Looking for an RF Gen similar to and possibly including the HP8640 with smooth generation down to -140-145dbm range rf coverage from 100 Khz - to at least 500 Mhz higher would be ok. To me used for rx testing in HF, with good freq accuracy tracable to NIST. Price range close to $1000. Suggest models and sources?

What is the difference between a RF channel and a virtual channel? The RF channel is the channel that the TV station uses to broadcast its signal. Before the conversion to digital, TV stations were normally identified by their channel number, and most people knew that a particular network was on a specific TV channel. While analog broadcasting was being phased out and all TV stations were converting to digital broadcasting, it was necessary for the TV stations to continue to broadcast their analog signals on their original RF channels, and also broadcast their digital signals on a different RF channel. However, since the TV station used their broadcast channel as part of their identification, they wanted to keep using the same channel number. To allow this to happen, the new digital television broadcasting standards (ATSC) provided TV stations the ability to continue to use their original channel number and also tell the TV set to tune to the new RF broadcast channel when their virtual channel number was selected. The original channel number is called the virtual channel number, and it will be followed by a period and a second number (3.1, 7.1, etc.).
One of the benefits of converting to digital for the TV stations is that they now have the ability to transmit more than one program at the same time on the same RF channel. The number of additional channels they can broadcast is determined by the resolution of the program (SD vs. HD, text only, music only, etc.). The second number in their virtual channel number indicates that one of the additional programming sources from the same TV station is being viewed (10.2, 10.3, 10.4, etc.).
When selecting an antenna, it is important to understand the difference between the RF broadcast channel and the virtual channel. Antennas are designed to receive specific ranges of RF channels, and the antenna needs to be selected for the RF channel you wish to receive. TV stations broadcast in two broad frequency ranges, called VHF and UHF. RF channels 2 through 13 are considered VHF, and RF channels 14 through 51 are considered UHF. In order to pick up the channels, the antenna has to be designed for the correct frequency range. It is very common today to find that TV stations using virtual channels 2 through 13 are actually using RF broadcast channels in the UHF range. Although not as common, some TV stations using virtual channels 14 through 51 are actually transmitting in the VHF range. An antenna designed for only UHF channels will not work effectively for RF broadcast channels in the VHF range, and an antenna designed for only VHF channels will not work effectively for RF broadcast channels in the UHF range.

you need a signal gen and tune down the RF strip

you need to center the pll first and its referance
then tune the IF for center

then tune the front end for max min max rf min noise using a reciever and a noise meter

good luck

If the radio is made to be sold only in the US then the phase lock loop is disabled when your are trying to transmit out of the US band edges. Try looking up a MARS circuit mod for this model and it amounts to only clipping one end of a diode to enable the transmitter on all frequencies.

The Sennheiser Set 820S is a TV/music listening system specially designed for hearing aid wearers. With roughly a 100 foot range, Set 820S users can leave the room while still being able to listen to a TV program or music. Enhanced with radio frequency (RF) technology for a larger coverage area, users won't need to worry about missing a word of the program or song. The Set 820S consists of the 820 RF stereo transmitter and 820-S RF stereo bodypack receiver. The transmitter connects to a TV set or hi-fi system; the receiver can be clipped to clothing. The receiver can be coupled with an induction neckloop (sold separately) (hearing aid must have a t-coil), direct audio connection (to cochlear implants or BTE hearing aid) or Sennheiser headphones with a 3.5mm jack. Two year warranty. · Bodypack receiver · RF wireless transmission · Stereo or mono operation · Quick charge feature · High SPL (125dB) · Approximately 100 foot range · Maximum volume and bass response adjustable by hearing professional

wireless speakers are also available ........ but you may not hear 100% of sound............. click above shown link.... you will find many similar products ...... you can check thier price , features, etc & then you can finalise the one that suits you best ..............

One highly possible issue could be that you may a sheared generator coupling, it connects the start gear to the generator to keep the battery charged. This happened to my RF and is somewhat common.

Adj VR1 next to VR2 they are in the center of the main motherboard. VR1 will allow you to adj the S meter in AM mode only.

I could not find a free manual, but this site is a lot lower in price.

Could anything other electronics be interfering with the signal?

I have the same remote as yours and occasionally the RF remote is not working due the interference signal from outside or next door at certain hours.
My suggestions:
(1) To relocate the receiver and reposition the anntena for better reception of the RF signal from the remote unit.
(2) Replaced the battery.

Hope these help!
