelch operates only in the AM or FM mode. The threshold squelch operates in all modes and varies squelch based on signal strength. The two modes can't be combined. You use one or...

I setup my R7100 receiver as you described. I have several AM-W channels programmed (aircraft). I added an SSB channel and an FM-N channel. I then setup SCAN and mode MEMO (all channels). It works for me.. no pauses. What I do notice is that for the scan to work with the SSB channel, the...

Glad it works well ! I like the discone antenna in that it covers such a broad range of frequencies. Antennas for specific bands have more gain, but that said, having a path and antenna height are the most important factors in reception. I find here on 450 and 800 MHz bands, reception is...

I've made quite a few purchases from HRO in NH. No problems... I would recommend them.

I 'm located in Kennebunkport, Maine and use these two antennas (below) for scanning. Both are roof top mounted and fed with RG8 coax (Belden 8214). Coverage is good. The 800 MHz system in Portland comes in sometimes... I think if I had a bit more height and a directional Yagi, I could make...

Elad FDM S2 radio has AGC that sets the gain automatically and adjusts signal level to stay within the dynamic range the of the receiver. If you turn off the AGC, The GAIN adjustment sets the gain level. There is also a 12db attenuator option. See below: SW2 MAIN FUNCTIONS FOR RECEIVING MODE...

I own and use both SDR receivers. I like the RSP2 for VHF and UHF and the FDM-S2 for HF. It's hard to beat the FDM-S2 for features and performance on HF. The frequency coverage on the RSP2 goes to 2Ghz. I'd say get both ! Dave

I ran into the same issue with the TRX2 and control channel selection. There is a fix. Setup a separate (duplicate) system for each control channel under it's own ScanList. Problem is that you then have to edit the duplicate talk groups in each instance of the system rather than doing it in a...

I replaced my SD card and bought a USB to SD card adaptor. Now the card programs fine and much, much quicker! That problem is solved. While I was waiting for the adaptor and SD card from Amazon, I did some research and found the following information and explanation of how control channels are...

I tried a different approach and did like you suggested, with Library Import. 1. Clean install of EZScan with all previous stuff deleted. 2. Prepare Scanner SD Memory for use. 3. D/L RR Library and load to SD card 4. Using Import Library load Maine MSNet System 5. Delete System sites not...

This sounds to me like something is 'flaky' in the software with talk groups... Similar to what I'm seeing rarely stops on anything or works OK. I've been running a few days with a small selection of talk groups and everything works OK. PSR600 and TRX-02 capture same traffic...

I agree with what you're saying, except that: *Only one system is enabled - with two sites - one cc each site *conventional channels are disabled (not even loaded into scanner) *Data decode is 99% as measured for these both cc on the PSR600 It's a very basic configuration. With lots of...

to byndhlptom Maybe... But I would guess the data stream is buffered while compares and housekeeping task are performed. Almost certainly the I/O is handled by a DSP chip that would include QPSK decoding, buffering, vocoder for P25, etc... DSP chips have generous buffers! The...

to byndhlptom: That's a possible explanation, but I would think 100 talk groups to compare, isn't many. Lot's of unknowns, but I wouldn't think we would be talking 2 milliseconds for each compare, but more like 2 milliseconds for the whole set of 100 talk groups and I would assume the...

I have a TRX-2 and I'm new to this model. I notice a similar issue with State of Maine P25 system with lots of talk groups. I have a PSR600 running side by side with the TRX-2, same antenna with a splitter. With a few talk groups programmed into the TRX-2, I receive all traffic. When I put in...

You don't really copy them. They exist as an 'object'. Go to TRUNKED RADIO SYSTEMS tab. Select TALKGROUP DETAILS tab. Select the specific talkgroups you wish to monitor. Under SCANLISTS last column, enter specific scanlist(s) alphatag. by default alpha tags are named SCANLIST 001...

I'm not sure if many broadband receivers/scanners work in proximity to high power AM/FM broadcast stations. I have two FM stations about 1.5 miles away and the FM stations signal measured on my discone antenna is -30dbm. That's enough to screw up a lot of radios. My RS PRO 652 wouldn't work...
